(2) Run/stop command terminal (FWD, REV)
FWD terminal is short-circuit to CM terminal in the factory. Pressing the RUN key on the keypad
panel can start forward operation. If function F02 is 0, short-circuit FWD and CM and press the
RUN key for forward operation, or short-circuit REV and CM for reverse operation. If function F02
is 1, then short-circuit FWD and CM for forward operation, or REV and CM for reverse operation.
Regardless of whether function F02 is set to 0 or 1, short-circuiting both FWD

brings the drive to a deceleration-stop. Refer to F02 “Operation method” for details.
(3) Analog input terminal (13, 12, 11, C1)
Use these terminals to connect external input analog voltage and analog current and frequency
setting device (POT). For connecting a contact to this circuit, use a twin contact for fine current
signal. Do not use a contact for terminal 11.
!
WARNING
1. The STOP key is valid only when the function has been set. Use another
switch for emergency stop. When the data of F02 is selected as “2” or “4”,
operation cannot be stopped using the STOP key on the keypad panel.
Risk of accident!
*Note the following when wiring:
(1) Surge absorber connection
When the exciting coil of the magnetic contactor or relay in the
control circuit or drive peripheral circuit is opened or closed, a
surge voltage (noise) is generated with a sudden current
change. Due to this surge voltage, the drive control circuit or
peripheral equipment may malfunction. If so, directly connect
a surge absorber to both ends of the coil. (See Figure 2-3-4).)
(2) Control circuit wiring
¬
Wires connected to control circuit terminals must be AWG
20 (0.5mm
2
) shielded wire or twisted vinyl wire. Remove
the sheath as shown in Figure 2-3-5 and then connect it.
-
Keep the wiring of the main circuit, external relay sequence
circuit and control circuit as far away from each other as
possible. If they must be adjacent, cross them at
right angles.
®
Use a twisted-pair shielded wire for long wiring
distances.
(3) Ground connection
Connect one end of the shield of a shielded or
twisted-pair shielded wire to the ground terminal as
shown in Figure 2-3-6. Do not connect the other end.
