Variable proportional/integral factor (speed)
The proportional and integral factor can be changed speed-dependent in order to
achieve a higher standstill rigidity.
The total proportional factor is made up of:
KP
total
= KP
base
+ KP
var
KP
base
= cs01
KP
var
changes between cs08 speed for max. kp/ki and cs09 speed for normal kp/ki
from value cs06 variable kp speed offset to 0.
Maximum KP = KP
base
* (1 + cs06)
The total integral factor is made up of:
KI
total
= KI
base
+ KI
var
KI
base
= cs01 / cs05
KI
var
changes between cs08 speed for max. kp/ki and cs09 speed for normal kp/ki
from value cs07 variable ki speed offset to 0.
Maximum KI = KI
base
* (1 + cs07)

Figure 99: Variable proportional factor (kp) / integral factor (ki) with cs08=10%,
cs09=20%
Example:
n
rated
= 2000rpm
cs08 = 10% => n
for max KP,KI
= 200rpm cs09 = 20% => n
for min KP, KI
= 400rpm
cs01 KP speed [%Mn/rpm] = 1
cs05 Tn speed = 20ms = 0.02 s
=> Ki
Base
cs01 / cs05 = 50% M
rated
/(rpm * s)
cs07 = 150% => (1 + cs07) = 2.5
KI = 125% M
rated
/(rpm * s) to 200rpm
KI = 87.5% M
rated
/(rpm * s) at 300rpm
KI = 50% M
rated
/(rpm * s) from 400rpm
cs01 KP speed [%Mn/rpm] = 1
cs06 = 100% => (1 + cs06) = 2
KP = 2% M
rated
/rpm to 200rpm
KP = 1.5% M
rated
/rpm at 300rpm
KP = 1% M
rated
/rpm from 400rpm
