3.2.2 ENA
（
IN3
）port：
The default ENA port is the drive offline (enabled) function:
When the internal photocoupler is turned off, the driver outputs current to the motor;
When the internal photocoupler is turned on, the driver will cut off the current of each
phase of the motor to make the motor in a free state. At this time, the step pulse is not
responded.
When the motor is in an error state, the enable is automatically disconnected.
The level logic of the enable signal can be set to the opposite.
At the same time, this port can be multiplexed with other functions like IN1 and IN2.

（
OUT1
）port：
The driver includes an optically isolated output port ALM. By default, the ALM port is an alarm
output. When the driver is in an error state and a normal working state, the ALM outputs
different optocoupler levels.
