5. Power supply specifications
5.1 Input power supply
+5V ± 5%, peak current 3A (Max. 2 sec., at spindle motor ON/OFF)
Note: Power supply current is usually 1.4A. But at a spin-up time the current increase to 3.0A. If the
power supply cable that is long and thin, power supply voltage is drop and out of the
operational condition of this drive. Please use a short and thick power supply cable.
Note: The voltage drop with the power supply cable is approximately as follows.
Wire Resistance (Ω/km) Voltage drop (V)* at 1m wire length and 3A current
AWG22 (Twist wire) 57.4 0.344
AWG18 (Twist wire) 23.7 0.142
AWG22 (Single wire) 56.3 0.338
AWG18 (Single wire) 22.2 0.133
* The drop voltage in the both of the ground line and the power supply line
* This value changes according to the electric wire maker and the use temperature.
5.2 Power consumption
Average Less than 6.7W
Stand-by period: Less than 6.0W
Seek period: Less than 11.0W
Sleep period: Less than 1.0W
5.3 Allowable ripple voltage
Less than 100 mVp-p (includes spike noise)
