142 Set Ratchet Positive
Mode
BYTE 1 Bit 0 = Ignore Positive Input - Positive direction
master encoder input will generate NO motor
movement.
Bit 1 = Negate Positive Input - Master encoder
input in a positive direction will generate motor
movement in a negative direction.
Note: Selecting "Ignore Positive Input", above,
overrides this selection.
Bit 2 = Buffer Positive Input - Positive direction
master encoder input is accumulated in a buffer
without generating motor movement.
Note: This selection will often be used together
with "Unbuffer Negative Input", above.
Bit 3 = Unbuffer Positive Input - Positive direction
master encoder input will be used first to reduce
the accumulated negative directional buffer then,
only after this buffer is reduced to zero, will
generate motor movement in the positive
direction.
Note: This assumes "Buffer Positive Input",
above, is not selected
Default = 0.
143 Get Motor Encoder
Output
DINT 4 cnts The motor encoder's output.
144 Get Master Encoder
Output
DINT 4 cnts The master encoder's output.
145 Get Ratchet State USINT 1 Provides the state of the ratchet.
0 = Disable
1 = Enable
146 Get Ratchet Buffer DINT 4 cnts The accumulated value stored in the buffer when
negative or positive input is set to buffer and/or
unbuffer. This value is automatically re-set to zero
at drive power up.
147 Get Ratchet Output DINT 4 cnts The position generated by the ratchet. This value
is automatically re-set to zero at drive power up.
148 Get Ratchet Position DINT 4 cnts The position generated by the ratchet. This value
is automatically reset to zero at power up.
149 Get Ratchet Velocity REAL 4 cnts/ sec The velocity command generated by the ratchet.
150 Get Input 1 State USINT 1 The current state, or condition, of the digital
input.
0 = Off
1 = On
