Motor Current
Switch selectable from 1.0 to 6.3A
steps.
Idle Current Reduction
Switch selectable to Not reduced, To 69%, To 50%,
or To 0%. Motor current is reduced to selected
level if a step pulse is not received for one second
for the To 50%, and To 0% settings. For the To
69%, setting, current is reduced after 10 millisec-
onds. Current is restored to full value on next
pulse.
