AX500 Motor Controller Overview
22 AX500 Motor Controller User’s Manual Version 1.9b. June 1, 2007
ate from 12 to 24VDC and can sustain up to 15A of controlled current, delivering up to
360W (approximately 0.5 HP) of useful power to each motor.
The many programmable options of the AX500 are easily configured using the supplied PC
utility. Once programmed, the configuration data are stored in the controller's non-volatile
