2.8.2 Warnings (C2D)
A warning does not result in a run being aborted. Run commands continue to be accepted
when warnings are active. The drive issues the following warnings (S-0-0390):
0xC00E2028: Drag error (see Section 3.4)
A new run command deletes this warning.
0xC00E2053: Invalid target value, target value lies outside the permissible positioning range.
A new run command deletes this warning.
0xC00E6043: Upper limit exceeded.
Warning is deleted as soon as the drive is within the permissible positioning range.
0xC00E6044: Lower limit exceeded.
Warning is deleted as soon as the drive is within the permissible positioning range.

Special features
3.1
Positioning
To perform a positioning run, the control word (positioning control) must be written as follows
in the MDT: bit 2-1 = 00 and bit 0 must be toggled. When the run command has been
successfully accepted, the bit 0 in the status word (Producer RTB word container) is toggled in
the AT.
Here are the responses in various situations:
New target value during a run
The new target position is accepted immediately. If a change of direction is required, the drive
brakes using the set deceleration ramp and then approaches the new target value.
Stop command
To perform a stop command, the control word (positioning control) is written as follows in the
MDT: bit 2-1 = 11 and bit 0 must be toggled.
Stop command during a run:
The drive brakes using the maximum possible deceleration ramp.
There will be no readjustment of the position (see also readjustment P-0-0900).
Bit 3 (positioning halt) in the status word (Producer RTB word container) will be set.
Stop command during standstill:
Bit 2 (in position) in the status word (Producer RTB word container) will be set to 0.
There will be no readjustment of the position (see also readjustment P-0-0900).
Toggling bit 0 of the control word (positioning control) in the MDT leads to
the generation of a run command in the drive even if the drive is already at
the target value because the internal resolution is higher. Constant toggling
of bit 0 must therefore be avoided.
Runs, which involve a run to an obstruction (e.g. reference runs to a block),
may only be started with reduced torque (max. run torque < 10% of
nominal torque).
Underwater usage of the PSW is not allowed.
