Motor Components (Options)
Encoder
4.4.3 Resolver
Function:
• Speed actual value sensing
• Rotor position encoder for inverter control
• Indirect incremental measuring system for the position control loop
Fig. 4-3 Resolver output signals
Notice
The max. operating frequency of 432 Hz must be observed with SIMODRIVE 611 universal.
Encoder frequency = speed x pole pair number of the resolver/60
