PRECAUTIONS

Use

the Inverter wlthln the allowable ambient temperature range.

The service life of the inverter depends on ambient temperature.

Ambient temperature should be as low as possible, such that the

allowable range is not exceeded. Care should be taken for installation

direction and the environment.

These parametersrefer to maximum frequency when the Inverter is supplied.

When the inverter is supplied, the inverter output frequency is 60 Hz when the external frequency

reference signal is DC

(1OV)

mA.

However, parameters (see below) that set the

maximum output frequency have a set value over

Hz.

‘

The parameter at shipment

pages 69,70 and 71 of this instruction

manual should be interpreted to

the above.

Note:

adjust the relationship between the frequency reference signal and output frequency, follow the
