Setting The Output Magnification; Current Feedback Analog Output Function - Mitsubishi Electric MELDAS MDS-R Series Specifications And Instruction Manual

9-1-3 Setting the output magnification

Set as follows to output with a unit other than the standard output unit.
(Example 1) When SV061 = 11 and SV063 = 2560
(Example 2) When SV062 = 11 and SV064 = 128
No. Abbrev.
SV063 DA1MPY D/A output channel 1 output
SV064 DA2MPY D/A output channel 2 output

9-1-4 Current feedback analog output function

Use this function to measure the resonance frequency when adjusting machine resonance suppression
filter.
The phase current is output to the CN9
pin. Connect a high-speed waveform
recorder, etc. between the GND (pin 1)
and the phase current to be measured,
and observe the state.

The position droop is output as a 0.1mm/V unit to D/A output channel 1.
The position droop is output as a 2mm/V unit to D/A output channel 2.

Set the speed loop gain (SV005: VGN1) to approx. 50 to 100, disconnect the
resonance filter, and measure the waveform while the axis is stopped.

9. Adjustment
Explanation
When "0" is set, the data is output with the standard output unit.
Set a value other than 0 to change the output unit.
The scale is set with a 1/256 unit. When 256 is set, the unit is the
same as the standard output unit.
