CU240S DP
Quick comm. YES
CU240S DP-F
Can be changed: C, T
CU240S PN
Min
2
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.
