Instructions of digital output terminal
Instructions of Y1 and Y2/DO output terminals
a) Internal power supply b) External power supply
Fig. 3-20 Wiring when Y1 and Y2/DO output with pull-up resistor
ATTENTION:
When set to be pulse output, Y2/DO terminal shall output 0~50kHz pulse signal.

Fig. 3-21 Wiring when Y1 and Y2/DO drive relay
ATTENTION:
When relay coil voltage is lower than 24V, a resistor as voltage divider should be mounted
between relay and output terminal, based on coil impedance.
Wiring instruction of relay output terminal
Control board of GK600 series drive is provided with a group of programmable relay dry
contact outputs. RA/RB/RC are relay contacts. RA and RB are normally closed, while RA
and RC are normally open. See parameter C1-02 for details.
ATTENTION:
In case inductive load (e.g. electromagnetic relay or contactor) is to be driven, a surge
voltage absorbing circuit such as RC absorbing circuit (note that its leakage current shall be
less than holding current of controlled contactor or relay), piezoresistor or fly-wheel diode
etc. shall be mounted (be sure to pay close attention to polarity in case of DC
electromagnetic circuit). Absorbing devices should be mounted close to the ends of relay or
contactor.
