The remote reference is active, which holds the present speed.
• Freeze output was selected as a function for a digital input (parameter group
5-1* Digital Inputs). The corresponding terminal is active. Speed control is
only possible via the terminal functions Speed Up and Slow.
• Hold ramp is activated via serial communication.
A freeze output command was given but the motor remains stopped until a run
permissive signal is received.
Freeze Reference was selected as a function for a digital input (parameter group
5-1* Digital Inputs). The corresponding terminal is active. The adjustable
frequency drive saves the actual reference. Changing the reference is now only
possible via terminal functions Speed Up and Slow.
A jog command was given but the motor remains stopped until a run permissive
signal is received via a digital input.
The motor is running as programmed in 3-19 Jog Speed [RPM].
• Jog was selected as function for a digital input (parameter group 5-1* Digital
Inputs). The corresponding terminal (e.g., Terminal 29) is active.
• The Jog function is activated via the serial communication.
• The Jog function was selected as a reaction for a monitoring function (e.g.,
No signal). The monitoring function is active.
In 1-80 Function at Stop, Motor Check was selected. A stop command is active.
To ensure that a motor is connected to the adjustable frequency drive, a
permanent test current is applied to the motor.
Overvoltage control was activated in 2-17 Overvoltage Control, [2] Enabled. The
connected motor supplies the adjustable frequency drive with generative energy.
The overvoltage control adjusts the V/Hz ratio to run the motor in controlled
mode and to prevent the adjustable frequency drive from tripping.
(Only adjustable frequency drives with an external 24 V power supply installed).
Line power supply to the adjustable frequency drive was removed, and the
control card is supplied by the external 24 V.
Protection mode is active. The unit has detected a critical status (overcurrent or
overvoltage).
• To avoid tripping, switching frequency is reduced to 4 kHz.
• If possible, protection mode ends after approximately 10 s.
• Protection mode can be restricted in 14-26 Trip Delay at Inverter Fault.
The motor is decelerating using 3-81 Quick Stop Ramp Time.
• Quick stop inverse was selected as a function for a digital input (parameter
group 5-1* Digital Inputs). The corresponding terminal is not active.
• The quick stop function was activated via serial communication.
The motor is accelerating/decelerating using the active Ramp-Up/Down. The
reference, a limit value, or a standstill is not yet reached.
The sum of all active references is above the reference limit set in 4-55 Warning
Reference High.
The sum of all active references is below the reference limit set in 4-54 Warning
Reference Low.
A start command was given but the motor remains stopped until a run
permissive signal is received via digital input.
The motor is driven by the adjustable frequency drive.
The energy-saving function is enabled. The motor has stopped but restarts
automatically when required.
Motor speed is above the value set in 4-53 Warning Speed High.
