bDriveReady
BOOL
TRUE Controller is ready for operation.
• "
" 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 (
During closed-loop operation:
Actual speed value < Comparison value (
)
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
nMotorCurrent_a
INT
Current stator current/effective motor current
• Scaling: 16384 ≡ 100 % I
max_mot
)
nMotorSpeedSet_a
INT
Speed setpoint
• Scaling: 16384 ≡ 100 % reference speed (
nMotorSpeedAct_a
INT
Actual speed value
• Scaling: 16384 ≡ 100 % reference speed (
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
max
nDCVoltage_a
INT
Actual DC-bus voltage
• Scaling: 16384 ≡ 1000 V
nMotorVoltage_a
INT
Current motor voltage/inverter output voltage
• Scaling: 16384 ≡ 1000 V
MCK basic functions
bMBrakeReleaseOut
BOOL
: Trigger signal for the holding brake control switching
element via a digital output
• Use bit 0 in
to activate inverted switching element triggering.
FALSE Apply brake.
TRUE Release brake.
bMBrakeReleased
BOOL
: "Brake released" considering the brake release time
• When the holding brake is triggered to close, bMBrakeReleased is immediately set
to FALSE even if the brake closing time has not yet elapsed!
TRUE Brake released (after the brake release time has expired).
wMckState1
wMckState2
WORD
Output of the MCK status words
• For a detailed description of each status bit see chapter "
".
wMckActOperationMode
WORD
Active setpoint-generating state of the MCK.
• Bits B0 ... B3 contain the information of the
