Faults
oL1 [Motor Overload]
oL2 [Drive Overloaded]
oL3 [Overtorque Detection 1]
oL4 [Overtorque Detection 2]
oL7 [High Slip Braking Overload]
oPr [Keypad Connection Fault]
oS [Overspeed]

PE1 [PLC Fault 1]
PE2 [PLC Fault 2]
PF [Input Phase Loss]
TiM [Keypad Time Not Set]
UL3 [Undertorque Detection 1]
UL4 [Undertorque Detection 2]
UL6 [Underload or Belt Break Detected]
Uv1 [DC Bus Undervoltage]
VLTS [Thermostat Fault]
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
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]
.
