Value )unction Description
19
Undervoltage state
output
If the A
C drive is in undervoltage state, the terminal
becomes ON.
20
Communication
setting
Refer to the communication protocol.
21 Reserved Reserved.
22 Reserved Reserved.
23
=ero-speed running 2
(having output at stop)
If the output frequency of the A
C drive is 0, the terminal
becomes ON. In the state of stop, the signal is still ON.
24
Accumulative power-
on time reached
If the A
C drive accumulative power-on time ()7-13)
exceeds the value set in )8-16, the terminal becomes ON.
25
)requency level
detection )DT2 output
Refer to the descriptions of )8-28 and )8-29.
26 )requency 1 reached Refer to the descriptions of )8-30 and )8-31.
27 )requency 2 reached Refer to the descriptions of )8-32 and )8-33.
28 Current 1 reached Refer to the descriptions of )8-38 and )8-39.
29 Current 2 reached Refer to the descriptions of )8-40 and )8-41.
30 Ti
ming reached
If the timing function ()8-42) is valid, the terminal becomes
ON after the current running time of the AC drive reaches
the set time.
31
AI1 input limit
exceeded
If A
I1 input is larger than the value of )8-46 (AI1 input
voltage upper limit) or lower than the value of )8-45 (AI1
input voltage lower limit), the terminal becomes ON.
32 Load becoming 0 If the load becomes 0, the terminal becomes ON.
33 Reverse running
If the A
C drive is in the reverse running state, the terminal
becomes ON.
34 =ero current state Refer to the descriptions of )8-28 and )8-29.
35
Module temperature
reached
If the heatsink temperature of the inverter module (
)7-07)
reaches the set module temperature threshold ()8-47), the
terminal becomes ON.
36
Software current limit
exceeded
Refer to the descriptions of )8-36 and )8-37.
37
)requency lower
limit reached (having
output at stop)
If the running frequency reaches the lower limit, the terminal
becomes ON. In the stop state, the signal is still ON.
38 Alarm output
If a fault occurs on the A
C drive and the AC drive continues
to run, the terminal outputs the alarm signal.
39
Motor overheat
warning
If the motor temperature reaches the temperature set in
)9-58 (Motor overheat warning threshold), the terminal
becomes ON. You can view the motor temperature by using
U0-34.
40
Current running time
reached
If the current running time of A
C drive exceeds the value of
)8-53, the terminal becomes ON.
