Details

BH-2H445

The BH-2H445 is full digital 2 phase stepper driver based on DSP control. The drive voltage of which is from 20V to 50VDC. It is designed for use with the 2 phase hybrid stepper motor of all kinds with 42mm to 57mm outside diameter, regulated phase current from 1.0A to 4.0A. The highest micro step is 40000ppr. 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: 40000ppr

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 1.0A/phase to 4.0A/phase

l          Single power supply from 24V to 50VDC  

CURRENT SETTING

Stepper driver working current is set by DIP switches SW1 to SW3. SW4 is used to set the current mode.

CAUTION

1.       Supply voltage shouldn’t exceed 50VDC.

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.
