• Deactivated:
Safety-oriented tripping via the DM-F module also affects the
SIMOCODE pro control function, so that the contactor control is
always tripped, too.
This setting is selected for applications where safety-oriented
tripping directly affects the motor controlled by SIMOCODE pro.
• Activated:
Safety-oriented tripping via the DM-F module does not affect the
SIMOCODE pro control function, so that the contactor control is
not tripped.
This setting is selected for applications where safety-oriented
tripping does not affect the motor controlled by SIMOCODE pro.
You can choose between:
• Motor
• Resistive load (e.g. heating):
Because generally no overcurrent flows in a resistive load during
switching on, the "Start active" status is not signaled. In this
case, the start-up override does not occur for the "Signaling",
"Warning" and "Tripping" functions.
SIMOCODE pro monitors the status of the feeder (ON or OFF) via
FB ON.
If the status of FB ON changes without a corresponding switching
command, "Fault - Feedback (FB)" switches off the feeder.
Default: 0.5 s.
The feedback time can be used to suppress such "feedback faults"
for a defined period of time, e.g. in the case of network
switches.When the motor is switched off,
SIMOCODE pro continuously checks if FB ON = 0. If the current
flows longer than the set feedback time without the "ON" control
command being issued, a fault message "Trip - Feedback (FB) ON"
is issued. The contactor controls can only be connected after the
fault has been rectified.
When the motor is switched on, SIMOCODE pro continuously
controls if FB ON = 1. If no current flows for longer than the set
feedback time without the "OFF" control command being issued, a
fault message "Trip - Feedback (FB) OFF" is issued. The contactor
controls are deactivated.
SIMOCODE pro monitors switching on/switching off. Switching on/
switching off must be completed within this time period.
Default: 1.0 s.
After the "ON" control command is issued, SIMOCODE pro must be
able to detect current in the main circuit within the execution time.
Otherwise, the fault message "Trip - Execution ON command" will
be issued. SIMOCODE pro deactivates the contactor controls.
After the "OFF" control command is issued, SIMOCODE pro must
not be able to detect any current in the main circuit after the
execution time has elapsed. Otherwise, the fault message "Trip -
Execution STOP command" will be issued. The contactor controls
can only be connected after the fault has been rectified.
