Explanation of the parameters
Parameters
P2xx Controller parameters
P20x Speed con-
trol
Speed control only in parameter set 1.
The speed controller of the MOVIDRIVE
®
is a PI-controller and is active when the
following operating modes are set:
•
All operating modes with VFC-n-CONTROL.
•
CFC operating modes: The speed controller is only active in “CFC & M-CONTROL“
when speed limiting is active (P70x Operating modes).
•
Servo operating modes: The speed controller is only active in “SERVO & M-CON-
TROL“ when speed limiting is active (P70x Operating modes).
The setting of all parameters relevant for speed control is supported by the SHELL
startup functions or the DBG11B keypad (VFC only). Direct alterations to individual
controller parameters are reserved for optimization by specialists.
P200 P gain speed
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
proportionate to the time constant, i.e. a large numerical value results in a small I-com-
ponent, although 0 = no I-component.
P202 Gain acceler-
ation feedforward
Setting range: 0 ... 65
Gain factor of acceleration feedforward. This parameter improves the control response
of the speed controller.
P203 Filter accel-
eration feedfor-
ward
Setting range: 0 ... 100 ms
Filter time constant of the acceleration precontrol. This constant influences the control
response of the speed controller. The differentiator has a fixed program setting.
P204 Filter speed
actual value
Setting range: 0 ... 32 ms
Filter time constant of the actual speed value filter.
