Danfoss vlt FC 102 User Guide

Remote The speed reference is given from:
•
External signals.
•
Serial communication.
•
Internal preset references.
Local The drive system uses reference values from
the LCP.
Table 6.2 Reference Site
AC brake [2] AC brake was selected in
parameter 2-10 Brake Function. The AC brake
overmagnetizes the motor to achieve a
controlled slow down.
AMA nish OK Automatic motor adaptation (AMA) was
carried out successfully.
AMA ready AMA is ready to start. Press [Hand On] to start.
AMA running AMA process is in progress.
Braking The brake chopper is in operation. The brake
resistor absorbs the generative energy.
Braking
maximum
The brake chopper is in operation. The power
limit for the brake resistor dened in
parameter 2-12 Brake Power Limit (kW) has
been reached.
Coast
•
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] Control ramp-down was selected in
parameter 14-10 Mains Failure.
•
The mains voltage is below the value set
in parameter 14-11 Mains Fault Voltage Level
at mains fault.
•
The drive system ramps down the motor
using a controlled ramp down.
Current high The drive system’s output current is above the
limit set in parameter 4-51 Warning Current
High.
Current low The drive system’s 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
specied 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.
•
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 speed-up and speed-down terminal
functions.
•
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 drive system saves the actual reference.
Changing the reference is now only possible
via the speed-up and speed-down terminal
functions.
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 runs as programmed in
parameter 3-19 Jog Speed [RPM].
•
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.
