Freeze output 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
Speed Down.
•
Hold ramp is activated via serial communi-
cation.
Freeze output
request
A freeze output command has been given,
but the motor remains stopped until a run
permissive signal is received.
Freeze ref.
Freeze Reference was selected as a function for
a digital input (parameter group 5-1* Digital
Inputs). 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.
Jog request A jog command has been given, but the
motor remains stopped until a run permissive
signal is received via a digital input.
Jogging 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 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.
Motor check
In 1-80 Function at Stop, Motor Check was
selected. A stop command is active. To ensure
that a motor is connected to the frequency
converter, a permanent test current is applied
to the motor.
OVC control
Overvoltage control was activated in 2-17 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.
Power Unit Off (Only frequency converters with an 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 md 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
14-26 Trip Delay at Inverter Fault.
QStop
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.
Ramping The motor is accelerating/decelerating using
the active ramp up/down. The reference, a
limit value, or a standstill is not yet reached.
Ref. high The sum of all active references is above the
reference limit set in 4-55 Warning Reference
High.
Ref. low The sum of all active references is below the
reference limit set in 4-54 Warning Reference
Low.
Run on ref. The frequency converter is running in the
reference range. The feedback value matches
the setpoint value.
Run request A start command has been given, but the
motor is stopped until a run permissive signal
is received via digital input.
Running The frequency converter drives the motor.
Sleep Mode The energy saving function is enabled. The
motor has stopped, but restarts automatically
when required.
Speed high Motor speed is above the value set in
4-53 Warning Speed High.
Speed low Motor speed is below the value set in
4-52 Warning Speed Low.
Standby In Auto On mode, the frequency converter
starts the motor with a start signal from a
digital input or serial communication.
Start delay
In 1-71 Start Delay, a delay starting time was
set. A start command is activated and the
motor starts after the start delay time expires.
Start fwd/rev Start forward and start reverse were selected
as functions for 2 different digital inputs
(parameter group 5–1* Digital Inputs). The
motor starts in forward or reverse depending
on which corresponding terminal is activated.
Stop The frequency converter has received a stop
command from the LCP, digital input, or serial
communication.
