the specified target speed (ISDU 142). Drag error correction only takes place
for positioning drives, i.e. not for manual or jog drives. It also only takes effect
during acceleration or a drive at constant speed, not during deceleration. The
speed setpoint for acceleration results from the speed at the start of the
positioning as well as from the specified acceleration (ISDU 147).

Positioning in "Time stamp
”
mode
This mode is active when the orange LED is permanently on with the C/Q
pin open.
(a) Positioning run
- to control the drive, it must first be switched to the IO-Link status "operate".
- disable time stamp (value 0x3FFF = 16383)
- transfer desired setpoint with ISDU 112
- control bits (from the process output data) at 0x03
- time stamp at the desired value, e.g. 10000 (the master now continuously sends new
time stamps, which is why the drive order is never started in this state.)
- disable time stamp (value 0x3FFF = 16383)
The last time stamp remains valid.
Drive starts to move
- Cancellation of drive by withdrawing the release:
Control bits at 0x00 with time stamp 0
drive cancellation is executed immediately
- if a new target position is transferred during the positioning run, the new destination is
approached immediately. If the direction of rotation does not need to be changed, this
is done without interruption.
- if a manual run command is sent during a position run, the positioning run is
interrupted (speed reduced to slow speed) and continued with the manual run.
