Settings
Functions Descriptions
0 No Function Output terminal with no function
1 Indication during RUN Activates when the drive is not in STOP.
2
Operation speed
reached
Activates when output frequency of the drive reaches the
setting frequency.
3
Desired frequency
reached 1 (Pr.02-22)
Activates when the desired frequency (Pr.02-22) is reached.
4
Desired frequency
reached 2 (Pr.02-24)
Activates when the desired frequency (Pr.02-24) is reached.
5
Zero speed (Frequency
command)
Activates when frequency command = 0 (the drive must be
in RUN status).
6
Zero speed, includes
STOP
(Frequency command)
Activates when frequency command = 0 or stopped.
7 Over-torque 1
Activates when the drive detects over-torque. Pr.06-07 sets
the over-torque detection level (motor 1), and Pr.06-08 sets
the over-torque detection time (motor 1).
Refer to Pr.06-06–06-08.
8 Over-torque 2
Activates when the drive detects over-torque. Pr.06-10 sets
the over-torque detection level (motor 2), and Pr.06-11 sets
the over-torque detection time (motor 2).
Refer to Pr.06-09–06-11.
9 Drive is ready Activates when the drive is ON with no error detected.
10 Low voltage warn (Lv)
Activates when the DC bus voltage is too low
(refer to Pr.06-00 Low Voltage Level).
11 Malfunction indication Activates when fault occurs (except Lv stop).
13 Over-heat warning
Activates when IGBT or heat sink overheats; to prevent the
drive from shutting down due to over-heating (refer to Pr.06-
15).
14
Software brake signal
indication
Activates when the soft brake function is ON (refer to Pr.07-
00).
15 PID feedback error Activates when the PID feedback signal error is detected.
16 Slip error (oSL) Activates when the slip error is detected.
17
Count value reached
(Pr.02-20)
When the drive executes external counter, this contact
activates if the count value is equal to the setting value for
Pr.02-20.
This contact deactivates when the setting value for Pr.02-20
> Pr.02-19.
18
Count value reached
(Pr.02-19)
When the drive executes the external counter, this contact
activates if the count value is equal to the setting value for
Pr.02-19.
