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.
Gain-adjustment Range
Adjustment Unit
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.
