I/O
CPI.
AD Hardware address
WC Current setpoint (absolute value)
CPC Pre-control angle in the discontinuous range
XC Current actual value (with sign)
CLU Limit of the current-dependent inverter stability limit [ ° ],
if this function is not required, CLU=ALU should be set to 150 [°].
ALU Inverter control limit of the firing angle [ ° ]
the minimum of CLU and ALU is used
ALL Rectifier control limit of the firing angle [ ° ]
SV Setting value for torque reversal or continuous tracking
(only active for S = 1)
(SV corresponds to the torque reversal of the motor EMF)
ILU Integrator inhibit, positive direction
ILL Integrator inhibit, negative direction
S Sets the integrator with the value SV
SVC
Mode: Pre-control of the CPI
KP Proportional gain [1]
TN Integral action time [ms]
PC Inhibits integrator component
(with PC=1 ⇒ integrator is deleted)
EN Controller enable
(with EN=0, all Yxx are immediately set to zero)

Y Firing angle [ASG]
YE
System deviation
YWP Pre-control angle [ASG]
YP P component
YI I component
QU Controller at its positive limit (M1)
QL Controller at its negative limit (M2)
TA Sampling time: Current controller (configured)
YW Firing angle [ ° ]
(same as Y, only in another format)
ZSU Inverter control limit, effective [ ° ]
(internally used limit f (ALU,CLU) is displayed)
ZSL Rectifier control limit, effective [ ° ]
(ALL limit is displayed)
