You can manually adjust the offset and gain for the analog monitor outputs for the torque
reference monitor and motor speed monitor.
The offset is adjusted to compensate for offset in the zero point caused by output voltage
drift or noise in the monitoring system.
The gain is adjusted to match the sensitivity of the measuring system.
The offset and gain are adjusted at the factory. You normally do not need to adjust them.
An example of adjusting the output of the motor speed monitor is provided below.
