Selecting Active Pulse Edge or Active Level and Control Signal Mode There are two jumpers J1 and J3 inside the PM752 specifically for selecting active pulse edge or effective level and control signal mode, as shown in figure 2. Default setting is PUL/DIR mode and rising edge active (NPN, and PNP control signal is on the contrary). -

Selecting Supply Voltage The power MOSFETS inside the PM752 can actually operate within +20 ~ +75VDC, including power input fluctuation and back EMF voltage generated by motor coils during motor shaft deceleration. Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps. -

The current automatically reduced to 60% of the selected dynamic current one second after the last 4000 pulse. Theoretically, this will reduce motor heating to 36% (due to P=I *R) of the original value.
