Parameter 2-26 Torque Ref to parameter 2-33 Speed PID Start Lowpass Filter Time are only available for the hoist mechanical brake
control (flux with motor feedback).
5.3.4 2-3* Adv. Mech Brake
Parameter 2-30 Position P Start Proportional Gain to parameter 2-33 Speed PID Start Lowpass Filter Time can be set up for very smooth
transition change from speed control to position control during parameter 2-25 Brake Release Time - the time when the load is trans-
ferred from the mechanical brake to the drive. Parameter 2-30 Position P Start Proportional Gain to parameter 2-33 Speed PID Start
Lowpass Filter Time are activated when parameter 2-28 Gain Boost Factor is set to 0. See
Illustration 46 for more information.
Parameter 2-30 Position P Start Proportional Gain
Table 178: Parameter 2-30 Position P Start Proportional Gain
2-30 Position P Start Proportional Gain
Default value: X0.0500
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 amplifi-
cation is too high, the process may become unstable.
Parameter 2-31 Speed PID Start Proportional Gain
Table 179: Parameter 2-31 Speed PID Start Proportional Gain
2-31 Speed PID Start Proportional Gain
Default value: 0.0500
Parameter type: Range, 0.0000 - 1.0000
Setup: All setups
Conversion index: -4
Data type: Uint32
Change during operation: True
Enter the speed controller proportional gain during start. Quick control is obtained at high amplification. However, if amplification is
too high, the process may become unstable.
