Terminals

Wiring is carried out at the connection terminals. The assignments are as follows:

No.	Name	Input/output	Function
1	PA1	Output	Motor winding A – connection 1
2	PA2	Output	Motor winding A – connection 2
3	48 V	Input	Motor voltage supply DC 20.4 V – 57.6 V
4	ENC5V	Output	Encoder voltage supply 5 V
5	ENC+A	Input	Encoder input +A (5 V/TTL)
6	ENC+B	Input	Encoder input +B (5 V/TTL)
7	ENC+Z	Input	Encoder input +Z (5 V/TTL)
8	DI1	Input	Digital input 1
9	DO	Output	Digital output
10	PB1	Output	Motor winding B – connection 1
11	PB2	Output	Motor winding B – connection 2
12	M0V	Input	Motor voltage supply GND
13	ENCoV	Output	Encoder voltage supply GND
14	ENC-A	Input	Encoder input -A (5 V/TTL)
15	ENC-B	Input	Encoder input -B (5 V/TTL)
16	ENC-Z	Input	Encoder input -Z (5 V/TTL)
17	DI2	Input	Digital input 2
18	DI3	Input	Digital input 3
18	DI3	Input	Digital input 3

INFORMATION

Please note the following when connecting the motor winding:

If you connect a motor branch to different output drivers, such as PA1 and PB1, this can destroy the output drivers of the stepper motor module.
Overtemperature of the output stage will cause the device to shut down.
Only connect the windings of a motor branch to the terminals of the same output driver of the stepper motor module, e.g. one motor branch to PA1 and PA2, the other motor branch to PB1 and PB2.

Fusing

The DC 20.4 V – DC 57.6 V voltage supply for the stepper motor must be protected with an external fuse appropriate to the maximum current, i.e. maximum 8 A with an 8 A fuse (fast-acting) and/or an 8 A miniature circuit breaker with "Z" characteristics.
