Speed Bias Function; Orientation Function - Omron SYSDRIVE RX Series User Manual

4-3 Functions When Option PG Board (3G3AX-PG01) Is Used

Speed Bias Function

This function applies speed command bias in the pulse train position control mode.
Set a bias value in frequency addition amount A145, and select a sign in frequency addition direc-
tion A146.
Allocate 50 (ADD) to any of the multi-function inputs. While the ADD terminal is turned on, the bias
value is added to the speed command.
