3.4.1.2 X3/EN, X4/AR Digital Inputs
The X3/EN, X4/AR are digital inputs operation 5-24V optically isolated single-ended signal, sinking
or souring, 5-24VDC, minimum pulse width 50
μ
s, maximum pulse frequency 10KHz
X3 can be con
fi
gured as enable signal input to servo on or off the motor and X4 can be con
fi
gured
as alarm reset signal input to clear the alarm and turns to the normal status as servo off.
In the velocity mode, X4 can also be con
fi
gured as speed switch signal to change the speed to
another one.
X3 and X4 can be con
fi
gured as general purpose input for WI, OI, FS or SH and other commands.
Because the input is an optically isolated circuit, a 5-24V power supply is needed. For example,
you can use the power supply of the PLC when you are using a PLC control system, but if you
want to connect a relay or mechanical switch to the input, you must need a power supply.
XCOM is an electronics term for a single-ended signal connection to a common voltage. In the
case of RS series, if you are using a sourcing(PNP) input signals, you need to connect XCOM
to the ground(power supply -),if you are using a sinking(NPN) input signals ,the XCOM need to
connect to the power .
NOTE:
If current is flowing into or out of an input, the logic state of that input is low or closed.
If no current is flowing ,or the input is not connected, the logic state is high or open.
The chats below show how to connect to EN and AR. Please select the polarity of the inputs by
using the Step-Servo Quick Tuner.
