EC Electric Motors – G6 Series
Servomotors with integrated electronics
Controlling
G6 Series motors control position, speed or torque similarly as conventional servomotors. The parameter setting, controlling and diagnostics is carried out trough series communication interfaces such as RS232 / RS485 or CAN.

“ECMotor Control” Programme – Graphic User Interface
Simple open communication protocol
Commands for parameter setting and motion control such as: position control, speed control, torque control, PID constant setting
Commands for parameter reading and motor status detection such as: motor current detection, winding temperature detection, status word detection, etc.
Motion parameters can be changed during motion
User Programme
User programme is a sequence of commands defined by the user and downloaded to the motor through “EC Motor Control” programme. The motor can be then controlled by sequences of commands executed trough the communication link or by changing the input parameters.

Commands for parameter setting and motion control
Setting and testing of user variables and bits, conditionally branch, sub­programmes, time delay definition, and commands for driving of I/O modules. Up to two command sequences can be applied simultaneously (e.g. logical functions of the motor & trajectory definition).
User programme is stored in EEPROM memory.
The user programme starts automatically after power­up.
Utilising of I/O modules without the need of a communication link.
Complex control of simple mechanical machine.

The design of the G6 Series Electric Motors follows the global trend in motion control. The electrical as well as mechanical elements of the drive are all integrated in one unit comprising of position sensor, control as well as power electronics and if required also a PLC. The advantage of this construction becomes apparent when you focus at the design, implementation, operation, service and maintenance of this electrical drive when compared with conventional drive systems.
Reduced costs when designing a drive system

The integral unit replaces a number of drive elements and their mutual intercon­
nection.
Complete mechanical solution, integrated I/O modules, and user programme.
Virtually no issues with the EMC as the electronic unit is located in one metal enclosure.
No control element to be built in control cabinets results in reduction of space.

G6 Series motors are based on totally enclosed flange mounted 6pole permanent magnet electric motors. The permanent magnets (Nd­Fe­B) form part of the rotor. The integrated power as well as control electronics enable the unit to function as vector controlled servo drive. The use of the integrated absolute position sensor guarantees no random rotor movement at power­up. The compact design and the metal enclosure enable good resistance against external interference and minimise self­radiation. There are no further EMC filtering necessary for industrial environment classified as class B (to EN 55022). The use of G6 Series motors is specifically advantageous at applications where the combination of standard squirrel cage motor driven through a frequency inverter does not offer a satisfactory solution and the use of conventional servomotors or indeed stepper motors does not prove not to be the economically viable solution.
