5. PARAMETERS
5.4 (M) Item and output signal for monitoring
• When
Pr.891
= "0 to 4", the meter stops at the maximum number. When
Pr.891
= "9999" and the cumulative energy
reaches more than the upper limit of readout, cumulative value is reset to 0 and the metering restarts.
• Writing "0" in
Pr.170
clears the cumulative power monitor.
NOTE
• When
Pr.170
is read just after "0" has been written in
Pr.170
, the setting "9999" or "10" is displayed.
Monitoring cumulative energization time (Pr.563)
• Cumulative energization time monitoring (
Pr.774 to Pr.776
= "20") accumulates energization time from shipment of the
converter unit every hour.
• When the cumulative energization time counter reaches 65535, it starts from 0 again. The number of times the cumulative
energization time counter reaches 65535 can be checked with
Pr.563
.
• Setting "0" in
Pr.171
clears the actual operation time meter. (The cumulative energization time meter cannot be cleared.)
NOTE
• The cumulative energization time does not increase if the power is turned OFF after 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.
Enabling display of negative numbers during monitoring (Pr.290)
• Negative values can be used for indication on the operation panel. To check which items can be monitored with indication
of negative numbers, refer to the monitor items list (on
—: Negative numbers indication disabled (positive only)
5.4.2
Output terminal function selection
Use the following parameters to change the functions of the open collector output terminals and relay output terminals.
Pr.268 setting
Description
9999 (initial value) Function disabled.
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 monitoring with the
first decimal place, the display will not change.
