Set the Gain Boost Factor.
2-29 Torque Ramp Down Time
Default value: 0.0 s Parameter type: Range (0.0–5.0 s)
Setup: All setups Conversion index: -1
Data type: Uint8 Change during operation: True
Set the torque ramp-down time.
4.3.4 2-3* Adv. Mech Brake
2-30 Position P Start Proportional Gain
Default value: 0.0000 Parameter type: Range (0.0000–1.0000)
Setup: All setups Conversion index: -4
Data type: Uint32 Change during operation: True
Enter the position controller during start proportional gain. Quick control is obtained at high amplification. However, if the amplification
is large, the process may become unstable.
2-31 Speed PID Start Proportional Gain
Default value: 0.015 Parameter type: Range (0.000 = Off–1.000)
Setup: All setups Conversion index: -3
Data type: Uint32 Change during operation: True
Enter the position controller during start proportional gain. Quick control is obtained at high amplification. However, if the amplification
is large, the process may become unstable.
2-32 Speed PID Start Integral Time
Default value: 200.0 ms Parameter type: Range (1.0 ms–20000.0 = Off
ms)
Setup: All setups Conversion index: -1
Data type: Uint32 Change during operation: True
Enter the speed controller integral time. Obtain quick control through a short integral time, if the integral time is short, the process
becomes unstable. An excessively long integral time disables the integral action.
2-33 Speed PID Start Lowpass Filter Time
Default value: 10.0 ms Parameter type: Range (0.1–100.0 ms)
Setup: All setups Conversion index: -1
Data type: Uint16 Change during operation: True
Set a time constant for the speed control low-pass filter. The low-pass filter improves steady-state performance and dampens oscillations
on the feedback signal. However, severe filtering can be detrimental to dynamic performance.
