The driver parameters are configured via RS232 serial communication. The communication protocol is as follows:
| Parameter Address | Parameter Name | Range | Default | Remarks |
|---|---|---|---|---|
| *0 | Working Current | 0-99 | 40 | Motor Rated Current * 10 |
| *1 | Closed-loop Current Percentage | 0-100 | 80 | |
| *2 | Reserved | |||
| *3 | Voltage Monitoring | |||
| *4 | Edge Trigger | |||
| *5 | Internal Pulse Smoothing | |||
| *6-10 | Reserved | Refer to internal documentation for details | ||
| *11 | Arbitrary Subdivision Mode Setting | Effective for program customization only | ||
| *12 | Control Mode | |||
| 0: Single Pulse; | ||||
| 1: Dual Pulse; | 0-2 | |||
| 2: Internal Speed Mode | ||||
| *13 | Following Error Limit | 0-99 | 40 | Error pulses = Set value * 100 |
| *14 | Current Loop Kp | 0-99 | 40 | Spark Motor: STM5780C Recommended value: 40 |
| *15 | Position Loop Differential Gain Kd | 0-99 | 10 | For factory setting only. Do not modify. |
| *16 | Position Loop Feedforward Gain Kvff | 0-100 | 30 | For factory setting only. Do not modify. |
| *17 | Position Loop Proportional Gain Kp | 0-300 | 50 | For factory setting only. Do not modify. |
| *18 | Position Loop Integral Gain Ki | 0-300 | 15 | For factory setting only. Do not modify. |
Compatible Motors: All series of 42/57/60.
| Terminal Number | Symbol | Name | Description |

The input voltage must not exceed DC 50V.
The input pulse signal is active on the falling edge. Control via the rising edge requires setting internal driver parameters.
When the driver temperature exceeds 75°C, the driver stops working and the fault indicator (ALM) lights up. The driver requires a power cycle to resume operation only after the temperature drops to 50°C. If overheating protection is triggered, please install a heat sink.
If the overcurrent (load short circuit) fault indicator (ALM) lights up, please check the motor wiring and other potential short circuit faults. A power cycle is required to recover after the fault is resolved.
If the "No Motor" fault indicator (ALM) lights up, please check the motor wiring. A power cycle is required to recover after the fault is resolved.
For optimal matching and performance, please select Spark Stepper Motors.
The DIP switch DS is used to change the motor rotation direction. OFE is for CCW direction, and ON is for CW direction.
