SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Enables selection of various pulse types. Only bits 04 and 05 are used.
Description: Specifies the number of encoder pulses per revolution.
Note: The encoder resolution (pulses per revolution P0408) which may be entered will be limited by the max. pulse fre-
quency of the encoder circuits (f_max = 300 kHz).
The following equation calculates the encoder frequency depending on the encoder resoulution and the rotational
speed (rpm). The encoder frequency has to be less than the max. pulse frequency:
Description: Reverses internal direction sense of the encoder signal. This does the same thing as switching the ENC_A and
ENC_B signals.
Values: 0: Encoder Normal Rotation
1: Encoder Reverse Rotation
