Operation

 

 



The running frequency is displayed.(If the monitor display mode

 

 

setting parameter  is set at . [Running frequency])

 

 

 

 

 

MON



Press the MON key to call up the first basic parameter

 

(automatic acceleration/deceleration).

 

 

 

 

 

 

 

 

 

 

 

 

 

 



Select  by pressing the or key.

 

 

 

 

 

 

 

 

 

 

ENT

 



Press the Enter key to display the parameter .

 

 

 

 

 

 

 

 

 

 



Select the terminal AM terminal meter selection parameter

 

 by pressing key.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

ENT

Press the Enter key to display the parameter setting

 

(set value).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 



Set the parameter at  (fixed output for meter

 

 

calibration) by pressing the key.

 

 

 

 

 

 

 

 

 

 

 

 

 

ENT



Press the Enter key to save the change. Then,

 

 

 

 

 and the set value are displayed alternately.

 

 



Select the AM terminal meter sdjustment  by

 

 

pressing key.

 

 

 

 

 

 

 

 

 

 

 

 

 

ENT



Press the Enter key to switch to the data display mode.

 

 

 

 

 

 

 

 

 

 

 

 

 

Calibrate the meter by pressing the or key. Adjust

 

 

 

 

the pointer to the graduation to which you want it to point

 

 

 

 

when the inverter passes a current 150% larger than its

 

 

 

 

rated output current.

 

 

(Note that the meter reading varies during adjustment,

 

 

 



though the reading in the digital LED (monitor) on the

 

 

 

control panel does not change.)

 

 

 

 

 

 

 

 

 

 

 

[Point] Holding down the key for several

 

 

 

 

 

 

 

 

seconds facilitates this adjustment.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

By setup, before the needle of meter begins to sway,

 

 

 

 

it will take time.

 

ENT

 



Press the Enter key to save the setting. Then,  and

 

 

 

 

the set value are displayed alternately.

 

 



Select the terminal AM terminal meter selection parameter

 

 

 

 

 

 

 

 

 by pressing key.

 

ENT

 



Press the Enter key to display the parameter setting.

 

 

 

 

 

 

Return the parameter setting to  (output current display).

 

ENT

 

 

Press the Enter key to save the change. Then,  and

 

 



the newly-set value are displayed alternately.

 

 

 

 

 

 

 

 

 

 

MON

 

 

Press the Monitor key three times to return to the running

 

 



frequency display mode.(If the monitor display mode setting

 

 

 

 

 is set at [Running frequency])
