Encoder rotating in forward direction – “FRUN” (Function code data = 52),
Encoder rotating in reverse direction – “RRUN” (Function code data = 53)
This output signals come ON by encoder's rotation direction and speed regardless of running status
of the inverter.
In following figure, a speed diagram is shown with activation/deactivation of these signals. As soon
as speed reaches L108 (Encoder Rotation (Detection speed))
FRUN
or
RRUN
are activated
depending on the rotation detection.

Run command activated – AX2
(Function code data = 55)
This output signal comes ON by satisfying all of the following conditions.
- Run command ON
-
LU
is OFF
- No alarm ( ALM is OFF)
This output signal comes OFF by satisfying either of the following conditions.
- Run command OFF
- LU is ON
- Alarm (
ALM
is ON)
■
Motor overheat detected (PTC) – THM
(Function code data = 56)
This output signal indicates that a temperature alarm condition has been detected by a PTC (Positive
Temperature Coefficient) thermistor on the motor.
With this output signal assigned, setting function code H26 (PTC or NTC Thermistor) to "2" enables
the inverter to continue running instead of stopping with the alarm OH4 even if a temperature alarm
condition has been detected.

For details of the PTC thermistor, refer to the descriptions of function codes H26 and H27
(PTC Thermistor, Mode and Level).
■
Brake control – BRKS
(Function code data = 57)
This signal outputs a brake control command.
 For details, refer to the descriptions of function codes L80 to L84 (Brake Control) and H96.
