7.4.3.2 Analog Torque Gain
Analog input voltage range is -10V to +10V. In analog torque mode, the drive must be told how much
current is required for a given analog input voltage. This can be configured via M Servo Suite or
parameter P-51 (AN) directly from the drive’s control panel.

7.4.3.3 Analog Input Offset
In some cases, when a host controller has set the analog command to 0V, the servo motor might still
rotate slowly. This is caused by voltage bias from the analog device. M Servo Suite can automatically
offset the analog voltage bias, or it can be manually tune by changing parameter P-53 (AV2).
