■
Integral time constant for velocity controller. Select from gain switching function 1 and 2.
◆
This parameter is not covered by Auto-tuning result saving.
◆
This setting is valid when Velocity Loop Proportional Control Switching Function is
invalid.
◆
Integral time is invalid (proportional control) with the setting value 1000.0ms.

0 to 15000 % 100
■
Sets Inertia moment of load device to the motor inertia moment. Select from Gain switching
function 1 or 2.
◆ If this value matches the actual mechanical system, the setting value corresponding to
Velocity Loop Proportional Gain (KVP2, KVP3, and KVP4) is response frequency of the
velocity control system.

■
Low-pass filter to eliminate high frequency element included in torque command. Select from gain
switching function 1 or 2. Sets cutoff frequency.
◆
This parameter is not covered by Auto-tuning result saving.
