Note 1: Above 40°C: Remove the seal from the top of the inverter and use the inverter with the rated output current reduced.
Note 2: If inverters are installed side by side (with no sufficient space left between them): Remove the seal from the top of
each inverter.
When installing the inverter where the ambient temperature will rise above 40°C, remove the seal from the top of the
inverter and use the inverter with the rated output current reduced.

Switching between standard motor and constant-torque VF motor, switching between motors 1 and 2,
setting of overload trip time, adjustment of stall prevention levels 1 and 2, selection of overload stall
Function of resetting by closing contact 1a or by turning off power or the operation panel. This function is
also used to save and clear trip records.

causes of past trips 1 through 4, parts replacement alarm, cumulative operation time
Stores data on the past four trips: number of trips that occurred in succession, operation frequency,
direction of rotation, load current, input voltage, output voltage, information on input terminals, information
on output terminals, and cumulative operation time when each trip occurred.
Analog output: (1mAdc full-scale DC ammeter or 7.5Vdc full-scale DC ammeter / Rectifier-type AC
voltmeter, 225% current Max. 1mAdc, 7.5Vdc full-scale), 4 to 20mA/0 to 20mA output
Frequency: inverter output frequency.
Alarm: stall alarm "C", overvoltage alarm "P", overload alarm "L", overheat alarm "H".
Status: inverter status (frequency, cause of activation of protective function, input/output voltage,
output current, etc.) and parameter settings.
Free-unit display: arbitrary unit (e.g. rotating speed) corresponding to output frequency.
Lamps indicating the inverter status by lighting, such as RUN lamp, MON lamp, PRG lamp, % lamp, Hz
lamp, LOC/REM key lamp, UP/DOWN key lamp and RUN key lamp. The charge lamp indicates that the
main circuit capacitors are electrically charged.
Indoor, altitude: 1000m (Max.), not exposed to direct sunlight, corrosive gas, explosive gas or vibration
