Operation
status
Description
AMA ready
AMA is ready to start. To start, press [Hand On].
AMA run-
ning
AMA process is in progress.
Braking
The brake chopper is in operation. The brake resistor absorbs the generative energy.
Coast
[2] Coast inverse
was selected as a function for a digital input (
parameter group 5–1* Digital Inputs
). The corre-
sponding terminal is not connected.
Coast activated by serial communication.
No output from the drive to the motor.
Ctrl. ramp-
down
[1] Ctrl. ramp-down
was selected in
parameter 14-10 Mains Failure
.
The mains voltage is below the value set in
parameter 14-11 Mains Voltage at Mains Fault
.
The drive ramps down the motor in a controlled manner.
Current
high
The drive output current is above the limit set in
parameter 4-51 Warning Current High
.
Current low
The drive output current is below the limit set in
parameter 4-52 Warning Speed Low
.
DC hold
DC hold is selected in
parameter 1-80 Function at Stop
and a stop command is active. The motor is held by a DC
current set in
parameter 2-00 DC Hold Current
.
DC stop
The motor is held with a DC current (
parameter 2-01 DC Brake Current
) for a specified time (
parameter 2-02 DC Brak-
ing Time
).
DC brake is activated in
parameter 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 corre-
sponding terminal is not active.
The DC brake is activated via serial communication.
Feedback
high
The sum of all active feedback is above the feedback limit set in
parameter 4-57 Warning Feedback High
.
Feedback
low
The sum of all active feedback is below the feedback limit set in
parameter 4-56 Warning Feedback Low
.
Freeze out-
put
The remote reference is active, which holds the present speed.
[20] Freeze Output
was selected as a function for a digital input (
parameter group 5–1* Digital Inputs
). The corre-
sponding terminal is active. Speed control is only possible via the terminal functions speed up and speed
down.
Hold ramp is activated via serial communication.
Freeze out-
put request
A freeze output command has been given, but the motor remains stopped until a run permissive signal is re-
ceived.
Freeze ref.
[19] Freeze Reference
was selected as a function for a digital input (
parameter group 5–1* Digital Inputs
). The corre-
sponding terminal is active. The drive 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 is stopped until a run permissive signal is received via a digital
input.
Jogging
The motor is running as programmed in
parameter 3-19 Jog Speed [RPM]
.
