Edition 06.2002
CPI. Significance Value\connection
AD
Hardware address
WC
Current setpoint (absolute value)
CSP.YCW
→ CPI.WC
CPC Pre-control angle in the discontinuous range
CPC.Y
→ 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 [°],
if this function is not required, CLU=ALU should be set to 150 [°].
CAV.YAU
→ 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)
SOL.YSV
→ CPI.SV
{>-1
…+1<}
ILU
Integrator inhibit, positive direction
CSP.QIU
→ CPI.ILU
(Default: 0)
ILL
Integrator inhibit, negative direction
CSP.QIL
→ CPI.ILL
(Default: 0)
S
Sets the integrator with the value SV
SOL.QCS
→ CPI.S
SVC
Mode: Pre-control of the CPI (Default: 0)
KP
Proportional gain [1] (Default: 0.01)
TN
Integral action time [ms] (Default: 10000 ms)
PC
Inhibits integrator component
(with PC=1
⇒ integrator is deleted)
(Default: 0)
EN
Controller enable
(with EN=0, all Yxx are immediately set to zero)
SOL.QCE
→ CPI.EN

Y
Firing angle [ASG]
CPI.Y
→ PC6.WAS
(Default: 0.0)
YE
System deviation XCWCYE −=

YW Firing angle [°]
(same as Y, only in another format)
(Default: 0.0)
ZSU Inverter control limit, effective [°]
(internally used limit f (ALU,CLU) is displayed)
(Default: 0.0)
ZSL Rectifier control limit, effective [°]
(ALL limit is displayed)
