Description
PB26
CDP
Gain switching function
Select a switching condition.
PB27
CDL
Gain switching condition
[kpulse/s]
/[pulse]
/[r/min]
Set a switching condition values.
PB28
CDT
Gain switching time constant
[ms]
Set the filter time constant for a gain switch at switching.
(a) [Pr. PB26 Gain switching function]
Set gain switching conditions. Select the switching condition in the first to third digits.
Gain switching selection
0: Disabled
1: Control command from controller is enabled
2: Command frequency
3: Droop pulses
4: Servo motor speed/linear servo motor speed
0
Gain switching condition
0: Gain after switching is enabled with gain switching condition or more
1: Gain after switching is enabled with gain switching condition or less
[Pr. PB26]
Gain switching time constant disabling condition selection (Note)
0: Switching time constant enabled
1: Switching time constant disabled
2: Return time constant disabled
Note. This digit is available with servo amplifier with software version B4 or later.
(b) [Pr. PB27 Gain switching condition]
Set a level to switch gains with [Pr. PB27] after you select "Command frequency", "Droop pulses", or
"Servo motor speed/linear servo motor speed" with the gain switching selection in [Pr. PB26 Gain
switching function].
The setting unit is as follows.
Gain switching condition
Unit
Command frequency
[kpulse/s]
Droop pulses
[pulse]
Servo motor speed/linear servo motor speed
[r/min]/[mm/s]
(c) [Pr. PB28 Gain switching time constant]
You can set the primary delay filter to each gain at gain switching. Use this parameter to suppress
shock given to the machine if the gain difference is large at gain switching, for example.
