SIMOCODE pro
4-54 GWA 4NEB 631 6050-22 DS 03
4.2.14 "Positioner" control function
Description
SIMOCODE pro can control positioners/actuators with this control function.
The positioner is moved into the corresponding end position with the
"OPEN" and "CLOSE" control commands and is deactivated via its limit
switches (1-active) or torque switches (0-active).
The response of the limit/torque switches must be passed to
SIMOCODE pro via its inputs.
Control commands
• OPEN: Start with "ON >" activates the QE1 contactor control until "End
position OPEN" is reached (Feedback OPEN)
• CLOSE: Start with "ON <" activates the QE2 contactor control until "End
position CLOSED" is reached (Feedback CLOSED)
• Stop with "OFF" deactivates the contactor controls.
The drive remains in the present position.
The control commands can be issued to SIMOCODE pro from arbitrary
control stations (see also the description of "control stations"). Thus, the
inputs (plugs) must be connected to the corresponding sockets, preferably
to the "Enabled control command" sockets.

Switching the direction of travel
The direction of travel can be switched once the "Feedback ON" signal has
expired (motor is switched off) AND the interlocking time has elapsed:
• Via the OFF control command.
SIMOCODE pro prevents both contactors from switching on at the same
time. Switching from one direction of travel to the other can be delayed
via the "interlocking time".
