■ Main Circuit Teminal Functions
Terminals symbol Terminal function
Grounding terminal for connecting inverter. There are
3 terminals in total. 2 terminals in the terminal board, 1
terminal in the cooling fin.
200V class: single-phase 200~240V-50/60Hz *Single-phase input: R/L1
and S/L2 terminals
R/L1, S/L2, T/L3 3-phase 200~240V-50/60Hz
400V class: 3-phase 380~500V-50/60Hz
U/T1, V/T2, W/T3 Connect to a (three-phase induction) motor.
P(+), PR Connect to braking resistors. Change parameters f304, f305, f309
, if necessary.
N(-) This is a negative potential terminal in the internal DC main circuit. DC common power can be input across
the P(+) terminals (positive potential).
P1, P(+) Terminals for connecting a DC
reactor (DCL: optional external device). Shorted by a short bar when shipped
from the factory. Before installing DCL, remove the short bar.
■ Control Circuit Terminal Functions
Multifunction programmable
contact input
Shorting across FR-COM causes forward rotation; open
causes slowdown and stop.
Shorting across FR-COM causes reverce rotation; open
causes slowdown and stop.
Shorting across RST-COM causes a held reset when
the
inverter protector function is operating. Note that when
the inverter is operating normally, it will not operate even
if there is a short across RST-COM.
Shorting across DFL-COM causes preset speed operation.
Shorting across DFM-COM causes preset speed operation.
Shorting across DFH-COM causes preset speed opera
tion.

Power output for analog input setting.
+V
Multifunction programmable analog input. Standard default
setting: 0-10Vdc input and 0-60Hz frequency. The function can
be changed to 4-20 mAdc (0-20 mA) current input by flipping
the VRF slide switch to the I position.
Multifunction programmable analog input. Standard default
setting: 0-10Vdc input and 0-50Hz (50Hz setting) or 0-60Hz
(60Hz setting) frequency.
Multifunction programmable analog output.
Standard default setting: output freguency. Connect a 1mAdc
full-scale ammeter or 7.5Vdc (10Vdc)-1mA full-scale voltmeter.
The function can be changed to 0-20mAdc (4-20mA) current
output by flipping the FRQ slide switch to the I position.

When the source logic is used, a common terminal 24Vdc is
connected.
P24V
Multifunction programmable open collector output. Standard
default settings detect and output speed reach signal output
frequencies.
The OM terminal is an isoelectric output terminal. It is insulated
from the COM terminal.
These terminals can also be used as multifunction
programmable pulse train output terminals.

Note 1: By changing parameter setting, this terminal can also be used as a multifunction programmable contact input terminal.
When the inverter is used in a sink logic configuration, a resistor (4.7k at 0.5W) should be inserted between the P24 and VRF/VRF2 terminals.
Also, the slide switch for the VRF terminal needs to be turned to the V position.
Note 2: Multifunction output terminals to which two different functions can be assigned.
