Description
Deactivated (default setting): Safety-related tripping via the DM-F modules
•
also affects the SIMOCODE pro control function, so that the contactor
control is always tripped, too. This setting is selected for applications
where safety-related tripping directly affects the motor controlled by
SIMOCODE pro.
Activated: Safety-related tripping via the DM-F modules does not affect the
•
SIMOCODE pro control function, so that the contactor control is not
tripped. This setting is selected for applications where safety-related
tripping does not affect the motor controlled by SIMOCODE pro.
You can select from the following:
Motor (default)
•
Resistive load (e.g. heater): Since overcurrent generally does not flow
•
during start-up on a resistive load, the "Start active" status is not signaled.
In this case, the startup override does not occur for the "signal," "warn,"
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 setting: 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 switchover.
When the motor is switched off, SIMOCODE pro continuously checks whether
FB ON = 0. If the current flows longer than the set feedback time without the
"ON" control command being issued, a fault message "Fault - 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 checks whether
FB ON = 1. If no current flows for longer than the set feedback time without
the "OFF" control command being issued, a fault message "Fault - feedback
(FB) OFF" is issued. The contactor controls are deactivated.
SIMOCODE pro monitors the switch-on and switch-off process. The switch-on
or switch-off process must be completed within this time.
Default setting: 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 "Fault - 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 current in the main circuit after expiry of the execution time.
Otherwise, the fault message "Fault - Execution OFF command" will be
issued. The contactor controls can only be connected after the fault has been
rectified.
SIMOCODE pro prevents, e.g. in the case of reversing starters, both
contactors from switching on at the same time. Changing from one direction of
rotation to the other can be delayed via the interlocking time.
Default setting: 0 s.
