Example: Incremental encoder / 2500 increments/ 4-fold evaluation
One application would be, e.g., a drill for which the chuck key must always have a dened position during
standstill.
7.12.4.12 Posi mode / remaining distance positioning
The remaining distance positioning is similar to the mode dened stop. Only that here, positioning is done to a
set distance from a marker, rather than to a dened position within one revolution.
The drive leaves the speed-controlled operation and runs, starting at a marker, the adjusted residual distance.
To that end, the value 2: relative must be set in PS.27.
PS.27: Index mode
Bit Meaning Value Explanation
1..3 Position setting 2: relative
The value of PS.24 index / position denes the path that still has to
be travelled starting at the positive edge of the marker.
After activation of the positioning mode by a digital input, the drive remains in vector controlled operation,
until the marker triggers a "start positioning" command. The target position for the positioning is the actual po-
sition ru.54 at the time of the positive edge + PS.24 "index/position".
ru.61: target position
ru.54: actual position
