4. Heat Dissipation Precautions
The reliable operating ambient temperature for closed-loop integrated motors is typically within -5℃ ~ 45℃. Normal operating temperature is 50-80℃. If exceeding 80℃, it is necessary to evaluate whether the operating conditions and integrated motor selection are appropriate. If necessary, install a fan near the driver for forced cooling to ensure the driver operates within the reliable working temperature range.
5. LED Status Indicator
The red LED serves as both power indicator and fault display. When the driver is powered on, the LED is constantly on; when the driver is powered off, the LED is off. When a fault occurs, the indicator flashes in a 5-second cycle; when the fault is cleared by the user, the LED remains constantly on. The number of flashes within 5 seconds represents different fault information, as shown in the following table:
| No. | Flash Count | Fault Description |
|---|---|---|
| 1 | 1 | Overcurrent or inter-phase short circuit fault |
| 2 | 2 | Overvoltage fault |
| 3 | 3 | Undervoltage alarm |
| 4 | 7 | Position deviation alarm (excessive error) |
| 5 | 9 | Driver error, requires maintenance |
| 6 | 4 | Network congestion fault, requires power cycle (flashes 4 times, does not cycle) |
When a fault occurs, the driver will stop and display the corresponding fault code (item 3 network congestion has no code). The user must re-enable the driver or power cycle to clear the fault. When the driver detects a fault, it saves the latest fault to the EEPROM in a queue format. The driver can save up to 10 latest historical faults.
6. OUT Output Port Wiring Diagram
OUT /OUT- ports are differential output ports, allowing maximum voltage of 24V. Port instantaneous output current is 100mA, continuous output current is 50mA. To protect the port, when connecting external brakes, solenoid valves, relays, etc., freewheeling diodes must be connected across the devices to prevent port damage.

7. Zero-return Function
Zero-return function with two trajectory A and when limit signal is triggered and not:

8. Communication Protocol
Communication uses standard MODBUS protocol, supporting 0x03 (read register), 0x06 (write single register), 0x10 (16) (write multiple registers). Serial communication format: baud rate 9600~115200, 8 data bits, no parity, 1 stop bit.

Note: Pulse signals, directional signals, and enable signals can receive up to 5V signals,
If the control signal is 12V, a 1K resistor needs to be connected.
If the control signal is 24V, it is necessary to connect 2.2K resistors.
In addition to Differential wiring, AP42 Driver also supports common anode connection and common cathode connection:


Dip Switch Settings:

SW1 SW2 SW3 set Current,
SW4 SW5 SW6 Set Micro-Step,
SW8 Set direction CW/CCW.
SW9 SW10, Choose Working Mode
1. Set working current by SW1, SW2, SW3:

The default peak current at the factory is 0.5A, can be set through the serial port before sale,
The adjustable current range is any value between 0.1A and 2.2A (peak).
Set Stepper Motor's default rotation direction
SW8=on, CW
SW8=off, CCW

Note: the default rotation direction according to the wiring,
Swap wiring phase A A-(or B B-) will change the rotation direction.
Set Working Mode by SW9, SW10:
| SW9 | SW10 | Working Mode |
| on | on | Spontaneous pulses |
| on | off | self-test |
| off | on | double pulse |
| off | off | Pulse & Direction |
Set Micro-Step and working speed by SW4,SW5,SW6 SW7:

Note: set SW9,SW10 for Spontaneous pulses mode, working speed will be effective when connect the 5V pulse signal.

Set ID address, Baud Rate and Ouptut current by SW1~SW10:
Set ID address:

Note: The formula for calculating the ID table is: ID=1*SW1 2*SW2 4*SW3 8*SW4 16*SW5.
The default ID is 0, 0 means broadcast address for global control
Set Baud Rate:

Note: When the communication baud rate in the table cannot meet the usage requirements, the baud rate can be
customized by the host computer when SW6 and SW7 are turned ON.
