3.2 Setting Pulse Output
3.2.2 ON Pulse Width-1 of Electric Energy
[Procedure]
1. Write an ON pulse width-1 of electric energy value to the D register in the table below.
The data type is integer.
2. After writing that value, write “1” to the setting change status register, D0072.
Note
When the value to be set for the ON pulse width-1 is greater than the value calculated by the
following equation, the value cannot be set:
ON pulse width (ms) ≤
Pulse unit [Wh/pls] x 60 x 60 x 1000
Secondary rated power [W] x VT ratio x CT ratio x 1.2 x 2
D Register Reference No. H No. Description Effective Range
D0052 40052 0033
ON pulse width-1 of electric
energy value
1 to 127
Unit: x 10 ms
D0072 40072 0047 Setting change status
If other than 1: Invalid
If 1: Writing is executed
Default value of ON pulse width-1 of electric energy: 5 (50 ms)
[Example]
To set the ON pulse width-1 of electric energy value to 100 ms, write “000A.”
For station number 01, use PC link communication (without checksum) and the random write
command as shown below:
[Command]
[STX] 01010WRW02D0052, 000A, D0072, 0001 [ETX] [CR]
[Response]
[STX] 0101OK [ETX] [CR]
Note
• The ON pulse width-1 of electric energy value can be set for the UPM100 with pulse outputs.
• To set the ON pulse width-1 of electric energy value via communication, set it to 1/10th the
value of the displayed (true) value (e.g., set it to 5 when setting the ON pulse width-1 of electric
energy value to 50 ms).
