Switching Function M99 (Pin 10); Examples - Siemens SIMATIC S5 Manual

Technical Description of the IP 266
Exceptions
A large non-compensated drift or a large load may result in the setpoint reaching
the target position while the actual value remains outside zero-speed monito-
ring. If the maximum following error is not exceeded in the process, the IP 266
sets and starts a 5s watchdog timer. When no movement toward the target is
detected within this time period, the IP 266 terminates the operation with
"Target position not reached".
The "Position Reached" signal is not generated.

Switching Function M99 (Pin 10)

So-called M functions can be programmed in a machining program (see Sec-
tion 5.4). These functions are returned to the PLC in the form of numerical values.
One of these functions (M99) is also applied to an output; this signal can be used
to execute program-controlled switching operations (for example, enabling
another module).
