7 Utility Functions (Fn)7-167.9 Gain Adjustment of Analog Monitor Output (Fn00D)If connecting an analog monitor unit, the analog monitor signal output (factory setting: torque monitor ormotor speed monitor) can be monitored. The gain is adjusted in the analog monitor unit at the factory. Theuser need not usually use this function. To adjust the gain manually, use this function.(1) Adjustment ExampleAn example of gain adjustment to the motor rotating speed monitor is shown below.The gain adjustment range is made with a 100% output set as a center value (adjustment range: 50% to 150%).The following is a setting example. −125>100% + (−125 × 0.4) = 50%Therefore, the monitor output voltage is 0.5 time as high.100% + (125 × 0.4) =150%Therefore, the monitor output voltage is 1.5 times as high.Note: The adjustment value will not be initialized when parameter settings are initialized using Fn005.(2) PreparationThe following condition must be met to adjust the gain of the analog monitor output.• The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).Item SpecificationsGain-adjustment Range 100±50%Adjustment Unit 0.4%/LSBAnalog monitoroutput voltageGain adjustmentMotor speed1 [V]1000 [min-1 ]
