Past trip monitoring  
function 
Stores data on the past eight trips: number of trips that occurred in succession, output frequency, frequency 
command value, forward/reverse run, output current, input voltage (DC detection), output voltage, information on 
input terminals, information on output terminals, and cumulative operation time when each trip occurred. 
Output for frequency 
meter 
Analog output for meter:  1mA dc full-scale dc ammeter  
0 - 20mA (4 to 20mA) output:  DC ammeter (allowable load resistance: 600Ω or less) 
0 - 10V output:  DC voltmeter (allowable load resistance: 1kΩ or more)  
Maximum resolution:  1/1000  
4-digit 7-segments LED  Frequency:  inverter output frequency. 
Alarm:  overcurrent alarm “c”, overvoltage alarm “p”, overload alarm “l”, overheat alarm “h”, 
communication alarm “t”. 
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. 
Indicator 
Lamps indicating the inverter status by lighting, such as RUN lamp, MON lamp, PRG lamp,  lamp, Hz lamp.  
The charge lamp indicates that the main circuit capacitors are electrically charged. 
Environments 
Location of use  Indoors;  not exposed to direct sunlight, corrosive gas, explosive gas, flammable gas, oil mist, or dust; and vibration 
of less than 5.9m/s
2
 (10 to 55Hz). 
Elevation   3000 m or less (current reduction required over 1000 m) Note 3) 
Ambient temperature  -10 to +60°C  Note 4) 
Storage temperature  -25 to +70°C 
Relative humidity  5 to 95% (free from condensation and vapor). 
Note 1.  Maximum output voltage is the same as the input voltage. 
Note 2.  A chattering (momentary ON/OFF of contact) is generated by external factors of the vibration and the impact, etc. In 
particular, please set the filter of 10ms or more, or timer for measures when connecting it directly with input unit 
terminal of programmable controller. Please use the OUT terminal as much as possible when the programmable 
controller is connected. 
Note 3.  Current must be reduced by 1% for each 100 m over 1000 m. For example, 90% at 2000m and 80% at 3000m. 
Note 4.   When using the inverter in locations with temperatures above 40°C, remove the protective label on the top of the 
inverter and use the inverter with the output current reduced according to section 6.18. 
.  To align the inverters side-by-side horizontally, remove the protective label on the top of the inverter before use. When 
using the inverter in locations with temperatures above 40°C, use the inverter with the output current reduced.
