◆ CONNECTION OF MOTOR CORD PLUG
Confirming the position of Motor Cord Plug, insert the
plug into Motor Output Connector located on the front
side of control unit and tighten with the union nut.
( Fig. 4 )
◆ CONNECTION OF POWER SOURCE CORD
Insert AC power source cord firmly into Inlet Box
assembled with power source fuse located on the rear
panel of Control Unit ( Fig. 5 )
◆ CONNECTION OF SEQUENCE
CONTROL TERMINAL
Confirming the position of Sequence Control Plug,
insert it firmly into the Sequence Control Connector
located on the rear panel of Control Unit. ( Fig. 5 )
※ In case of making speed control without using sequence control, turn Manual / Auto Select
Switch to MANUAL. Starting and stopping the motor can be operated with Forward / Reverse
Select Switch so that the connection of Sequence Control Cord is not necessary.
¡Motor runs when ON / OFF terminals ( No. 3, 4 ) are made short circuit and motor stops when the
terminals are OFF.
¡When Reset Switch works during the rotation, the transistor connected to TRIP terminals ( No. 1,
2 ) are ON and can be used for the control of other machinary.
( The max. standard of transistor is Vc
max. standard value )
Electronic Circuit in Control Unit
¡Wiring of Sequence Control Cord is as follows :
