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 Table 5.65 when S6-07 = 0:
Table 5.65 Alarms Ignored during Emergency Override
Alarms
bUS [Option Communication Error]
CE [Modbus Communication Error]
dnE [Drive Disabled]
INTLK [BAS Interlock]
oH3 [Motor Overheat (PTC Input)]
oL3 [Overtorque Detection 1]
Alarms
oL4 [Overtorque Detection 2]
SAFE [Customer Safeties]
UL3 [Undertorque Detection 1]
UL4 [Undertorque Detection 2]
UL6 [Underload or Belt Break Detected]
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].
