Torque Offset Source
Default: 0
Settings 0: Disable
1: Analog signal input (Pr.03-00)
2: Pr.11-29
3: Controlled by external terminal (Pr.11-30–Pr.11-32)
 Determines the source for the torque offset.
 When it is set to 3 (external terminal control), the torque offset source follows Pr.11-30, Pr.11-31
or Pr.11-32 as the combination of MI setting as 31, 32 or 33 commands. Refer to the following
chart:
Normally open (N.O.) contact: ON = contact closed, OFF = contact open
