INSTALLATION AND WIRING

(2) Setting the number of encoder pulses and encoder rotation direction

Set the following parameters according to the encoder specification.

z The rotation direction of the encoder is displayed on the operation status indication (FWD,REV) of the control

panel.

z When using a conventional motor and an encoder cable (FR-VCBL/FR-JCBL), refer to the

Instruction Manual (detailed).

z Encoder output circuit

jumper connector

The jumper connector is fitted to

complimentary when shipped from

the factory. Switch its position

according to output circuit.
