PB26 Gain changing selection
Select the gain changing condition. PB26 Gain switching function
Select the gain switching condition.
Set conditions to enable the gain switching values
set in [Pr. PB29] to [Pr. PB36] and [Pr. PB56] to [Pr.
PB60].

PB27 Gain changing condition
Used to set the value of gain changing condition
(command frequency, droop pulses, servo motor
speed) selected in [Pr. PB26].The set value unit
changes with the changing condition item.

Gain switching condition
This is used to set the value of gain switching
(command frequency, droop pulses, and servo
motor speed) selected in [Pr. PB26].
The set value unit differs depending on the switching
condition item.
Setting range: 0 to 9999
PB28 Gain changing time constant
Used to set the time constant at which the gains will
change in response to the conditions set in [Pr.
PB26] and [Pr. PB27].
1 PB28

S
Gain switching time constant
This is used to set the time constant at which the
gains will change in response to the conditions set in
[Pr. PB26] and [Pr. PB27].
Setting range: 0 to 100
PB29 Gain changing ratio of load inertia moment to servo
motor inertia moment
Used to set the ratio of load inertia moment to servo
motor inertia moment when gain changing is valid.
This parameter is made valid when the auto tuning
is invalid ([Pr. PA08]: _ _ _ 3).
7.0 PB29
Same as MR-J3

P
S
load to motor mass ratio after gain switching
This is used to set the load to motor inertia ratio/load
to motor mass ratio when gain switching is enabled.
This parameter is enabled only when "Gain
adjustment mode selection" is "Manual mode (_ _ _
3)" in [Pr. PA08].
Setting range: 0.00 to 300.00 Unit: 1.0 time
PB30 Gain changing position loop gain
Set the position loop gain when the gain changing is
valid.
This parameter is made valid when the auto tuning
is invalid ([Pr. PA08]: _ _ _ 3).
37 PB30 Position loop gain after gain switching
Set the position loop gain when the gain switching is
enabled.
When you set a value less than 1.0 rad/s, the value
will be the same as [Pr. PB08].
This parameter is enabled only when "Gain
adjustment mode selection" is "Manual mode (_ _ _
3)" in [Pr. PA08].
Setting range: 0.0 to 2000.0
