ABB HESG324442R111 Pulse input module

Maximum motor speed performance will be achieved by using as high a motor supply voltage as possible without ever exceeding 75 volts. Of course lower voltages can also be used (so long as the voltage is greater than the minimum specified value of 24 volts) but motor torque will drop more rapidly as speed increases. The peak bus voltage (excluding any spiking due to current switching in the drive module or any regeneration effects) is approximately equal to: (1.414 * Actual Secondary rms voltage) - 1.5

This assumes a 0.75 volt drop across each rectifier diode. 

To insure this, as well as to discharge the bus capacitor when AC power is removed, it is recommended that a bleed resistor be placed across each bus capacitor as shown.If, for example, the secondary rms voltage is 40 Vac, the peak bus voltage will be 1.414 * 40 - 1.5 = 55 volts. A transformer with 115 Vac primary and 40 Vac secondary would produce 55 volts peak bus voltage under nominal line conditions and at rated loading.
