At power-up, the motor current regulator limits the +12V cur-
rent to an average value of less than value shown in table,
although instantaneous peaks may exceed this value. These
peaks should measure 5 msec duration or less.

Use separate ground returns for +5V and +12V supplies.

Where power is provided to multiple drives from a common
supply, carefully consider individual-drive power requirements.
Where multiple units are powered on simultaneously, be sure
the peak starting current is available to each device.
