Chapter 4 Explanation of Functions<br />

4.1.14 Cumulative power monitoring<br />

When the cumulative power monitoring function is selected, the inverter<br />

displays the cumulative value of electric power input to the inverter.<br />

You can also convert the value to be displayed to gain data by setting<br />

the cumulative input power display gain setting (b079).<br />

Related code<br />

d015: Cumulative power monitoring<br />

b078: Cumulative power clearance<br />

b079: Cumulative input power display<br />

gain setting<br />

Value displayed by function "d015" = "calculated value of input power (kW/h)"/"cumulative input power<br />

display gain setting (b079)"<br />

The cumulative power input gain can be set within the range 1 to 1000 in steps of 1.<br />

You can clear the cumulative power data by specifying "01" for the cumulative power clearance function<br />

(b078) and pressing the STR key.<br />

You can also clear the cumulative power data at an intelligent input terminal by assigning function "53"<br />

(KHC: cumulative power clearance) to the intelligent input terminal.<br />

When the cumulative input power display gain setting (b079) is set to "1000", the cumulative power data<br />

up to 999000 (kW/h) can be displayed.<br />

(Display)<br />

0.0 to 999.9 in steps of 1 kW/h, or the unit set for function "b079"<br />

1000 to 9999 in units of 10 kW/h, or the unit set for function "b079"<br />

⎡100 to ⎡999 in units of 1000 kW/h, or the unit set for function "b079"<br />

4.1.15 Cumulative operation RUN time monitoring<br />

When the cumulative operation RUN time monitoring function (d016) is<br />

selected, the inverter displays the cumulative time of the inverter<br />

operation.<br />

(Display)<br />

0. to 9999. in units of 1 hour<br />

1000 to 9999 in units of 10 hours<br />

⎡100 to ⎡999 in units of 1,000 hours<br />

4.1.16 Cumulative power-on time monitoring<br />

When the cumulative power-on time monitoring function(d017) is selected,<br />

the inverter displays the cumulative time throughout which the inverter<br />

power has been on.<br />

(Display)<br />

0. to 9999. in units of 1 hour<br />

1000 to 9999 in units of 10 hours<br />

⎡100 to ⎡999 in units of 1,000 hours<br />

4.1.17 Heat sink temperature monitoring<br />

When the heat sink temperature monitoring function (d018) is selected,<br />

the inverter displays the temperature of the internal heat sink of the<br />

inverter.<br />

(Display)<br />

0.0 to 200.0 in steps of 0.1 °C<br />

4.1.18 Motor temperature monitoring<br />

Related code<br />

When the motor temperature monitoring function is selected, the inverter d019: Motor temperature monitoring<br />

displays the temperature of the thermistor connected between control<br />

b098: Thermistor for thermal<br />

protection control<br />

circuit terminals TH and CM1.<br />

Use the thermistor model PB-41E made by Shibaura Electronics Corporation.<br />

Specify "02" (enabling NTC) for the thermistor for thermal protection control (function "b098").<br />

(Display)<br />

0.0 to 200.0 in steps of 0.1 °C.<br />

Note: If "01" (enabling PTC) is specified for the thermistor for thermal protection control (function "b098"),<br />

motor temperature monitoring is disabled.<br />
