Manual Gain-adjustment of Analog Monitor Output (Fn00D)

This function is used to manually adjust the gains for the analog monitor outputs (force reference monitor out-
put and motor speed monitor output). The gains for the force reference monitor output and motor speed moni-
tor output can be adjusted individually. The gain values are factory-set before shipping. Therefore, the user
need not usually use this function.
(1) Adjustment Example
An example of gains adjustment to the motor speed monitor is shown below.
The gain adjustment width is made with a 100% output set as a center value (adjustment range: 50% to 150%).
A setting example is shown below.
<Setting the Set Value to −125>
100% + (−125 × 0.4%) = 50%
Therefore, the monitor output voltage is 0.5 times as high.
<Setting the Set Value to 125>
100% + (125 × 0.4%) =150%
Therefore, the monitor output voltage is 1.5 times as high.

<Notes>
• Gain 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.
