oH5

Motor Overheat (NTC Input)
The motor temperature exceeded the level set to L1-16 (or L1-18 for motor 2)

<1> Detected in models 4A0930 and 4A1200.

oL3

Overtorque 1
Drive output current (or torque in OLV, CLV, AOLV/PM, and CLV/PM) was greater than L6-02 for longer

than the time set to L6-03.

oL4

Overtorque 2
Drive output current (or torque in OLV, CLV, AOLV/PM, CLV/PM) was greater than L6-05 for longer than

the time set to L6-06.

oL5

Mechanical Weakening Detection 1
Overtorque occurred, matching the conditions specified in L6-08.

Overspeed
The motor speed feedback exceeded the F1-08 setting.

DC Bus Overvoltage
The DC bus voltage exceeded the trip point.
• For 200 V class drives: approximately 410 V
• For 400 V class drives: approximately 820 V (740 V when E1-01 is less than 400)
• For 600 V class drives: approximately 1040 V

PASS

MEMOBUS/Modbus Comm. Test Mode Complete

PGo

PG Disconnect (for Control Mode with PG)
Detected when no PG pulses are received for a time longer than setting in F1-14.

PGoH

PG Hardware Fault (detected when using a PG-X3 option card)
PG cable has become disconnected.

rUn

Motor Switch during Run
A command to switch motors was entered during run.

MEMOBUS/Modbus Communication Test Mode Error

Note:

This alarm will not trigger a multi-function output terminal that is set for alarm output

(H2-oo = 10).

<1>

THo

Thermistor Disconnect
The thermistor used to detect motor temperature has become disconnected.

<1> Detected in models 4A0930 and 4A1200.

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, CLV, AOLV/PM, and CLV/PM) less than L6-02 for longer than

L6-03 time.

UL4

Undertorque Detection 2
Drive output current (or torque in OLV, CLV, AOLV/PM, and CLV/PM) less than L6-05 for longer than

L6-06 time.

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 opened.
• 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.
