Introduction
The MBC10641 Microstep Driver has an output current capability of 1.5 Amps minimum to 10.0 Amps maximum (Peak Rating). The MBC10641 driver operates with either a transformer, whose input can be wired from 90-265 VAC or a DC voltage of 30-85 Volts. The inputs are optically isolated with a minimum sourcing of 7.0 mA per input (+5VDC minimum to +24VDC maximum). The clock input is set to receive either positive or negative edge clocks with a maximum frequency of 400KHz. The MBC10641 driver offers direction control and motor current ON/OFF capabilities. The Reduce Current Enabled automati- cally reduces motor current to 70% of set value after the last step is made (1sec delay). The driver has built-in features to indicate power on (Green LED), Clocks being received (Yellow LED) and fault condi- tions (Red LED).
With the MBC10641, various step resolutions can be implemented by the onboard dip switch. These divisions range from 200 steps per revolution to 12,800 steps per revolution. The bipolar drive configura- tion handles 4, 6 and 8 lead motors. Protection devices have been added to this driver for Phase to Phase Short-Circuit, Motor Mis-Wire, Over-Temperatureand Over-Voltageconditions.
Pin Descriptions
The inputs on the MBC10641 are optically isolated with the anode (+) and cathode (-) both brought out to the user. With no current going through the opto-diode, the input is considered high. To enable the input a minimum of 7.0 mA needs to be sourced or sinked through the opto-diode. This is done simply by placing a voltage of +5 to +24 VDC across the two inputs of the opto-diode. If sourcing current into the inputs, then all three cathodes (-) should be tied together and grounded as shown in Figure 4. If sinking current, then all three anodes (+) should be tied together to the +voltage as shown in Figure 3. Provided on the MBC10641 is an external +5VDC out, which can be used to power the inputs for sinking mode only. However if you use this voltage, isolation is not preserved.
