SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Selects encoder type (number of encoder channels).
Values: 0: Disabled
2: Quadrature encoder without zero pulse
12: Quadrature encoder with zero pulse
Caution: When using Vector Control with encoder-feedback, the direction of rotation of the encoder and motor must be the
same. If this is not achieved, then the functional operation of the Vector Control will not be guaranteed (positive
instead of negative feedback).
Extreme care must therefore be taken with respect to the connection of the motor to the inverter as well as the cor-
rect connection of the encoder to the inverter. Motor and encoder must not be incorrectly wired up !
P0400 = 12 (quadrature encoder and zero pulse) will not detect encoder loss on Zero pulse. Zero pulse is only used
to synchronise measured angle.
Note: If the encoder is enabled (P0400 > 0) and the motor holding brake is enabled (P1215 > 0), then the following should
be observed in order to stop encoder loss trips when the brake is applied:
• The delay speed loss reaction should be > brake holding times (i.e. P0494 > P1216 and P0494 > P1217 )
• The delay time for motor pulled out should be > brake holding times (i.e. P2178 > P1216 and P2178 > P1217 )
• The allowed speed difference P0492 should be > f_min P1080
Description: Displays status word of encoder (in bit format).
