Symbol Name Functions
[Y5A/C] General
purpose
relay output (1) A general-purpose relay contact output usable as well as the function of the
transistor output terminal [Y1], [Y2] or [Y3].
Contact rating: 250 VAC 0.3 A, cos
φ
= 0.3, 48 VDC, 0.5 A
(2) Switching of the normal/negative logic output is applicable to the following two
contact output modes: "Active ON" (Terminals [Y5A] and [Y5C] are closed
(excited) if the signal is active.) and "Active OFF" (Terminals [Y5A] and [Y5C] are
opened (non-excited) if the signal is active while they are normally closed.).

[30A/B/C] Alarm relay
output
(for any
error)
(1) Outputs a contact signal (SPDT) when a protective function has been activated to
stop the motor.
Contact rating: 250 VAC, 0.3A, cos
φ
= 0.3, 48 VDC, 0.5A
(2) Any one of output signals assigned to terminals [Y1] to [Y3] can also be assigned
to this relay contact to use it for signal output.
(3) Switching of the normal/negative logic output is applicable to the following two
contact output modes: "Terminals [30A] and [30C] are closed (excited) for ON
signal output (Active ON)" or "Terminals [30B] and [30C] are closed (non-excited)
for ON signal output (Active OFF)."
Communi
cation
RJ-45
connector
for the
keypad Standard
RJ-45
connector (1) Used to connect the inverter with PC or PLC using RS-485 port. The inverter
supplies the power to the keypad through the pins specified below. The extension
cable for remote operation also uses wires connected to these pins for supplying
the keypad power.
(2) Remove the keypad from the standard RJ-45 connector, and connect the RS-485
communications cable to control the inverter through the PC or PLC
(Programmable Logic Controller). Refer to Section 2.3.8 "Setting up slide
switches and handling control circuit terminal symbol plate" for setting of the
terminating resistor.
Figure 2.27 RJ-45 Connector and its Pin Assignment*
* Pins 1, 2, 7, and 8 are exclusively assigned to power lines for the keypad, so
do not use those pins for any other equipment.
