Maintenance, Diagnostics, a...
Jogging The motor is running as programmed in
parameter 3-19 Jog Speed [RPM].
•
[14] Jog was selected as function for a
digital input (parameter group 5-1* Digital
Inputs). The corresponding terminal (for
example, 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 (for example, No
signal). The monitoring function is active.
Motor check In parameter 1-80 Function at Stop, [2] Motor
Check was selected. A stop command is active.
To ensure that a motor is connected to the
drive, a permanent test current is applied to
the motor.
OVC control Overvoltage control was activated in
parameter 2-17 Over-voltage Control, [2]
Enabled. The connected motor is supplying
the drive with generative energy. The
overvoltage control adjusts the V/Hz ratio to
run the motor in controlled mode and to
prevent the drive from tripping.
Power unit off (For drives with a 24 V DC external supply
installed only.) Mains supply to the drive is
removed, but the control card is supplied by
the 24 V DC external supply.
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 1500 kHz if
parameter 14-55 Output Filter is set to [2]
Sine-Wave Filter Fixed. Otherwise, the
switching frequency is reduced to 1000 Hz.
•
If possible, protection mode ends after
approximately 10 s.
•
Protection mode can be restricted in
parameter 14-26 Trip Delay at Inverter Fault.
QStop The motor is decelerating using
parameter 3-81 Quick Stop Ramp Time.
•
[4] 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.

The sum of all active references is above the
reference limit set in parameter 4-55 Warning
Reference High.
The sum of all active references is below the
reference limit set in parameter 4-54 Warning
Reference Low.
The drive 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 drive is driving the motor.
The energy saving function is enabled. This
function being enabled means that now the
motor has stopped, but that it restarts
automatically when required.
The motor speed is above the value set in
parameter 4-53 Warning Speed High.
The motor speed is below the value set in
parameter 4-52 Warning Speed Low.
In auto-on mode, the drive starts the motor
with a start signal from a digital input or serial
communication.
In parameter 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.
[12] Enable Start Forward and [13] Enable 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.
The drive has received a stop command from
1 of the following:
•
LCP.
•
Digital input.
•
Serial communication.
An alarm occurred and the motor is stopped.
Once the cause of the alarm is cleared, reset
the drive using 1 of the following:
•
Pressing [Reset].
•
Remotely by control terminals.
•
Via serial communication.
Pressing [Reset] or remotely by control
terminals or via serial communication.
