Permissible voltages

The SIMODRIVE 611 drive system is dimensioned for direct operation on TN line supply

systems. The following table shows the permissible rated voltages of TN line supply systems

that apply to the motors.

In combination with the drive system SIMODRIVE 611, the motors are generally approved

for operation on TN and TT networks with grounded neutral and for IT networks. A protective

device should be provided for operation on IT networks, which switches off the drive system

in the case of a ground fault. In operation with a grounded external conductor, an isolating

transformer with grounded neutral (secondary side) must be connected between the supply

and the drive system to protect the motor insulation from excessive stress.
Adaptation transformers that have been tailored to the system are available for operation on

IT or TT line supply systems.

Requirements

● The power unit is selected depending on the motor current at torque M

and a speed 1

[rev/min] or according to the maximum motor current.

● The motors should be set up as synchronous rotation motors (SRM).
● The encoder system used must be harmonized with the particular application.

Drive systems

The following SINUMERIK/SIMODRIVE systems are suitable:
● SIMODRIVE 611 digital with High-Performance or High-Standard control modules in

conjunction with SINUMERIK 840 D or SINUMERIK 810D

● SIMODRIVE 611 universal HRS
● SINUMERIK 810D CCU-3
