6At 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.

7Minimum current loading for each supply voltage is not less than 4% of the maximum operating current shown.

8Use separate ground returns for +5V and +12V supplies.

9Where 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.

10No terminator power. See 11.7.3.4 in the Cheetah 9 Product Manual.
