Functions
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.
Orientation Function
This function determines a motor position at a single desired point during one rotation of the motor,
and can be used to exchange tools for the machine tool main spindle or others.
During positioning, the Z-pulse (one rotation position signal) is used as the reference signal. Input
Z-pulse between EZP and EZN.
