Value/meaning
wDriveControlStatus
WORD
Status word of the controller
• The status word contains information on the currents status of the drive
controller.
• For bit assignment, see subchapter " wDeviceStatusWord status word " in the
chapter for device control.
wStateDetermFailNoLow
WORD
Display of the status determining error (LOW word)
wStateDetermFailNoHigh
WORD
Display of the status determining error (HIGH word)
bDriveFail
BOOL
TRUE Drive controller in error status.
• " Fault " device status is active.
bDriveReady
BOOL
TRUE Controller is ready for operation.
• " SwitchedOn " device status is active.
• The drive is in this device status if the DC bus voltage is applied
and the controller is still inhibited by the user (controller inhibit).
bCInhActive
BOOL
TRUE Controller inhibit is active.
bQSPIsActive
BOOL
TRUE Quick stop is active.
bSpeedCcw
BOOL
Current direction of rotation
FALSE Clockwise rotation (Cw)
TRUE Direction of rotation to the left (Ccw)
bSpeedActCompare
BOOL
Result of the speed comparison (detection of speed=0)
TRUE During open-loop operation:
Speed setpoint < Comparison value ( C00024 )
During closed-loop operation:
Actual speed value < Comparison value ( C00024 )
bOverLoadActive
BOOL
In preparation (output is not interconnected on the application level)
bUnderLoadActive
BOOL
In preparation (output is not interconnected on the application level)
bImaxActive
BOOL
"Current setpoint inside the limitation" status signal
TRUE The current setpoint is internally limited (the drive controller
operates at the maximum current limit).
bSpeedSetReached
BOOL
Status signal "setpoint = 0"
TRUE Speed setpoint from the ramp function generator = 0
bSpeedActEqSet
BOOL
TRUE Actual speed value = speed setpoint
nMotorCurrent_a
INT
Current stator current/effective motor current
• Scaling: 16384 ≡ 100 % I
max_mot
( C00022 )
nMotorSpeedSet_a
INT
Speed setpoint
• Scaling: 16384 ≡ 100 % reference speed ( C00011 )
nMotorSpeedAct_a
INT
Actual speed value
• Scaling: 16384 ≡ 100 % reference speed ( C00011 )
nMotorTorqueAct_a
INT
Actual torque
• In the "VFC (+encoder)" operating mode of the motor control, this value is
determined from the current motor current and corresponds to the actual torque
only by approximation.
• Scaling: 16384 ≡ 100 % M
