Parameter
No.
Description
Setting
Validation
Function and Meaning
Pn119
Setting
acceleration
speed switching
threshold
Immediately
Threshold of acceleration speed to switch PI control to P
control.
Unit: 10 rpm/s
Pn120
Setting speed
switching
threshold
Immediately
Threshold of speed to switch PI control to P control.
Unit: rpm
Pn121
Gain switching
condition
After restart
0: Fix to 1st group gain
1: External switch gain switching (G-SEL)
2: Torque percentage
3: Reserved
4: Value of acceleration speed setting (10 rpm)
5: Value of speed setting
6: Speed reference input
Pn122
Switching delay
time
Immediately
Delay time of switching gain when switching condition is
satisfied.
Pn123
Switch
threshold level
Immediately Gain switching trigger level.
Pn124 Reserved — —
Pn125 Reserved — —
Pn126
Hysteresis
switching
Immediately
This parameter is used to set the operation hysteresis of gain
switching.
Pn127
Low speed
detection filter
Immediately
This parameter is used to filter in low speed detection. The
speed detection will be lagged if the value is too large.
Pn128
Speed gain
acceleration
relationship
during
online
autotuning
Immediately
The increasing multiple of speed loop gain in the same rigidity
during online autotuning. The speed loop gain is larger when
this value is higher.
Pn129
Low speed
correction
coefficient
Immediately
The intensity of anti-friction and anti-creeping at low speed.
Vibration will occur if this value is set too large.
Pn130 Reserved — —
Pn146
Feedback
speed low pass
filter
After restart See attached table -1
Pn147
Current loop
gain
After restart See attached table -1
Pn148
Current loop
integration
After restart See attached table -1
Pn149
Power delay
function for
brake
After restart
Recommended value is 400, the driver will try to control the
motor 400 msec after it detects that it has to release control.
