It is better to separate them by at least 10 cm otherwise the disturbing signals generated by motor will easily disturb pulse direction signals causing motor position error system instability and other failures e Ifa power supply serves several drivers separately connecting the drivers is recommended instead of daisy chaining e Itis prohibited to pull and plug connector P2 while the driver is powered ON because there is high current flowing through motor coils even when motor is at standstill Pulling or plugging connector P2 with power on will cause extremely high back EMF voltage surge which may damage the driver 9 Typical Connection A complete stepping system should include stepping motor stepping driver power supply and controller pulse generator A typical connection is shown as figure 10 M335 Microstepping Driver Manual V1 0 ECG SA VE BA SE Controller MA860H PUL er vcce M PU v r lt B PA R 700 a R De k za u song ENA 7700 i al FMA v p c F MIB A z gt x Sparx Mona 5 5 f AC 18 80VAC 24 110VDC 0 f VCC SV Ro IKI PowervO 123W t VCC 2V ReZKi Powar gt 120W 8 VCC 24V R must be oorradod to contei nagnal krme Figure 9 1 Typical connection 10 Sequence Chart of Control Signals In order to avoid some fault operations and deviations PUL DIR and ENA should abide by some rules shown as follow

9. example using 4A supply for 3A motor driver operation On the other hand if unregulated supply is used one may use a power supply of lower current rating than that of motor typically 5096 7096 of motor current The reason is that the driver draws current from the power supply capacitor of the unregulated supply only during the ON duration of the PWM cycle but not during the OFF duration Therefore the average current withdrawn from power supply is considerably less than motor current For example two 3A motors can be well supplied by one power supply of 4A rating M335 Microstepping Driver Manual V1 0 ECG SA VE BA SE 6 2 Multiple Drivers It is recommended to have multiple drivers to share one power supply to reduce cost if the supply has enough capacity To avoid cross interference DO NOT daisy chain the power supply input pins of the drivers Instead please connect them to power supply separately 6 3 Selecting Supply Voltage The power MOSFETS inside the MA860H N can actually operate within 18 80VAC or 24 200VDC 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 However higher voltage may cause bigger motor vibration at lower speed and it may also cause over voltage protection or even driver damage Therefore it is suggested to choose only sufficien
