BH-2H860
The BH-2H860 is full digital 2 phase stepper driver based on DSP control. The drive voltage of which is from 18V to 80VAC(24V to 110VDC). It is designed for use with the 2 phase hybrid stepper motor of all kinds with 57mm to 86mm outside diameter, regulated phase current from 2.0A to 6.0A. The highest micro step is 51200ppr. It is widely used in small size numerical control devices such as curving machine, packing machine, CNC and etc.
FEATURES
l 16 channels constant angle, constant torque micro steps, highest micro step: 51200ppr
l Highest response frequency: 200Kpps
l Current of winding will be reduced by approximately 50% when no step pulse command is received for 1.5 second
l Opto-isolated signal I/O
l Drive current is adjustable in 8channels from 2.0A/phase to 6.0A/phase
l Single power supply from 18V to 80VAC(24V to 110VDC)
CURRENT SETTING
Stepper driver working current is set by DIP switches SW1 to SW3. SW4 is used to set the current mode.
| Working current (A) | 2.0 | 2.5 | 3.2 | 3.8 | 4.2 | 4.8 | 5.3 | 6.0 |
| SW1 | ON | OFF | ON | OFF | ON | OFF | ON | OFF |
| SW2 | ON | ON | OFF | OFF | ON | ON | OFF | OFF |
| SW3 | ON | ON | ON | ON | OFF | OFF | OFF | OFF |
| SW4 | OFF, half current | |||||||
| ON, full current | ||||||||
SUBDIVISION (MICRO STEP) SETTING
The subdivision (micro step) is set by DIP switches SW5 to SW8, 16 channels in total. SW9 and SW10 are used to set the driver function.
| Subdivision (micro step) ppr | 2.0 | 2.5 | 3.2 | 3.8 | 4.2 | 4.8 | 5.3 | 6.0 |
| SW5 | 2.0 | 2.5 | 3.2 | 3.8 | 4.2 | 4.8 | 5.3 | 6.0 |

| SW9 | ON, double pulse: PU is positive pulse signal, DR is negative pulse signal | |||||||
| OFF, single pulse: PU is pulse signal, DR is direction signal | ||||||||
| SW10 | Self detect switch (OFF: accept external pulse, ON: the driver send pulse to make the motor work at the speed of 30r/m) | |||||||
CAUTION
1. Supply voltage shouldn’t exceed 80VAC(110VDC).
2. Input control signal is +5V-+28V, current-limiting resistance should be connected when it is over +5V.
3. Input pulse signal is effective with the falling edge.
4. Alarm indicator ALM lights and the driver stops working when the driver temperature is over 80℃. It restarts working until the temperature falls to 50℃. The heat sink is needed when overheat occurs.
5. Alarm indicator ALM lights when overcurrent (short of load) occurs. Please check motor’s connection and other shorts and turn the power supply on after removing the trouble.
6. Alarm indicator ALM lights when no motor connected or poor connection. Please check motor’s connection and turn the power supply on after removing the trouble.
