Remote
The speed reference is given from
•
External signals.
•
Serial communication.
•
Internal preset references.
Local
The drive uses reference values from the LCP.
Table 8.2 Reference Site
AC brake
AC brake was selected in
parameter 2-10 Brake
Function
. The AC brake overmagnetizes the
motor to achieve a controlled slowdown.
AMA finish OK
Automatic motor adaptation (AMA) was
carried out successfully.
AMA ready
AMA is ready to start. To start, press [Hand
On].
AMA running
AMA process is in progress.
Braking
The brake chopper is in operation. The brake
resistor absorbs the generative energy.
Braking max.
The brake chopper is in operation. The power
limit for the brake resistor defined in
parameter 2-12 Brake Power Limit (kW)
has
been reached.
Coast
•
[2] Coast inverse
was selected as a function
for a digital input (
parameter group 5-1*
Digital Inputs
). The corresponding terminal
is not connected.
•
Coast activated by serial communication.
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
at mains fault.
•
The drive ramps down the motor using a
controlled ramp down.
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 Braking
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 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
parameter 4-57 Warning
Feedback High
.
Feedback low
The sum of all active feedbacks is below the
feedback limit set in
parameter 4-56 Warning
Feedback Low
.
Freeze output
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
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.
[19] Freeze Reference
was selected as a
function for a digital input (
parameter group
5-1* Digital Inputs
). The corresponding 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.
