SIMOTRAS HD Operating Instructions
9.11 Automatic
restart
The "Automatic restart" function is controlled by the setting in parameter P086:
P086 = 0
No automatic restart
P086 = 0.1s to 2.0s
”Automatic restart" in seconds
The purpose of the "Automatic restart" function is to prevent the SIMOTRAS converter from switching
immediately to the "FAULT" state, but allow it to return to the "Run" state after the elimination of certain
fault conditions such as brief failures in supply voltages, brief undervoltage or overvoltage, excessively
high or low line frequencies.
The appropriate fault message is output only if one of the following fault conditions prevails
continuously for longer than the "Automatic restart time" set in P086 (maximum time delay within which
fault condition must be eliminated for "Automatic restart"):
F001 Failure of electronics supply in operation (5U1, 5W1)
F004 Phase failure in the supply to the power section (1U1, 1V1, 1W1)
F006 Undervoltage in the supply to the power section
F007 Overvoltage in the supply to the power section
F008 Mains frequency below 45Hz
F009 Mains frequency above 65Hz
When one of the fault conditions associated with faults F004, F006, F008, F009 is active and the
automatic restart time delay is still running, the converter dwells in operating state 04.0.
Failures in the electronics supply lasting up to several 100 ms are bridged by the back-up power
supply. With longer failures, the failure time is measured by measuring the voltage across one
"discharge capacitor" and, if the failure has not lasted as long as the "Restart time" set in P086, the
converter restarted again immediately provided that the corresponding control signals (e.g. "Switch-
on", "Operating enable") are still applied.
When the "Switch-on", "Shutdown" and "Crawl" functions are edge-triggered (see P445 = 1), the
converter cannot be restarted automatically after the power supply backup has been used.
