Operating Instructions
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.
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 (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.
A jog command has been given, but the
motor is 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 frequency
converter, a permanent test current is applied
to the motor.
Overvoltage control was activated in
2-17 Over-voltage Control. The connected
motor is supplying 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.
(For frequency converters with an external 24
V power supply installed only). 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, 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.
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 motor is driven by the frequency
converter.
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.
Trip 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.
Trip lock An alarm occurred and the motor is stopped.
Once the cause of the alarm is cleared, power
must be cycled to the frequency converter.
The frequency converter can then be reset
manually by pressing [Reset] or remotely by
control terminals or serial communication.
