oH3
Motor Overheat
The motor overheat signal entered to a multi-function analog input terminal exceeded
the alarm level (H3-02 or H3-10 = E).
oL3
Overtorque 1
Drive output current (or torque in OLV) was greater than L6-02 for longer than the
time set in L6-03.
oL4
Overtorque 2
Drive output current (or torque in OLV) was greater than L6-05 for longer than the
time set in L6-06.
oL5
Mechanical Weakening Detection 1
Overtorque occurred, matching the conditions specified in L6-08.
oS
Overspeed (for Simple V/f with PG)
Pulse input (RP) indicates that motor speed feedback exceeded F1-08 setting.
ov
DC Bus Overvoltage
The DC bus voltage exceeded the trip point.
For 200 V class: approximately 410 V
For 400 V class: approximately 820 V (740 V when E1-01 < 400)
PASS
MEMOBUS/Modbus Comm. Test Mode Complete
PGo
PG Disconnect (for Simple V/f with PG)
Detected when no PG pulses received for a time longer than setting in F1-14.
rUn
Motor Switch during Run
A command to switch motors was entered during run.
SE
MEMOBUS/Modbus Communication Test Mode Error
TrPC
IGBT Maintenance Time (90%)
IGBTs have reached 90% of their expected performance life.
UL3
Undertorque Detection 1
Drive output current (or torque in OLV) less than L6-02 for longer than L6-03 time.
UL4
Undertorque Detection 2
Drive output current (or torque in OLV) less than L6-05 for longer than L6-06 time.
Uv
Undervoltage
One of the following conditions was true when the drive was stopped and a run
command was entered:
• DC bus voltage dropped below the level specified in L2-05.
• Contactor to suppress inrush current in the drive was open.
• Low voltage in the control drive input power. This alarm outputs only if L2-01 is
not 0 and DC bus voltage is under L2-05.
