■
Emergency Override
The Emergency Override function ignores faults and alarms that can stop the drive and will force the drive to run with
a set speed or the frequency reference. You can use this function for an applications where it is necessary to continue
the drive operation when there is an emergency situation with the installation, for example, smoke purge.
Emergency Override function will be active when:
• The terminal set for H1-xx = AF or B0 [MFDI Function Selection = Emergency Override FWD or REV] is active
• You set bit 1 in MEMOBUS Register 15FBH for Emergency Override FWD or bit 2 in MEMOBUS register for
Emergency Override REV
If FWD and REV Emergency Override selections are active at the same time, an EF [External Fault] will occur.
The values set in S6-09 [Emergency Override Min Speed] and S6-10 [Emergency Override Max Speed] are the lower
limit and upper limit for the output frequency during Emergency Override. The drive applies upper and lower limit
values to
S6-02 [Emergency Override Ref Selection] .
While the drive is in Emergency Override Mode, the drive records the operation time in U4-61 [Total EMOVR Run
Time] . When the value is more than 60000 min, the alternation timer is at its maximum value. When you set A1-03 =
2220 or 3300 [Initialize Parameters = 2-Wire Initialization or 3-Wire Initialization] to initialize the drive, the drive
will not reset the counter.
Functions Ignored by Emergency Override
When the drive is in factory default setting, Emergency Override ignores these digital inputs:
• Drive Enable
• Drive Enable 2
• Customer Safeties
• BAS Interlock
The drive will give priority to these inputs over Emergency Override when you set S6-08 [EMOVR Drive Enable
Input Mode] , S6-16 [EMOVR Customer Safety Mode] , or S6-17 [EMOVR BAS Interlock Mode] correctly.
