6 Spindle Adjustment
MITSUBISHI CNC
【#13082】 SP082 IDAL D axis current lead compensation low-speed coil
When using coil switch function, set the current loop gain for when the low-speed coil is selected.
The setting value is determined by the motor's electrical characteristics so that the value is fixed to
each motor used.
Set the value given in the spindle parameter list. (For machine tool builder adjustment)
---Setting range---
1 to 20480
【#13083】 SP083 IQGL Q axis current gain low-speed coil
When using coil switch function, set the current loop gain for when the low-speed coil is selected.
The setting value is determined by the motor's electrical characteristics so that the value is fixed to
each motor used.
Set the value given in the spindle parameter list. (For machine tool builder adjustment)
---Setting range---
1 to 8192
【#13084】 SP084 IDGL D axis current gain low-speed coil
When using coil switch function, set the current loop gain for when the low-speed coil is selected.
The setting value is determined by the motor's electrical characteristics so that the value is fixed to
each motor used.
Set the value given in the spindle parameter list. (For machine tool builder adjustment)
---Setting range---
1 to 8192
(Note) Low-speed coil setting SP081, SP082, SP083 and SP084 are set to "0" when coil changeover specification is not
available.
(2) Adjusting the gain parameter
Adjust the gain parameters as usual or by application in accordance with the chart below.
(Note) Position and speed loop gain is switched depend on the control item, so set the parameter correctly.
