LC
FUNCTION:
Low Current Stepper Mode
DESCRIPTION:
Causes the amp enable line for the specified axes to toggle (disabling the stepper drives)
when the respective axes stop (profiler holding position). Each axis is handled
individually with either full, 25%, or no current at rest. This will reduce current
consumption, but there will be low or no holding torque at rest. The MT command
must be issued prior to the LC command.
ARGUMENTS:
LC n,n,n,n,n,n,n,n where
n = 0 Normal (stepper drive always on)
n = 1 Low current stepper mode (25% holding current)
n = 2 No current stepper mode (0% holding current) (AMP 206x0 only)
n = ? Returns whether the axis is in low current stepper mode
