Description
PLS.UNITS is a bit variable which determines the behavior of the eight PLSs available in the drive. This param-
eter is used to select the units for the PLS pulse.
Examples
Bit Value Behavior
Bit 0 = 0
Position-based PLS handling.
The PLS.STATE parameter displays an active PLS
1 when the position is within the range of PLS.P1 +
PLS.WIDTH1
(PLS.P1 <= PL.FB <= PLS.P1+PLS.WIDTH1).
When the parameter PLS.WIDTH1 has been set to
the value of 0, this bit will be activated as soon as
PLS.FB >= PL.P1.
Bit 0 = 1
Time-based PLS handling.
After PLS.P1 is crossed, the PLS.STATE param-
eter displays an active PLS 1 for a PLS.T1 ms
period of time.
Bit 7 = 0
Position-based PLS handling.
The PLS.STATE parameter displays an active PLS
8 when the position is within the range of PLS.P8 +
PLS.WIDTH8
(PLS.P8 <= PL.FB <= PLS.P8+PLS.WIDTH8).
When the parameter PLS.WIDTH8 has been set to
the value of 0, this bit will be activated as soon as
PLS.FB >= PL.P8.
Bit 7 = 1
Time-based PLS handling.
After PLS.P8 has been crossed. the PLS.STATE
parameter displays an active PLS 8 for a PLS.T8 ms
period of time.
Continuous position-based PLS handling
PLS.P1 = 720
PLS.WIDTH1 = 360
PLS.UNITS bit 0 (for PLS 1) = low; PLS.T1 is not considered.
PLS.EN bit 0 (for PLS 1) = high
PLS.MODE bit 0 (for PLS 1) = low
