MDS-D-SVJ3/SPJ3 Series Instruction Manual
5-2 Adjustment procedures for each control
【#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 1) The speed loop gain can switch from Set 1 to Set 2 with the bit selection for SP035.
(Note 2) Position and speed loop gain is switched depend on the control item, so set the parameter
correctly.
(Note 3) When "#3106 bitE" is set to "1".
(Note 4) When "#3106 bitE" is set to "0".
