Startup
Pxxx controller parameters
Pxxx speed control
Speed control only parameter set 1.
The setting of all parameters important for speed control is supported by the startup
functions of the startup manager. Direct alterations to individual controller parameters
are reserved for optimization by specialists.
P-gain speed
controller
Gain factor of the P-component of the speed controller.
Time constant
speed controller
Integration time constant of the speed controller. The I-component reacts inversely pro-
portionate to the time constant. A large numerical value results in a small I-component,
although 0 = no I-component.
Filter speed actual
value
Filter time constant of the actual speed value filter.
Speed setpoint
filter
Speed ramp will be filtered, graduated setpoint entry or interfering impulse at analog out-
put can be smoothed.
Filter acceleration
precontrol
Filter time constant of acceleration precontrol. This constant influences the control re-
sponse of the speed controller. The differentiator is programmed.
P-gain position
controller
Setting value for the P controller of the position control loop.
Amplification
acceleration pre-
control
Amplification factor of acceleration precontrol. This factor improves the control response
of the speed controller.
PWM frequency
Setting the PWM frequency.
