DC Voltage U0
In par. H-41 Motor Control Principle U/f and in par. H-80 Function at Stop DC Voltage U0 is selected. A Stop command (e.g. Stop (inverse)) is activated. The voltage
selected according to the par. H-55 U/f Characteristic - U [0] (UF Characteristic – U[V]) is applied to the motor.
Feedback high
In par. H-77 Warning Feedback High, an upper feedback limit is set. The sum of all active feedbacks is above the feedback limit.
Feedback low
In par. H-76 Warning Feedback Low, a lower feedback limit is set. The sum of all active feedbacks is below the feedback limit.
Flying start
In par. H-09 Start Mode, the Flying start function is activated. The drive is testing if the connected motor is running with a speed that is in the adjusted speed range.
The process was started by connecting a digital input (parameter group E-##) programmed as Coast inverse or by connecting to mains.
Freeze output
The remote reference is active and the momentarily given speed is saved.
1.
Freeze output was selected as a function for a digital input (Group E-##). The corresponding terminal is active. Speed control is only possible via the
terminal functions Speed up and Speed down.
2.
Hold ramp is activated via serial communication.
Freeze output request
A freeze output command has been given, but the motor will remain stopped until a Run permissive signal is received via a digital input.
Freeze Ref.
Freeze Ref. was chosen as a function for a digital input (parameter group E-##). The corresponding terminal is controlled. The drive saves the actual reference.
Changing the reference is now only possible via terminal functions Speed up and Speed down.
Jog request
A JOG command has been given, but the motor will be stopped until a Run permissive signal is received via a digital input.
Jogging
The motor is running with par. C-21 Jog Speed [RPM].
1.
Jog was selected as function for a digital input (parameter group E-##). The corresponding terminal (e.g. Terminal 29) is active.
2.
The Jog function is activated via the serial communication.
3.
The Jog function was selected as a reaction for a monitoring function (e.g. No signal). The monitoring function is active.
Kinetic backup
In par. SP-10 Line failure, a function was set as kinetic backup. The Mains Voltage is below the value set in par. SP-11 Line Voltage at Input Fault. The drive is running
the motor momentarily with kinetic energy from the inertia of the load.
Motor check (AF-600 FP)
In par. H-80 Function at Stop, the function Motor check was selected. A stop command (e.g. Stop inverse) is active. To ensure that a motor is connected to the
drive, a permanent test current is applied to the motor.
Off1
PROFIDrive profile was selected in par. O-10 Control Word Profile. The OFF 1 function is activated via serial communication. The motor is stopped via the ramp.
Off2
PROFIDrive profile was selected in par. O-10 Control Word Profile. The OFF 2 function is activated via serial communication. The output of the drive is disabled
immediately and the motor coasted.
Off3
PROFIDrive profile was selected in par. O-10 Control Word Profile. The OFF 3 function is activated via serial communication. The motor is stopped via the ramp.
OVC control
Overvoltage Control is activated in par. B-17 Over-voltage Control. The connected motor is supplying the drive with generative energy. The Overvoltage Control
adjusts the UF ratio to run the motor in controlled mode and to prevent the drive from tripping.
PowerUnit Off
Only with frequency converters with installed option (ext. 24 V supply). The mains supply to the frequency converter is cut off, but the control card is still supplied
with 24 V.
Pre-magnetize
Pre-magnetization is selected in par. H-80 Function at Stop. A stop command (e.g. Stop inverse) is activated. A suitable constant magnetizing current is applied
to the motor.
