Mitsubishi Electric MDS-B-SPJ2 Series Specification Manual page 82

6.2 Spindle parameters
Never drastically adjust or change the parameters. Extreme adjustments and changes of the
parameters will cause the operation to become unstable.
(1) Parameter list
(Note 1) With the MDS-B-SPJ2, all of the spindle parameters (total 384) can be set from the M500
CNC screen.
(Note 2) Parameters marked with a  in the CNG column can be set and changed when setting the
parameters with a personal computer without turning OFF the spindle drive unit power.

6. Status Display and Parameter Setting
CAUTION
Description
The orientation time will be reduced when the
value is increased and the servo rigidity will
increase. On the other hand, the vibration will
increase and machine sway will occur easily.
Same as above
Not used. Set to 0.
The position error range where the orient
complete signal is output is set.
The motor speed limit value for when changing
from the speed loop to position loop during
orientation is set.
When the setting value is 0, the limit speed will
be SP017 (TSP).
The orientation time will be reduced when the
value is increased. On the other hand, the
vibration will increase.
The orientation stop position is set.
Set a value that is 360° divided by 4096.
Not used. Set to 0.
The position loop gain for the spindle during
synchronous tapping is set.
The position loop gain for the spindle during
spindle synchronization is set.
Not used. Set to 0.
The motor's maximum speed is set.
The motor speed where zero speed is output is
set.
The time constant for the speed command from
0 to the maximum speed is set.
(This is invalid during position loop.)
The motor speed where the speed detection
output is performed is set. Normally, 10% of the
SP017 (TSP) value is set.
The torque limit ratio for when torque limit signal
001 is set.
The speed loop proportional gain during speed
control is set. The response will improve when
increased, but vibration and sound will increase.
