Description
0.0–3200.0ms
For pulse string reference only (position control)
Position feedforward filter time constant during
the pulse string positioning.
0.0–3200.0ms
Bit 0: Positioning mode selection
0: Relative position
1: Absolute position (Origin mode. This function
is reserved.)
Bit 1: Cyclic positioning setting. You can enable
positioning through a terminal (function 55) or
choose automatic cyclic positioning. Terminals
support only the enabling of continuous
positioning, and automatic cyclic positioning
can be set to cyclic positioning or reciprocating
positioning through bit 2 of P21.16.
0: Terminal-based cyclic positioning
1: Automatic cyclic positioning
bit2: Cyclic mode
0: Continuous
1: Reciprocating (support the automatic cyclic
positioning)
Bit 3: P21.17 digital setting mode. You can
select incremental or position type. The
incremental type indicates that P21.17 needs to
be conducted again after each positioning is
enabled. When the position reference bit
command is enabled, the displacement is set
through P21.17. When P21.17 is changed, new
position is be positioned automatically.
0: Incremental
1: Position type (do not support the continuous
mode)
bit4: Origin searching mode
0: Search for the origin only for once
1: Search for the origin in every time of running
bit5: Origin calibration mode
0: Calibration in real time
1: One-time calibration
