141 Set Ratchet Negative
Mode
BYTE 1 Bit 0 = Ignore Negative Input - Negative direction
master encoder input will generate NO motor
movement
Bit 1 = Negate Negative Input - Master encoder
input in a negative direction will generate motor
movement in a positive direction.
Note: Selecting "Ignore Negative Input", above,
overrides this selection
Bit 2 = Buffer Negative Input - Negative direction
master encoder input is accumulated in a buffer
without generating motor movement.
Note: This selection will often be used together
with "Unbuffer Positive Input", below
Bit 3 = Unbuffer Negative Input - Negative
direction master encoder input will be used first
to reduce the accumulated positive directional
buffer then, only after this buffer is reduced to
zero, will generate motor movement in the
negative direction.
Note: This assumes "Buffer Negative Input",
above, is not selected.
