(oldest trip record). If no trip occurred in the past, the message " " will be displayed. Details on
past trip record 1 to 8 can be displayed by pressing the center of the setting dial when past trip 1 to 8 is

temperature specified using , the ON time of the inverter, the operating time of the motor and the
output current (load factor). Use this alarm as a guide only, since it is based on a rough estimation.
Output current:
The current monitored is displayed in percentage. The value indicated on the
nameplate is 100%. The unit can be switched to A (amperes).
Input voltage:
The voltage displayed is the voltage determined by converting the voltage
measured in the DC section into an AC voltage. The reference value (100%
value) is 200V (240V class), 400V (500V class). The unit can be switched to V
(volts).
Output voltage:
The voltage displayed is the output command voltage. The reference value
(100% value) is 200V (240V class), 400V (500V class). This unit can be
switched to V (volts).
Depending on the PWM carrier frequency ( f300 ) setting and so on, the
Load factor of inverter:
actual rated current may become smaller than the rated output current
indicated on the nameplate. With the actual rated current at that time (after a
reduction) as 100%, the proportion of the load current to the rated current is
indicated in percent. The load factor is also used to calculate the conditions
for overload trip ( ).
