Chapter 4 Configuring the Ultra5000 Drive
The following status is displayed by default for an Encoders branch of an online
drive.
Negate Positive Input
Master encoder input in a positive direction generates motor
movement in a negative direction.
Note: Selecting
, above, overrides this
selection.
Buffer Positive Input
Positive direction master encoder input is accumulated in a
buffer without generating motor movement.
Note: This selection is often used together with
, above.
Unbuffer Positive Input
Positive direction master encoder input is used first to reduce
the accumulated negative directional buffer then, only after this
buffer is reduced to zero, generates motor movement in the
positive direction.
Note: This assumes
, above, is not selected.

Description
Motor Encoder
Output
The motor encoder's output, in counts
Fault State
The current state of fault checking for the motor encoder

The motor encoder's Channel A
B
The motor encoder's Channel B
S1
The motor encoder's Hall Input 1

Master Encoder
Output
The master encoder's output, in counts.
Fault State
The current state of fault checking for the master encoder
I
The master encoder's index
A
The master encoder's Channel A

The master encoder's Channel B
Ratchet Settings
Ratchet Buffer
The accumulated value, in counts, stored in the buffer when
negative or positive input is set to buffer or unbuffer. This value
is automatically re-set to zero at drive powerup.
Ratchet Output
The position, in counts, generated by the ratchet. This value is
automatically re-set to zero at drive powerup.
Current Position
The position, in counts, generated by the ratchet. This value is
automatically reset to zero at powerup.
Current Velocity
The velocity command, in counts per second, generated by the
ratchet.
