3.2.12
Adjust Analog Monitor Output Gain
(Fn00D)
You can use this utility function to manually adjust the analog monitor
output gains for the torque reference monitor and motor speed monitor.
You can adjust the torque reference monitor and motor speed monitor
gains individually.
These gains are adjusted at the factory. You normally do not need to use
this utility function.
The setting range for the analog monitor output gains is -128 to 127
(
×
0.4%).
The center value of the gain adjustment range is 100%.
For example, if you set -125, the gain will be 100% - (125
×
0.4%), or
50%. Therefore, the monitor output voltage will be reduced by 1/2. Also,
if you set 125, the gain will be 100% + (125
×
0.4%), or 150%. There-
fore, the monitor output voltage will be increased by a factor of 1.5.
Note: These offsets are not initialized even if you execute the Fn005 (Initialize Parame-
ters) utility function.
Preparations
Always check the following before you adjust gain of the analog monitor
output.
•
The parameters must not be write-prohibited (Fn010 must be set to
0000).
