Log
The
re mode log shows an overview of events related to
re mode in the re mode log, see also parameter group
18-1* Fire Mode Log.
The log includes up to 10 of the latest events. Fire Mode
Limits Exceeded has a higher priority than Fire Mode Active.
The log cannot be reset.
The following events are logged:
•
Fire mode activated.
•
Fire mode limits exceeded (warranty-aecting
alarms).
All other alarms occurring while re mode is active are
logged as usual.
NOTICE
During re mode operation, all stop commands to the
frequency converter are ignored, including coast, coast
inverse, and external interlock.
NOTICE
If setting the command [11] Start Reversing on a digital
input terminal in parameter 5-10 Terminal 18 Digital
Input, the frequency converter understands this
command as a reversing command.
24-00 FM Function
Option: Function:
NOTICE
In re mode, alarms are produced or
ignored in accordance with the selection
in parameter 24-09 FM Alarm Handling.

In this mode, the motor continues to operate in
a clockwise direction.
[2] Enabled-
Run
Reverse
In this mode, the motor continues to operate in
a counterclockwise direction.
[3] Enabled-
Coast
While this mode is selected, the output is
disabled, and the motor is allowed to coast to
stop. When parameter 24-01 Fire Mode Congu-
ration is set to [3] Closed Loop, this mode
cannot be selected.
24-00 FM Function
Option: Function:
[4] Enabled-
Run
Fwd/Rev
In this mode, the motor operates in a clockwise
direction. When receiving a reversing signal, the
motor operates in counterclockwise direction. If
parameter 24-01 Fire Mode Conguration is set
to [3] Closed Loop, the motor cannot operate in
counterclockwise direction.
24-01 Fire Mode Conguration
Select to use closed-loop or open-loop operations.
Option: Function:
[0] * Open Loop
[3] Process
Closed Loop
NOTICE
When set to [3] Closed Loop, the
commands Reversing and Start
Reversing do not reverse the direction
of the motor.
Motor speed is determined by a reference
from the built-in PI controller varying the
motor speed as of a closed-loop control
process (for example constant pressure or
ow). Congure the PI controller in
parameter group 20-8* PI Basic Setting and
parameter group 20-9* PI Controller.
24-05 FM Preset Reference

This parameter denes which input on the frequency converter
should be treated as the source of the feedback signal.
