nMotorSpeedSet_a
INT
Speed setpoint
• Scaling: 16384 ≡ 100 % reference speed (C00011
)
nMotorSpeedAct_a
INT
Actual speed value
• Scaling: 16384 ≡ 100 % reference speed (C00011
)
• The absolute value is output (the sign has no meaning).
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
(C00057)
• The absolute value is output (the sign has no meaning).
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
Holding brake control: Trigger signal for the holding brake control switching
element via a digital output
•Use bit0 in C02582
to activate inverted switching element triggering.
FALSE Apply brake.
TRUE Release brake.
bMBrakeReleased
BOOL
Holding brake control: "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).
