Siemens SIMODRIVE POSMO A Function Manual Download Page 44

● myCheckbacks.jogPositiveBusy = TRUE

POSMO A moves in position direction

● myCheckbacks.jogNegativeBusy = TRUE

POSMO A moves in negative direction

The current actual position of POSMO A can be read in the symbol browser in the 

myCheckbacks.actPosition variable.

Note
The "Jog" mode may be terminated only after the POSMO A is stopped (myCommand = STOP)!

"Homing" mode

The "approach using visual axis marking and assign actual value" options have been 

implemented. For homing, POSMO A must be switched to closed-loop control and zero speed. 

The actual value (parameter 40 of POSMO A) can be set via the "Parameter handling", write 

individual parameter operating mode.
In the "Control value" column of the symbol browser, select the check boxes for the following 

variables and select the values to be assigned.

● myCommand = START_HOMING
Clicking Immediate control assigns the value to the variable, and the POSMO A is homed to 

the value set in parameter 40 of POSMO A.

Note
For more information on the homing of the POSMO A, refer to the 

Distributed Positioning Motor 

on PROFIBUS DP user manual.
This documentation is included in the SIMOTION SCOUT scope of delivery as electronic 

documentation!

The current "Homing" state can be read in the symbol browser as follows:

● myCheckbacks.actCommand = HOMING_ACTIVE

Homing activated

● myCheckbacks.actCommand = NO_COMMAND_ACTIVE

myCheckbacks.done = TRUE

Homing completed without error

"MDI" mode

Requirement: The POSMO A is homed!
In the "MDI" mode, one MDI block absolute can be moved.
