Note 9: The cumulative operation time increments only when the machine is in operation.

Note 10: At the occurrence of a trip, maximum values are not always recorded and displayed for reasons of detecting time.

Note 11: If there is no trip record, nerr is displayed.

✩Of the items displayed on the monitor, the reference values of items expressed in percent are listed below.

•

Load current:

The current monitored is displayed. The reference value (100% value) is

 

 

 

the rated output current indicated on the nameplate. That is, it

 

 

 

corresponds to the rated current at the time when the PWM carrier

 

 

 

frequency (f300) is 4kHz or less. 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 200 volts for 240V models, 400 volts for 500V models or

 

 

 

575 volts for 600V models. The unit can be switched to V (volts).

5

•

Torque:

The torque generated by the drive motor is displayed. The reference value

 

 

(100% value) is the rated torque of the motor.

 

•

Torque current:

The current required to generate torque is calculated from the load current

 

 

 

by vector operations. The value thus calculated is displayed. The

 

 

 

reference value (100% value) is the value at the time when the load

 

 

 

current is 100%.

 

•

Load factor of inverter:

Depending on the PWM carrier frequency (f300) setting and so on, the

 

 

 

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 (QN).

 

•PBR cumulative load factor: The load factor of the braking resistor that may come up to the level at which an overload trip (QNT) occurs is indicated in percent. An overload trip occurs when it reaches 100%.
