Single signal generated from 24 V High
Threshold Logic (HTL) encoder connected to
terminals 27 and 29. Configure the 24 V
encoder interface in parameter group 5.7* 24V
Encoder Input.
Program terminals 27/29 to [0] No operation.
No position feedback is received. This means
that actual position remains unchanged. For
example, when the drive is used for operating
