Alarms Overcurrent, overvoltage, overload, overheat, communication error, under-voltage, setting error, retry in process,
upper/lower limits
Causes of failures Overcurrent, overvoltage, overheat, output short-circuit, ground fault, overload on inverter, arm overcurrent at start-
up, overcurrent on the load side at start-up, CPU fault, EEPROM fault, RAM fault, ROM fault, communication error.
(Selectable: dynamic braking resistor overload, emergency stop, under-voltage, small current, over-torque, low-
torque, motor overload, input phase failure, output phase failure)
Monitoring function Output frequency, frequency command value, operation frequency command, forward/reverse run, output current,
input voltage (DC detection), output voltage, torque, inverter load factor, motor load factor, braking resistor load
factor, input power, output power, information on input terminals, information on output terminals, overload and
region setting, version of CPU1, version of CPU2, PID feedback value, stator frequency, causes of past trips 1to 8,

Past trip monitoring Stores data on the past eight trips: number of trips that occurred in succession, output frequency, frequency
function 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 Analog output for meter:
meter 0 - 20mA (4 to 20mA) output: DC ammeter (allowable load resistance: 600Ω or less)
0 - 10V output:

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.
Indicator
The charge lamp indicates that the main circuit capacitors are electrically charged.
Safety function Safe Torque Off (STO) function according to EN/IEC 61508 SIL2 and ISO 13849-1 category 3 PL"d".
Location of use Indoors; not exposed to direct sunlight, corrosive gas, explosive gas, flammable gas, oil mist, or dust; and vibration
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.
