Description
1
EXT5V
The driver outputs a 5V power supply for external
signals.Maximum load: 150mA.
It can be used for power supply of optical encoder.

IN6+/EA+
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.

IN6-/EA-
5
IN5+/EB+
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.
