The remote reference is active, which holds
the present speed.
•
Freeze output was selected as a function
for a digital input. The corresponding
terminal is active. Speed control is only
possible via the terminal functions speed
up and speed down.
•
Hold ramp is activated via serial communi-
cation.
A freeze output command has been given, but
the motor remains stopped until a run
permissive signal is received.
Freeze Reference was selected as a function for
a digital input. The corresponding terminal is
active. The frequency converter saves the
actual reference. Changing the reference is
now only possible via terminal functions
speed up and speed down.
A jog command has been given, but the
motor remains stopped until a run permissive
signal is received via a digital input.
The motor is running as programmed in
parameter C-21 Jog Speed [RPM].
•
Jog was selected as function for a digital
input. The corresponding terminal is active.
•
The jog function is activated via the serial
communication.
•
The jog function was selected as a reaction
for a monitoring function. The monitoring
function is active.
Overvoltage control was activated in
parameter B-17 Over-voltage Control, [2]
Enabled. The connected motor supplies the
frequency converter with generative energy.
The overvoltage control adjusts the V/Hz ratio
to run the motor in controlled mode and to
prevent the frequency converter from tripping.
(Only frequency converters with a 24 V
external supply installed).
Mains supply to the frequency converter is
removed, but the control card is supplied by
the external 24 V.
Protection mode is active. The unit has
detected a critical status (an overcurrent or
overvoltage).
•
To avoid tripping, the switching frequency
is reduced to 4 kHz.
•
If possible, protection mode ends after
approximately 10 s.
•
Protection mode can be restricted in
parameter SP-26 Trip Delay at Drive Fault.

The motor is decelerating using
parameter C-23 Quick Stop Decel Time.
•
Quick stop inverse was selected as a
function for a digital input. 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 parameter H-75 Warning
Reference High.
The sum of all active references is below the
reference limit set in parameter H-74 Warning
Reference Low.
The frequency converter is running in the
reference range. The feedback value matches
the setpoint value.
A start command has been given, but the
motor is stopped until a run permissive signal
is received via digital input.
The frequency converter drives the motor.
The energy saving function is enabled. The
motor has stopped, but restarts automatically
when required.
Motor speed is above the value set in
parameter H-73 Warning Speed High.
Motor speed is below the value set in
parameter H-72 Warning Speed Low.
In Auto mode, the frequency converter starts
the motor with a start signal from a digital
input or serial communication.
In parameter F-24 Holding Time, a delay
starting time was set. A start command is
activated and the motor starts after the start
delay time expires.
Start forward and start reverse were selected
as functions for 2 different digital inputs. The
motor starts in forward or reverse depending
on which corresponding terminal is activated.
The frequency converter has received a stop
command from the keypad, digital input, or
serial communication.
An alarm occurred and the motor is stopped.
Once the cause of the alarm is cleared, the
frequency converter can be reset manually by
pressing [Reset] or remotely by control
terminals or serial communication.
