2.4. Digital input and output interface
The EP series driver has 6 digital input ports and 2 digital output ports. The digital
input and output ports can be freely configured with various functions according to their
own application requirements.
2.4.1. Pin definition
Table 2-1 Pin definition of CN
The driver outputs a 5V power supply for external
signals.Maximum load: 150mA.
It can be used for power supply of optical encoder.
Differential input signal interface, 5V~24V compatible.
In open-loop external pulse mode, it can receive direction.
In closed-loop mode, this port is used to receive quadrature
encoder A-phase signal.
Note:The closed-loop mode is only applicable to the EPT60.
Differential input signal interface, 5V~24V compatible.
In open-loop external pulse mode, it can receive direction.
In closed-loop mode, this port is used to receive quadrature
encoder B-phase signal.
Note:The closed-loop mode is only applicable to the EPT60.
Universal input port 3, default to receive 24V/0V level signal.
Universal input port 4, default to receive 24V/0V level signal.
Universal input port 1, default to receive 24V/0V level signal.
Universal input port 2, default to receive 24V/0V level signal.
