Item Explanation Remarks
Fire mode Displays an alarm during running in fire mode (without stopping due to alarm). Fod
Alarm relay output
(for any fault)
• Outputs a relay contact signal if the inverter issues an alarm and stops its output.
•
key or digital input signal RST resets the alarm stop state.
Light alarm (warning)
Upon detection of a failure or warning status that has been defined as a light alarm item, the
inverter displays a light alarm without stopping running.
Light alarm objects
External alarm (OH2), Inverter internal overheat (OH3), Motor overload (OL1), Option
communications error (Er4), Option error (Er5), RS-485 communications error (COM port
1) (Er8), RS-485 communications error (COM port 2) (ErP), Current input wire break
detection (CoF), PID control 1, 2 feedback error detection (PV1, PV2), External PID
control 1, 2, 3 feedback error detection (PVA, PVb, PVC), Dry pump protection (Pdr),
Control of maximum starts per hour (roC), End of curve protection (PoL), Filter clogging
error (FoL), DC fan locked (FAL), Motor overload early warning (OL), Heat sink overheat
early warning (OH), Lifetime alarm (DC link bus capacitor, electrolytic capacitors on
printed circuit boards or cooling fans) (Lif), Reference command loss detected (rEF), Low
torque output (UTL), PTC thermistor activated (PTC), Inverter life (cumulative run time)
(rTE), Inverter life (number of startups) (CnT), PID control 1, 2 alarm (PA1, PA2), External
PID control 1, 2, 3 alarm (PAA, PAb, PAC), Mutual operation slave alarm
(SLA), Low
battery warning (Lob), Date & time information lost (dtL)
Stall prevention
When the output current exceeds the current limiter level during acceleration/deceleration
or running at constant speed, this function decreases the output frequency to avoid an
overcurrent trip.
Retry function
When the inverter has stopped because of a trip, this function allows the inverter to
automatically reset itself and restart. (It is possible to specify the number of retries, the
latency between stop and reset, and target protective functions for retries.)
It is also possible to know how many times retry has been attempted so far via the
communications link.
Target protective functions:
Overcurrent protection (OC1 to OC3), Overvoltage protection (OV1 to OV3), Overheat
protection (OH1, OH3), Inverter overload (OLU), Motor 1 overload (OL1), Motor overheat
(OH4), External alarm (OH2), Undervoltage protection (LV)
Surge protection
Protects the inverter against surge voltages which might appear between one of the power
lines for the main circuit and the ground.
Command loss
detection
Upon detection of a loss of a frequency command (because of a wire break, etc.), this
function issues an alarm and continues the inverter operation at the preset reference
frequency (specified as a ratio to the frequency just before the detection).
Protection
Momentary power
failure protection
If restart after momentary power failure is selected, this function invokes a restart process
when power has been restored within a predetermined period (allowable momentary power
failure time).
Installation location
Shall be free from corrosive gases, flammable gases, oil mist, dusts, and direct sunlight.
(Pollution degree 2 (IEC/EN 60664-1)). Indoor use only.
