(M) Monitor display and monitor output signal
104
Power is measured in the range of 0 to 99999.99 kWh, and displayed in five digits. When the monitor value exceeds "999.99", a carry occurs, for
example "1000.0", so the value is displayed in 0.1 kWh increments.
• Digits in the cumulative power monitor can be shifted to the right for the numerical set in
Pr.891 Cumulative power
monitor digit shifted times
.
For example, if the cumulative power value is 1278.56 kWh when
Pr.891
= "2", the operation panel display is 12.78 (display
in 100 kWh increments) and the communication data is 12.
• If the maximum value is exceeded at
Pr.891
= "0 to 4", the monitor value is clamped at the maximum value, indicating that
a digit shift is necessary. If the maximum value is exceeded at
Pr.891
= "9999", the monitor value returns to 0, and the
counting starts again.
• Writing "0" in
Pr.170
clears the cumulative power monitor.
NOTE
• If "0" is written to
Pr.170
, and
Pr.170
is read again, "9999" or "10" is displayed.
Cumulative energization time monitor (Pr.563)
• Cumulative energization time monitor (
Pr.774 to Pr.776
= "20") accumulates energization time from shipment of the
converter unit every one hour.
• If the number of monitor value exceeds 65535, it is added up from 0. Use
Pr.563
to check the numbers of times that the
cumulative energization time monitor exceeded 65535 h.
• Writing "0" in
Pr.171
clears the actual operation time monitor. (The energization time monitor cannot be cleared.)
NOTE
• The cumulative energization time does not increase if the power is ON for less than an hour.
Hiding the decimal places for the monitors (Pr.268)
• The numerical figures after a decimal point displayed on the operation panel may fluctuate during analog input, etc. The
decimal places can be hidden by selecting the decimal digits with
Pr.268
.
NOTE
• The number of display digits on the cumulative energization time (
Pr.774 to Pr.776
= "20") and the cumulative power (
Pr.774
to Pr.776
= "25") does not change.
Minus sign display for the monitors (Pr.290)
• Values with minus signs can be displayed on the monitor indicator of the operation panel. For a list of monitored items that
can be displayed with minus signs, refer to the monitor description list (on
Pr.268 setting
Description
9999 (initial value)
No function
0
For the first or second decimal places (0.1 increments or 0.01 increments) of the monitor, numbers in the first
decimal place and smaller are rounded to display an integral value (1 increments). The monitor value equal to or
smaller than 0.99 is displayed as 0.
1
When monitoring with the second decimal place (0.01 increments), the 0.01 decimal place is dropped and the
monitor displays the first decimal place (0.1 increments). When the monitor display is incremented by one, the
display will not change.
