11.7.1 Velocity
The maximum speed per minute for positioning is defined here. The speed is measured via the rotary encoder (0
... 10000 rpm). If there is a transmission between the motor and the rotary encoder (e.g. by a gear or a spin-
dle), the transmission ratio must be taken into account for the number of revolutions.
EXAMPLE:

Demanded motor speed rpm = 3000

Gearing ratio i = 10
V = UPM/i = 3000/10 = 300
11.7.2 Acceleration
The acceleration during positioning in revolutions per second squared (
] [
] [
2
s
U
) is set in this parameter.
11.7.3 Pulse Encoder
The number of pulses of the measuring system per revolution of the motor is set here in order to be able to cal-
culate the nominal speed (maximum 9999 pulses per revolution).
11.7.4 P-Portion
Proportional amplification: setting range 1 … 3000
General:
The P-element consists exclusively of a proportional part and thus has an amplifying property.
The P-component multiplies the input value by a constant factor.
P40T:
In case of control deviation, the difference between target and actual value is multiplied by the value set here
and output as a voltage component. The higher the proportional amplification, the more sensitive (possibly also
unstable) the control loop becomes.
