bSafetyIsActive
BOOL
TRUE In preparation
bSpeedCcw
BOOL
FALSE Clockwise rotation (Cw)
TRUE Counter-clockwise rotation (Ccw)
bActSpeedEqZero
BOOL
TRUE Current speed is 0
bSpeedSetReached
BOOL
TRUE Speed setpoint reached
bSpeedActEqSet
BOOL
TRUE Actual speed value has reached the setpoint within one hysteresis
band
bNactCompare
BOOL
TRUE During open-loop operation:
Speed setpoint < comparison value ( C024 )
During closed-loop operation:
Actual speed value < comparison value ( C024 )
bImaxActive
BOOL
TRUE The current setpoint is limited internally
(the controller operates at the maximum current limit)
Motor control
bHeatSinkWarning
BOOL
TRUE Heatsink overtemperature detected
bOVDetected
BOOL
TRUE Overvoltage detected
bDcBrakeOn
BOOL
TRUE DC-injection braking active
bFlyingSyncActive
BOOL
TRUE Flying restart function is executed
nMotorFreqAct_a
C058 | INT
Current field frequency
nOutputSpeedCtrl_a
INT
Speed or slip controller output
• Scaling: 16384 ≡ 100 % reference speed ( C011 )
nMotorSpeedAct_a
C051 | INT
Actual speed value
• Scaling: 16384 ≡ 100 % reference speed ( C011 )
nMotorVoltage_a
INT
Current motor voltage/inverter output voltage
• Scaling: 16384 ≡ 1000 V
nDCVoltage_a
INT
Actual DC-bus voltage
• Scaling: 16384 ≡ 1000 V
nMotorCurrent_a
INT
Current motor current
• Scaling: 16384 ≡ 100 % I
max_mot
( C022 )
nMotorTorqueAct_a
C056/2 | INT
Actual torque
• With "VFC (+encoder)" motor control, this value is determined from the current
motor current and corresponds to the actual torque only by approximation.
