It can operate as a distributed drive using the CANopen or DeviceNet protocols, or as a stand-alone drive accepting analog or digital commands from an external motion controller. In stand-alone mode, current and velocity modes accept digital 50% PWM or PWM/polarity inputs as well as ±10V analog. In position mode inputs can be incremental position commands from step-motor controllers, analog ±10V, or A/B quadrature commands from a master-encoder. Pulse to position ratio is programmable for electronic gearing. Drive commissioning is fast and simple using CME 2™ software operating under Windows® and communicating with Accelnet via CAN or an RS-232 link. CANopen is the default protocol, DeviceNet is supported by downloading firmware from the web-site. CAN address selection is by a 16-position rotary switch. If there are more than sixteen devices on the CAN bus, the additional address bits needed can come from programmable inputs, or can be set in flash memory. Copley Controls, 20 Dan Road, Canton, MA 02021, USA Web: www.copleycontrols.com Ic 10 Ip 20 Vdc 18~55 800-1638 operates as Motion Control Device under the DSP-402 protocol of the CANopen DS-301 V4.01 (EN 50325-4) application layer. DSP-402 modes supported include: Profile Position, Profile Velocity, Profile Torque, Interpolated Position Mode (PVT), and Homing. The two CAN ports are optically isolated from drive circuits. There are ten digital inputs nine of which have programmable functions. These include CAN address, motion-abort, limit & home switches, stepper/encoder pulse inputs, reset, digital torque or velocity reference, and motor over-temperature. Input [IN1] is dedicated for the drive Enable. There are four programmable logic outputs for reporting an drive fault, motor brake control, or other status indications. Drive power is transformer-isolated DC from regulated or unregulated power supplies. An AuxHV input powers control circuits for “keep-alive” operation permitting the drive power stage to be completely powered down without losing position information, or communications with the control system.

CME 2 software communicates with the drive over this link for commissioning and adjustments. When operating as a stand-alone drive that takes command inputs from an external controller, CME 2 is used for configuration. When operated as a CAN node, CME 2 is used for programming before and after installation in a CAN network. 800-1638 can also be controlled via CME 2 while it is in place as a CAN node. During this process, drive operation as a CAN node is suspended. When adjustments are complete, CME 2 relinquishes control of the drive and returns it to the CAN node state. Multiple drives can communicate over a single RS-232 port by daisychaining the master drive to other drives using CAN cables. The master drive does the RS-232 communication with the system and echoes the commands to the other drives over the CAN bus. Drive setup is fast and easy using CME 2 software. All of the operations needed to configure the drive are accessible through this powerful and intuitive program. Auto-phasing of brushless motor Hall sensors and phase wires eliminates “wire and try”. Connections are made once and CME 2 does the rest thereafter. Encoder wire swapping to establish the direction of positive motion is eliminated. Motor data can be saved as .ccm files. Drive data is saved as .ccx files that contain all drive settings plus motor data. This eases system management as files can be cross-referenced to drives. Once a drive configuration has been completed systems can be replicated easily with the same setup and performance. AR IN DRIVE status LEDS Y RS-232 communication CANopen communications IM Three bi-color LEDs gives the state of each axis by changing color, and either blinking or remaining solid. The possible color and blink combinations are: • Green/Solid: Axis OK and enabled. Will run in response to reference inputs or CANopen commands. • Green/Slow-Blinking: Axis OK but NOT-enabled. Will run when enabled. • Green/Fast-Blinking: Positive or Negative limit switch active. Axis will only move in direction not inhibited by limit switch. • Red/Solid: Transient fault condition. Axis will resume operation when fault is removed. • Red/Blinking: Latching fault. Operation will not resume until drive is Reset EL Based on the CAN V2.0b physical layer, a robust, two-wire communication bus originally designed for automotive use where low-cost and noise-immunity are essential, CANopen adds support for motion-control devices and command synchronization. The result is a highly effective combination of data-rate and low cost for multi-axis motion control systems. Device synchronization enables multiple axes to coordinate moves as if they were driven from a single control card. CANopen connectivity 800-1638 uses the CAN physical layer signals CANH, CANL, and GND for connection, and CANopen protocol for communication. Each axis is assigned a non-zero node address that is stored in flash memory. A maximum of 127 CAN nodes are allowed on a single CAN bus. The CAN port is optically isolated from the drive circuits and each signal is duplicated in the CAN connector J8 to faciliate daisy-chain wiring from drive to drive. CANopen control PR Control of the drive is via a CAN bus using the CANopen protocol.

Each output has a (+) and (-) terminal and can be connected to source or sink current. Digital output [OUT3] is an open-drain MOSFET with 1 kΩ pull-up resistors in series with a diode to +5 Vdc. Digital output [OUT4] is an open-drain MOSFET with a flyback diode to the 24V input. These can sink up to 1.5 Adc from external loads operating from power supplies to +30 Vdc. The outputs are typically configured as drive fault and motor brake. Additional functions are programmable. As a brake output, it is programmable to be either HI or LO to release a motor brake when the drive is enabled. When driving inductive loads such as a relay, an external fly-back diode is required on [OUT3]. A diode in [OUT3] is for driving PLC inputs that are opto-isolated and connected to +24 Vdc. The diode prevents conduction from +24 Vdc through the 1 kΩ resistor to +5 Vdc in the drive.

The phase connections carry the drive output currents that drive the motor to produce motion. A thermal switch that indicates motor overtemperature is used to shut down the drive to protect the motor. motor phase connections P1-1 Motor Outputs V W AR Each axis output is dual PWM H-bridges that drive the two motor phases in bipolar mode. Cable should be sized for the continuous current rating of the axis. Motor cabling should use twisted, shielded conductors for CE compliance, and to minimize PWM noise coupling into other circuits. The motor cable shield should connect to motor frame and the drive HV ground terminal (J1-4) for best results. HV_COM = Shielded cables required for CE compliance digital MOTOR ENCODER EL IM IN The input circuit for the motor encoder signals is a differential line-receiver with R-C filtering on the inputs. A 121Ω resistor is across each input pair to terminate the signal pairs in the cable characteristic impedance. Encoders with differential outputs are required because they are less susceptible to noise that can be picked on single-ended outputs. For best results, encoder cabling should use twisted pair cable with one pair for each of the encoder outputs: A-/A, B-/B, and X-/X. Shielded twisted-pair is even better for noise rejection.

StepNet Driver P1-3 MOTOR 3.3 nF 800-1634 operates typically from transformer-isolated, unregulated DC power supplies. These should be sized such that the maximum output voltage under high-line and no-load conditions does not exceed the drivers maximum voltage rating. Power supply rating depends on the power delivered to the load by the driver. (+) V +5V Hall signals are single-ended signals that provide absolute feedback within one electrical cycle of the motor. There are three of them (U, V, & W) and they may be sourced by magnetic sensors in the motor, or by encoders that have Hall tracks as part of the encoder disc. They typically operate at much lower frequencies than the motor encoder signals, and are used for commutation-initialization after startup, and for checking the motor phasing after the drive has switched to sinusoidal commutation. +HV P1-2 J6-3,5,1 MOTOR HALL SIGNALS POWER Supplies U Y U CANopen communications with 800-1638 can be maintained when +HV is turned off by using the Aux HV input. The voltage has the same range as +HV, and can be greater or less than +HV. In operation, the Aux HV keeps the driver logic and control circuits active so it is always visible as a node on a CAN bus. The current-position data is maintained making ‘homing’ unnecessary after system power is re-enabled. If 800-1638 is operating as a stand-alone driver, Aux HV is not necessary but can be useful if the controller is monitoring driver digital outputs.

Control I/O V MOTOR W P1 J4 Signal Gnd Aux +HV HV_COM + Power - Supply + Power - Supply Keep as short as possible Equipment frame Earth Keep connections as close as possible. "Star" ground to a common point is best PR EL IM IN Signals from controller to driver are referenced to +5 Vdc, and other power supplies in user equipment. These power supplies should also connect to system ground and earth at some point so that they are at same potential as the driver circuits. The final configuration should embody three current-carrying loops. First, the power supply currents flowing into and out of the driver at the +HV and HV_COM pins on P1. Second the driver outputs driving currents into and out of the motor phases, and motor shield currents circulating between the U,V, & W outputs and HV_COM . And, lastly, logic and signal currents connected to the driver control inputs and outputs. U Y Because current flow through conductors produces voltage-drops across them, it is best to connect the driver HV_COM to system earth, or circuitcommon through the shortest path, and to leave the power-supply floating. In this way, the power supply (-) terminal connects to ground at the driver HV_COM terminal, but the voltage drops across the cables will not appear at the driver ground, but at the power supply negative terminal where they will have less effect. 800-1638 Controller AR Power and control circuits in 800-1638 share a common circuit-ground (HV_ COM on P1-4, Signal Ground on J3-7, J4-7,8,28, J5-2, and J6-8,9. Input logic circuits are referenced to Signal Ground, as are power GND, digital outputs, and encoder. For this reason, driver Gnd terminals should connect to the users’ common ground system so that signals between driver and controller are at the same common potential, and to minimize noise. The system ground should, in turn, connect to an earthing conductor at some point so that the whole system is referenced to “earth”.
