Value Function Description
20 Communication
setting
Whether terminal is active or inactive is determined by communication
address 0x2001.

23 Zero-speed running
2 (having output at
stop)
When output frequency is 0 during drive running, terminal set for this function
becomes on. When the drive stops, terminal remains on.
24 Accumulative
power-on time
reached
Terminal set for this function becomes on when accumulative power-on time
of the AC drive (F7-13) exceeds value set in F8-16.

30 Timing reached
On the condition that the timing function is enabled (F8-42 = 1), terminal
set for this function becomes on when current running time of the AC drive
reaches the set time.
31 AI1 input exceeding
limit
Terminal set for this function becomes on when AI1 input is larger than value
set in F8-46 (AI1 input voltage upper limit) or smaller than value set in F8-45
(AI1 input voltage lower limit).
32 Load lost
Terminal set for this function becomes on when load gets lost.
33 Reverse running
Terminal set for this function becomes on when the AC drive runs in reverse
direction.

35 IGBT temperature
reached
Terminal set for this function becomes on when heatsink temperature of
inverter IGBT (F7-07) reaches IGBT temperature threshold (F8-47).

37 Frequency lower
limit reached
(having output at
stop)
The terminal set for this function becomes on when the running frequency
reaches the frequency lower limit. When the drive stops, the terminal remains
on.
38 Alarm output
If a fault occurs on the AC drive and the AC drive continues to run, terminal
set for this function outputs an alarm signal.
39 Motor overheat
pending
Terminal set for this function becomes on when motor temperature reaches
value set in F9-58 (Motor overheat pending threshold). You can view motor
temperature by using U0-34.
40 Current running
time reached
Terminal set for this function becomes on when current running time of the
AC drive exceeds value set in F8-53.
41 Fault output
When a fault occurs on the AC drive (except undervoltage), terminal set for
this function becomes on.
