1.3 Power Requirements 1.3 Power Requirements (1) Input Voltage • +5V ±5% • It is unnecessary for this drive to supply +3.3 V and +12 V power supplies. (2) Ripple Maximum Frequency +5 V 100 mV (peak to peak) DC to 1 MHz (3) Slope of an input voltage at rise The following figure shows the restriction of the slope which is +5 V input voltage at rise. The permissible range of +5 V slope is from 1V/20 μsec to 1V/20 msec, under the voltage range is between 2.0V and 4.5V. Figure 1.1 Permissible range of +5V rise slope C141-E293 1-7
