The drive also includes an automatic feature to lower motor current by 50% anytime the motor is left at rest for more than one second. 0.25 0.25 0.15 3.00 The amplifier regulates motor current by chopping .875 at a constant, inaudible frequency. Phase current is selected from 32 levels by a DIP switch. Full or half resolution is DIP switch selected.
