Digital Speed Selection
Digital Speed Selection utilizes four digital inputs assigned in LI04-11 as Speed
Selection (27) to select up t
o five speeds. Input priority will be I1>I2>...I8. The
input logic table can be defined in LI03 Speed Input Decoding as to which
corresponding speed in the LS parameter group is selected.
The speed profile between selected speeds will be internally generated by the
drive according to the programmed acceleration, deceleration and jerk rates
in the LS parameters group.
The direction is determined by digital inputs assigned in LI04-11 as Up (25)
and Down (26). Both direction signals cannot be signaled simultaneously at
the beginning of a run, otherwise ‘Direction Selection Failure’ will occur.
Binary Speed Selection
Binary Speed Selection utilizes three digital inputs assigned in LI04-11 as
Speed Selection (27) to select up to seven speeds. Input priority will be I1>I2>...
I8. The input logic table can be defined in LI03 Speed Input Decoding and
or Custom Input Decoding LI16 as to which corresponding speed in the LS
parameter group is selected.
The speed profile between selected speeds will be internally generated by the
drive according to the programmed acceleration, deceleration and jerk rates
in the LS parameters group.
The direction is determined by digital inputs assigned in LI04-11 as Up (25)
and Down (26). Both direction signals cannot be signaled simultaneously at
the beginning of a run, otherwise ‘Direction Selection Failure’ will occur.
