Note 1. Incorrect signal wiring can cause damage to Units and the Servo Driver.
Note 2. Leave unused signal lines open and do not wire them.
Note 3. ERB44-02 diodes (by Fuji Electric) or equivalent are recommended for surge absorption.
Note 4. When using a 3G2A5-NC111-EV1 Position Control Unit, origin search is carried out according
to the origin and origin proximity inputs. Set the origin and origin proximity for the mechanical
system. Even after the 3G2A5-NC111-EV1 completes the origin search and pulses are
stopped, pulses are still accumulated in the deviation counter in the Servo Driver. The Servo-
motor will move for the amount of residual pulses and then stop, so there may be a discrepan-
cy with the origin. In order to minimize the amount of the discrepancy, set the origin search
proximity speed as low as possible.
Note 5. Use the RUN signal to set whether the Servo can be turned ON/OFF.
Note 6. Class-3 grounds must be to 100
Ω
or less.
