CPI.CPC
(Default: -0.333333
= 30[ASG] )
XC
Current actual value (with sign)
CAV.YC

CPI.XC
CLU
Limit of the current-dependent inverter stability limit [

CPI.CLU
(Default: 150.0)
ALU
Inverter control limit of the firing angle [
°
]
the minimum of CLU and ALU is used
(Initialization connection/
default: 150.0)
ALL
Rectifier control limit of the firing angle [
°
]
(Initialization connection/
default: 30.0)
SV
Setting value for torque reversal or continuous tracking
(only active for S = 1)
(SV corresponds to the torque reversal of the motor EMF)
