bSpeedActCompare
BOOL
Result of the speed comparison
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
max
( C00057 )
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
bBrakeReleaseOut
BOOL
Holding brake control : Trigger signal for the holding brake control switching
element via a digital output
• Use bit 0 in C02582 to activate inverted switching element triggering.
FALSE Apply brake.
TRUE Release brake.
bBrakeReleased
BOOL
Holding brake control : Status signal of the brake control with regard to the release
and application times of the brake
FALSE Brake applied (after the brake application time has expired).
TRUE Brake released (after the brake release time has expired).
