Explanation of the parameters
Parameterization of MOVIPRO
®
The setting of all parameters important for speed control is supported by the startup
functions of MOVITOOLS
®
MotionStudio. Direct alterations to individual controller pa-
rameters are reserved for optimization by specialists.
P200 P-gain n-
controller
Setting range: 0,01 – 2 – 32
Gain factor of the P-component of the speed controller.
P201 Time con-
stant n-controller
Setting range: 0 – 10 – 3000 ms (0 = no I-component)
Integration time constant of the speed controller The I-component reacts inversely pro-
portionate to the time constant, i.e. a large numerical value results in a small I-compo-
nent, although 0 = no I-component.
P202 Gain acceler-
ation precontrol
Setting range: 0 – 65
Amplification factor of acceleration precontrol. This parameter improves the control re-
sponse of the speed controller.
P203 Filter accel-
eration precontrol
Setting range: 0 – 100 ms
Filter time constant of acceleration precontrol. This constant influences the control re-
sponse of the speed controller. The differentiator is programmed.
P204 Filter actual
speed value
Setting range: 0 – 32 ms
Filter time constant of the actual speed value filter.
P205 Load precon-
trol CFC
Load precontrol CFC is only effective in CFC and servo operating modes.
Setting range: –150 – 0 – 150 %
This parameter determines the initial value of the torque setpoint upon enable. The pa-
rameter must be set if increased starting torque is required when the drive is enabled.
For example, a setting greater than 0 % makes it possible to prevent the unwanted sag-
ging of hoists when the brake is released. This function should only be used in hoists
without counterweight.
Recommended setting: Value of the active current (page 90) when n = 0 is specified.
