49 Gain switching selection
Used to select the gain switching condition.
0 0 0
Gain switching selection
Gain will be changed under the
following conditions based on the
setting value of parameters No. 52 to
55.
0: Disabled
1: Controller command
2: The appointed frequency is equal
to or more than the setting value of
parameter No. 50
3: The droop pulse is equal to or
more than the setting value of
parameter No. 50
4: The servo motor speed is equal to
or more than the setting value of
parameter No. 50
50 Gain switching condition
Used to set the values for the gain switching conditions
(command frequency, droop pulses, and servo motor
speed) selected in [Pr. 49].
The set value unit differs depending on the switching
condition item.
51 Gain switching time constant
Used to set the time constant at which the gains will switch
in response to the conditions set in [Pr. 49] and [Pr. 50].
52 Load to motor inertia ratio 2
Used to set the load to motor inertia ratio when gain
switching is enabled.

PB27 Gain switching condition
Used to set the values for the 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.
PB28 Gain switching time constant
Used to set the time constant till the gain switches in
response to the conditions set in [Pr. PB26] and [Pr.
PB27].
PB29 Load to motor inertia ratio after gain switching.
Used to set the load to motor inertia ratio when gain
switching is enabled.
This parameter is enabled only when "Manual mode
(_ _ _ 3)" is selected in "Gain adjustment mode selection"
of [Pr. PA08].
