Chapter 4 Explanation of Functions

4.1.5 Intelligent input terminal status

When the intelligent input terminal status function (d005) is selected, the inverter displays the states of the inputs to the intelligent input terminals.

The internal CPU of the inverter checks each intelligent input for significance, and the inverter displays active inputs as those in the ON state. (*1)

Intelligent input terminal status is independent of the a/b contact selection for the intelligent input terminals. (Example)

FW terminal and intelligent input terminals [7], [2], and [1]: ON

 

Intelligent input terminals [8], [6], [5], [4], and [3]: OFF

(*1)When input terminal response time is set, terminal recognition is delayed. (refer 4.2.79)

4.1.6 Intelligent output terminal status

When the intelligent output terminal status function (d006) is selected, the inverter displays the states of the outputs from the intelligent output terminals.

This function does not monitor the states of the control circuit terminals but monitors those of the outputs from the internal CPU.

Intelligent input terminal status is independent of the a/b contact selection for the intelligent input terminals.

(Example)

Intelligent output terminals [12] and [11]: ON

Alarm relay terminal AL and intelligent output terminals [15] to [13]: OFF

4.1.7 Scaled output frequency monitoring

 

Related code

When the scaled output frequency monitoring (d007) is selected, the

d007: Scaled output frequency monitoring

inverter displays the gain data converted from the output frequency

b086: Frequency scaling conversion factor

with the frequency scaling conversion factor (b086).

Use this function, for example, to change the unit of a value (e.g., motor speed) on display.

Value displayed by function "d007" = "output frequency monitor(d001)" x "frequency scaling conversion factor (b086)"

The frequency scaling conversion factor (b086) can be set within the range 0.1 to 99.9 in steps of 0.1.

(Example) Displaying the speed of a 4-pole motor Speed N (min-1) = (120 x f [Hz])/pole = f (Hz) x 30

As the result of the above calculation with the factor (b086) set to 30.0, the inverter displays "1800" (60 x 30.0) when the output frequency is 60 Hz.

(Display)

0.00to 99.99 in steps of 0.01

100.0to 999.9 in steps of 0.1

1000. to 9999. in steps of 1

1000 to 3996 in units of 10

Note: When you have selected the digital operator as the device to input frequency-setting commands, you can change the output frequency setting by using the and/or key (only while the inverter is operating the motor).

-The change in output frequency made in this mode can be reflected in the frequency setting (function "F001"). Press the STR key to write the new frequency over the currently selected frequency setting. (The precision of the storable frequency data depends on the frequency setting.)

-You cannot change the output frequency while the PID function is enabled or the inverter is not operating the motor.
