1. GENERAL REQUIREMENTS
This section provides general requirements for pulse-width modulated (PWM) adjustable
frequency drives, herein referred to as AC Drives, for use with NEMA design AC motors, or
standard IEC motors.
The AC drive shall provide a power from 0,18kW to 4 kW and a voltage supply from 120V
(single phase) to 240V (single phase or three phases).
The AC drive is a system for controlling the rotational speed of an AC motor and providing on
demand the right torque for a simple application in industry or residential areas.
To avoid any mismatch between the motor and its control equipment, the AC drive shall be
capable of auto adjustment by automatic measurement of the motor parameters without motor
rotation.
The AC drive shall be noiselessly (< 50dba). There is a fan management for the AC drive above
0,75kW. Until 0,75kW, the AC drive doesn’t need a fan.
The AC drive shall provide a braking torque up to 70% of the nominal torque without resistor
and up to 150% of the nominal motor torque with an optional braking unit at high inertia.
2. APPLICABLE STANDARDS
The AC drive is qualified to address all the major standards in order to be worldwide
commercialized.
The AC drives shall be:
 CE marked, conforming to European Low Voltage (2006/95/EC modified from
73/23/EEC and 93/68/EEC and EMC (2004/108/EC modified from 89/336/EEC)
Directives, and Machinery directive N0 98/37/EC modified by 98/79/EC,
 UL marked according to UL 508C,
 CSA marked according to CSA 22.2 N14-05,
 C-Tick marked to comply with Australasian Communication Authorities,
 NOM marked (Mexican area),

3. SPECIFIC REQUIREMENTS
3.1. Protection
The AC drive must have fault detection against the risks of equipment destruction from
component’s failures. The AC drive shall:








be protected against short-circuits between motor and phases;
be protected against the over current between motor phases and earth;
have a thermal protection against overheating;
have an input phase loss protection, in three-phases;
be protected in the event of line over voltage and under voltage;
have a thermal protection integrated in the drive;
be IP20;
have coated cards in order to fight the pollution (IEC 60721-3-3 classes 3C3 and 2S2).
3.2. Commissioning
The AC drive must be “plug & play”. For simple applications, the factory settings are enough to
get a quick start (a quick start sheet is delivered with the product).
The navigation of the AC drive is done by the jog dial. The START; STOP/RESET buttons on
face allow to have a local control.
The AC drive can be configured power OFF in his box thanks to a loader toll. This possibility
allows saving time: the user can configure 10 drives power OFF during 5 minutes.
The AC drive shall be compatible with friendly PC software which allows the user to configure
the drive and to store configurations. This PC software must have the oscilloscope function
which facilitates the diagnostics. The PC software allows selecting the number of the
parameters that the user wants (by selecting the box ‘YES’ or ‘NOT’ on the screen of the
software).
The AC drive allows the configuration with a cell phone throughout Bluetooth. The user will find
the application for his cell phone on a website. He can download it free of charge.
3.3. Control and power connections
The control voltage for the digital inputs and outputs shall be 24Vdc.The input logic type source
(positive logic) or sink (negative logic) can be configured.
The internal power supply shall incorporate automatic current feedback that protects the
internal power supply against wrong connections or short-circuits. The transistor logic outputs
will be current limited and will not be damaged if short-circuit occurred.
One relay output contact will be provided. The relay will indicate AC drive fault status or no line
voltage present (NO - NF relay).
The power terminals of the AC drive are compatible with the ring terminals.
The analog inputs have an accuracy of +/-1% at 25 °C.
The logic inputs have an update time lower than 20 ms (with a precision of +/- 1ms).

3.4. Integration on a solution offer
The AC drive must have the possibility to be integrated on automatism solution. The AC drive
shall have an integrated RJ45 port for Modbus as a standard product.
3.5. Software
The AC drive shall offer a simple menu divided in 3 modes in order to find a parameter easily:
 “Reference” ,
 “Monitoring” ,
 “Configuration” with 2 parts (“My Menu” and “FULL Menu”)
The AC drive shall provide 3 motors control laws:
 “Standard” (based on the U/f law) which allows to have a smooth and a quick start for
all types of motors,
 “Performance” (based on SVC law) which allows a TUN and is compatible with the
different type of motors,
 “Pump & fan” which allows saving energy.
The AC drive shall offer a personalized menu (named “MyMenu”). The user can customize the
AC drive thanks to PC software. The user can choose 25 parameters to personalize his menu.
