2.2 Protective functions
1) Retaining alarm signal when auxiliary controll power supply is not used :
If the inverter power supply is cut off while an internal alarm signal is being output, the alarm signal cannot be retained.
2) To issue the RESET command, press the
RESET
key on the KEYPAD panel or connect terminals RST and CM and disconnect them afterwards.
3) Fault history data is stored for the past four trips.

• Stops running to protect inverter from an overcurrent resulting from
overload.
• Stops running to protect inverter from an overcurrent due to a short-circuit
in the output circuit.
• Stops running to protect inverter from an overcurrent due to a ground
fault in the output circuit.
•
Stops running to protect inverter from an overcurrent resulting from ground fault
in the output circuit by detecting zero-phase current. (30kW or larger model only)
• The inverter stops when it detects an overvoltage in the DC link circuit.
(230V : 400Vdc or more, 460V : 800Vdc or more)
• Protection is not assured if excess AC line voltage is applied inadvertently.
• Protects the inverter against surge voltage between the main circuit power line and ground.
• Protects the inverter against surge voltage in the main circuit power line.
• The inverter may be tripped by some other protective function.
•
Stops the inverter when the DC link circuit voltage drops below undervoltage level.
(230V series : 200V DC or less, 460V series : 400V DC or less)
• Alarm signal is not output even if the DC link circuit voltage drops, when “F14 : 3 to 5” is selected.
• The inverter is protected from being damaged when open-phase fault occurs.
• Stops the inverter when it detects excess heat sink temperature in case of cooling fan failure or
overload.
• Stops the inverter when it detects an abnormal rise in temperature in the inverter unit caused by
insufficient ventilation in cubicles or an abnormal ambient temperature.
• Stops the inverter when it detects an abnormal rise in temperature inside the inverter.
• When the built-in or external braking resistor overheats, the inverter stops discharging and running.
• Function data appropriate for the resistor type (built-in/external) must be set. (G11S: 10HP or smaller only)
• This function stops the inverter by detecting an inverter overload.
• This function stops the inverter by detecting an overload in a standard
motor or inverter motor.
• When a blown fuse is detected, the inverter stops running. (40HP or larger model only)
• When an output current exceeds the limit during acceleration, this function lowers output frequency
to prevent the occurrence of an OC1 trip.
• The stall prevention function can be disabled.
• During running in which acceleration is 60s or longer, this function increases the acceleration time to
prevent the occurrence of an OLU trip.
• The acceleration time can be prolonged up to three times the preset time.
• The inverter stops on receiving external alarm signals.
• Use THR terminal function (digital input).
• Stops the inverter when the output frequency exceeds the rated maximum frequency by 20%.
•
If disconnection occurs in pulse generator circuits, the inverter issues an alarm.
• The inverter outputs a relay contact signal when the inverter issued an
alarm and stopped.
• An alarm-stop state of the inverter can be cleared with the RESET key or
by a digital input signal (RST).
• Store up to four instances of previous alarm data.
• The inverter can store and display details of the latest alarm history data.
• The inverter checks memory data after power-on and when the data is written. If a memory error is
detected, the inverter stops.
• If an error is detected in communication between the inverter and KEYPAD when the Keypad panel
is being used, the inverter stops.
• When operated by external signals, the inverter continues running. The alarm output (for any fault) is
not output. Only Er2 is displayed.
• If the inverter detects a CPU error caused by noise or some other factor, the inverter stops.
• If a checksum error or disconnection is detected during communication, the inverter issues an alarm.
•
If a linkage error or other option error is detected, the inverter issues an alarm.
Er6 is indicated only when the inverter is forcedly stopped by [STOP1] or [STOP2] operation in E01 to
E09 (Set value: 30 or 31)
If an unbalance of output circuits is detected during auto-tuning, this function issues an alarm (and
stops the inverter).
• If an RS-485 communication error is detected, the inverter issues an alarm.

• Output terminals:
30A, 30B, and 30C
• Use the RST terminal
function for signal input.
• Even if main power
input is turned off, alarm
history and trip-cause
data are retained.
