Frequency setting
power supply
5VDC, permissible load current
10mA
When the frequency setting potentiometer is
connected in the factory-set state, connect it to
terminal 10.
When it is connected to terminal 10E, change the
input specifications of terminal 2.

Frequency setting
(voltage)
By entering 0 to 5VDC (0 to 10VDC), the maximum output frequency is reached at
5V (or 10V) and I/O are proportional. Switch between input 0 to 5VDC (factory
setting) and 0 to 10VDC from operation terminal. Input resistance 10k
Ω
. Maximum
permissible voltage 20V.
4
Frequency setting
(current)
By entering 4 to 20mADC, the maximum output frequency is reached at 20mA and
I/O are proportional. This input signal is valid only when the AU signal is on. Input
resistance 250
Ω
. Maximum permissible current 30mA.

10VDC, this signal is added to the frequency setting
signal of terminal 2 or 4. Switch between input 0 to

10VDC
(factory setting) from operation terminal. Input resistance 10k

. Maximum
permissible voltage
±
20V.
Input signals

Frequency setting
input common
Common to the frequency setting signal (terminal 2, 1 or 4) and analog output
terminal AM. Do not earth.
Contact
A B C
Alarm output
Change-over contact output indicating that the output has been
stopped by the inverter protective function activated.
200VAC 0.3A, 30VDC 0.3A. Alarm: discontinuity across B-C
(continuity across A-C), normal: continuity across B-C
(discontinuity across A-C).
RUN
Inverter running
Switched low when the inverter output frequency is equal to or
higher than the starting frequency (factory set to 0.5Hz,
variable).
Switched high during stop or DC dynamic brake operation
(note1)
Permissible load 24VDC 0.1A.
SU
Up to frequency
Switched low when the output frequency has reached within
±
10% of the set frequency (factory setting, variable). Switched
high during acceleration, deceleration or stop
(note 1)
. Permissible
load 24VDC 0.1A.
OL
Overload alarm
Switched low when the stall prevention function has caused
stall prevention to be activated. Switched high when stall
prevention is reset
(note 1)
. Permissible load 24VDC 0.1A.
IPF
Instantaneous power
failure
Switched low when instantaneous power failure or
undervoltage protection is activated
(note 1)
. Permissible load
24VDC 0.1A.
FU
Frequency detection
Switched low when the output frequency has reached or
exceeded the detection frequency set as appropriate. Switched
high when below the detection frequency
(note 1)
. Permissible load
24VDC 0.1A

Note1: Low indicates that the open collector outputting transistor is on (conducts). High indicates that the
transistor is off (does not conduct).
Note2: Not output while the inverter is reset.
