1 SERVO PARAMETER DETAILS
1.3 Gain/filter setting servo parameters group ([Pr. PB_ _ ])
[Pr. PB26.5_Gain switching selection during a stop]
0: Gain switching 2 during a stop is disabled
1: Gain switching 2 during a stop is enabled
This servo parameter is enabled in the following condition: [Pr. PB26.4 Gain switching 2 selection] is set to "2" (the same
condition as [Pr. PB26.0 Gain switching selection]) and [Pr. PB26.0] is set to "5" (command direction) in the position mode.
[Pr. PB27_Gain switching condition (CDL)]
Set the value of the gain switching (command frequency, droop pulses, or servo motor speed) selected in [Pr. PB26 Gain
switching function].
The set value unit differs depending on the switching condition item. The units are as follows: [kpulse/s] for command
frequency, [pulse] for droop pulses, and [r/min] for servo motor speed.
If using a linear servo motor, the unit of the servo motor speed is [mm/s].
[Pr. PB28_Gain switching time constant (CDT)]
Set the time constant until the gain switches in response to the conditions set in [Pr. PB26 Gain switching function] and [Pr.
PB27 Gain switching condition].
[Pr. PB29_Load to motor inertia ratio/load to motor mass ratio
after gain switching (GD2B)]
Set the load to motor inertia ratio for when the gain switching is enabled.
The setting value of this servo parameter is enabled when [Pr. PA08.0 Gain adjustment mode selection] is set to "3" (manual
mode).
[Pr. PB30_Position control gain after gain switching (PG2B)]
Set the position control gain for when the gain switching is enabled.
When the setting value of this servo parameter is less than "1.0", the setting value of [Pr. PB08 Position control gain] is
applied.
The setting value of this servo parameter is enabled when [Pr. PA08.0 Gain adjustment mode selection] is set to "3" (manual
mode).
[Pr. PB31_Speed control gain after gain switching (VG2B)]
Set the speed control gain for when the gain switching is enabled.
When the setting value of this servo parameter is less than "20", the setting value of [Pr. PB09 Speed control gain] is applied.
The setting value of this servo parameter is enabled when [Pr. PA08.0 Gain adjustment mode selection] is set to "3" (manual
mode).
