3.2.2. Positioning run without loop
The “positioning without loop” mode is used primarily for moving the small distances involved in
fine adjustments. In this case, each position is approached directly.
Note:
To perform a positioning run without a loop, in addition to setting the release (bit 4
in the command byte), you must also set bit
6 (“run without loop”) or ISDU 124 (“loop
length”) must have the value 0.
Note:
In this mode any backlash that might be produced by the driven spindle is NOT
eliminated. For models with an integrated auxiliary gearbox, in this case also the internal
gear backlash does influence the positioning accuracy.
4.2.3
Manual run
The drive can be operated manually (so-
called “manual run”). This helps to simplify
commissioning.
-
Transfer manual run:
Command byte = 0x11 and/or 0x12
Drive begins run
-
End manual run by withdrawing manual run command:
transmit command byte = 0x10
or
Removal of the release
transmit command byte = 0x00
Note:
If a positioning run is required during an active manual run, the drive must be
stopped (reset the release bit). The positioning can be started when the drive is at a
standstill (command byte = 0x14 and required target value).
