DC Stop
The motor is held with a DC current (
2-01 DC
Brake Current
) for a specified time (
2-02 DC
Braking Time
).
•
DC brake is activated in
2-03 DC Brake Cut-
in Speed [RPM]
and a stop command is
active.
•
DC brake (inverse) is selected as a function
for a digital input (parameter group
5–1*
Digital Inputs
). The corresponding terminal
is not active.
•
The DC brake is activated via serial
communication.
Feedback high
The sum of all active feedbacks is above the
feedback limit set in
4-57 Warning Feedback
High
.
Feedback low
The sum of all active feedbacks is below the
feedback limit set in
4-56 Warning Feedback
Low
.
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 Slow.
•
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 adjustable frequency drive saves the
actual reference. Changing the reference is
now only possible via terminal functions
Speed Up and Slow.
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 adjustable
frequency drive, a permanent test current is
applied to the motor.
Over Voltage
Control (OVC)
Overvoltage
control was activated in
2-17 Over-
voltage Control
,
[2] Enabled
. The connected
motor is supplying 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.
PowerUnit Off
(Only adjustable frequency drives with an
external 24 V power supply installed).
Line power supply to the adjustable frequency
drive 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 chosen 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 adjustable frequency drive 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 adjustable frequency drive drives the
motor.
