6.1.3.1 Analogue Parameters

Velocity
The maximum speed is set in this parameter, in rpm. Should there be gearing between the motor
and the measuring system, this has to be considered in the calculations (e.g. gear or spindle)
Example!
Demanded (below the maximum possible !)
motor speed rpm = 3000
Gearing ratio i = 10
V = rpm/i = 3000 rpm/10 = 300 rpm
Acceleration
The acceleration during positioning is set in this parameter in revolutions per square second (

Also here you have to consider possible gearing ratio.
P-Portion
Proportional amplification: setting range 1 ... 99999
General:
The P-controller exclusively consists of a proportional portion and has thereby its reinforcing
characteristic. The P-term multiplies the input value with a constant coefficient.
P40:
At offset the difference between the target and actual value is multiplied with the entered value and
shown as power-sharing. The bigger the proportional amplification the more sensitive the control
loop will be (possibly even unstable).
I-portion / I-Limit
Integral step: setting range 1 ... 99999
General:
An I-controller (integrating controller) determines the control value through timed integration of the
offset taking the reset time into account. A continuing offset leads to further increase of the analogue
output. The reset time determines how big the temporal influence is. The maximum reset time is
limited through I-limit. The step response of the I-portion is a linear increase. That means for a
constant offset the integral will be increased and thus reinforces the I-portion.
P40:
At offset the analogue control voltage will continue to increase step by step until there is zero
difference between the target and actual position and the entered I-limit in this parameter is reached
respectively. The greater the I-portion, the slower is the response.
