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. Above 50°C: Use the inverter with the output current reduced.
. Side by side installation (with no space between inverters): Use the inverter with the output current reduced.

Stall prevention, current limitation, over-current, output short circuit, over-voltage, over-voltage limitation,
undervoltage, ground fault detection, input phase failure, output phase failure, overload protection by electronic
thermal function, armature over-current at start-up, load side over-current at start-up, over-torque, undercurrent,
overheating, cumulative operation time, life alarm, emergency stop, various pre-alarms
Switching between standard motor and constant-torque VF motor, switching between motors 1 & 2, setting of
overload trip time, adjustment of stall prevention levels 1 & 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.
Overcurrent, overvoltage, overload, overheat, communication error, under-voltage, setting error, retry in process,
upper/lower limits
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, motor
overload, input phase failure, output phase failure)
Operation frequency, operation frequency command, forward/reverse run, output current, input voltage (DC
detection), output voltage, torque, load factor of inverter, 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, frequency command (after compensation), causes of past trips 1to 8, parts replacement alarm, cumulative
operation time
Stores data on the past eight trips: number of trips that occurred in succession, operation frequency, operation
frequency command, 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.
Analog output for meter: 1mA dc full-scale dc ammeter
0 - 20mA (4 to 20mA) output: DC ammeter (allowable load resistance: Less than 750Ω)
0 - 10V output: DC voltmeter (allowable load resistance: Over 1kΩ)
Resolution: Maximum of 1/1000
Frequency: inverter output frequency.
Alarm: stall 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.
Lamps indicating the inverter status by lighting, such as RUN lamp, MON lamp, PRG lamp,  lamp, Hz lamp, EASY
lamp, CANopen lamp, NET lamp. The charge lamp indicates that the main circuit capacitors are electrically charged.
