Note:
• During Emergency Override, the drive will not prevent oH [Heatsink Overheat] and oH1 [Heatsink Overheat] faults. The drive will Auto
Restart when U4-08 [Heatsink Temperature] is less than L8-02 [Overheat Alarm Level] for oH faults, or the drive Overheat Pre-Alarm
Level for oH1 faults.
• Emergency Override Fault Activation Bits set in S6-11 [EMOVR Drive Protection Fault ON] to S6-14 [EMOVR Application 1 Fault ON]
enable the fault detection for the above functions, if necessary.
During Emergency Override, the drive ignores the alarms in

oH3 [Motor Overheat (PTC Input)]

The drive ignores these alarms, but it enables these MFDO functions during Emergency Override operation:
• H2-xx = B [MFDO Function Selection = Torque Detection 1 (N.O.)]
• H2-xx = 17 [Torque Detection 1 (N.C.)]
• H2-xx = 18 [Torque Detection 2 (N.O.)]
• H2-xx = 19 [Torque Detection 2 (N.C.)]
• H2-xx = 58 [UL6 Underload Detected]
Emergency Override Test Mode
Emergency Override Test Mode lets you test Emergency Override operation while all drive faults stay enabled.
Parameter S6-07 [EMOVR Fault Suppression Mode] controls this function.
To test Emergency Override operation, use this procedure:
1. Set S6-07 = 1 [Test Mode].
The keypad will show an [Emergency Override Test Pending] message.
2. Activate an MFDI terminal set for H1-xx = AF or B0 [Emergency Override FWD or Emergency Override REV].
The drive will start the Test Mode operation. The keypad will show an [Emergency Override Test Mode]
message.
When the Emergency Override MFDI deactivates and the drive fully stops, Test Mode deactivates. Parameter S6-07
then automatically returns to setting 0 [Fault Suppression].
