EMF filtering method for armature precontrol
*
0
No filtering
FDS
1
Filtering element, filter time constant = approx. 10 ms
(for use by works engineers only)
(G162)
2
Averaging over the last 2 EMF values
(for use by works engineers only )
3
Averaging over the last 3 EMF values
P164
Set armature current controller P component to zero
*
0
Set controller P component to zero (i.e. to obtain pure I
FDS
controller)
(G162)
1
Controller P component is active
P165
Select the binector to control the "Enable a torque direction for torque
*
direction change" function
BDS
(G163)
0 = Binector B0000
1 = Binector B0001
etc.
Binector status =
0 ... Enable for M0 or MII
1 ... Enable for M0 or MI

Closed-loop current control and current limitation
0
1
Closed-loop torque control with torque limitation (the
(G160)
torque setpoint is converted to a current setpoint: Current
setpoint = torque setpoint / motor flux)
Current limitation is active additionally
1
0
Closed-loop current control with torque limitation (the
specified torque limit is converted to a current limit:
Current limit = torque limit / motor flux)
Current limitation is active additionally
1
1
Do not set!
Note:
A valid field characteristic (P117=1) must be available when P169 or
P170=1. If one is not, the optimization run for field weakening (P051=27)
must be executed.
P263 determines the input quantity for the motor flux calculation.
P171
System current limit in torque direction I

BDS
The binector selected here has the same effect as parameter P170.
0 = binector B0000
(G160)
1 = binector B0001
etc.
P175
Source for variable P gain
*
FDS
The content of the selected connector acts as the P gain for the armature
(G162)
current controller after multiplication with P155.
