- Page 5 4. POWER SUPPLY SECTION It is important to choose the appropriate power supply to make the driver operate properly Maximum Voltage Input: The internal power supply can operate from 24Vdc to 110Vdc, including power input fluctuation and back EMF voltage generated by motor coils during motor shaft deceleration, or from 18Vac to 80Vac via a transformer.
- Page 6 5. DRIVER VOLTAGE AND CURRENT SELECTION Selecting Supply Voltage: Higher supply voltage can increase motor torque at higher speeds. However, higher voltage may cause more motor vibration at lower speeds. It may also cause over-voltage protection and even damage the drive. Therefore, it is suggested to choose only sufficiently high supply voltage for intended applications.
