Offset Adjustment of Analog Monitor Output (Fn00C)

This function is used to manually adjust the offsets for the analog monitor outputs (force reference monitor
output and motor speed monitor output). The offsets for the force reference monitor output and motor speed
monitor output can be adjusted individually. The offset values are factory-set before shipping. Therefore, the
user need not usually use this function.
(1) Adjustment Example
An example of offset adjustment to the motor speed monitor is shown below.

<Notes>
• Offset adjustment cannot be made if write protection is set in Fn010.
• The adjustment value will not be initialized when parameter settings are initialized using Fn005.
• Make offset adjustment with a measuring instrument connected, so that the analog monitor output is zero.
An example of settings for a zero analog monitor output is shown below.
• While the motor is not turned ON, set the monitor signal to the force reference.
• In speed control, set the monitor signal to the position error.
