Description • The number of lines varies depending on the
options used.
• When the harmonic analysis option is used, the
following line must be installed before the used
command group.
PS1;HA0;OR1;HE1;DF0 <terminator>
• When the D/A output option is used, the
following line must be inserted before the used
command group.
RT0,1 <terminator>
• When the comparator option is used, the
following line must be inserted before the used
command group.
YO0;YM1;DY0;YC1 <terminator>
• When a CM0 is issued, if the shunt current
values or scaling values set for each element
differ from each other, the value set for element
1 will be output.
OY/OY? Sets the relay output items in case of
normal measurement/inquires about the
current setting. Up to four items can be
set.
Syntax OY m1,m2,m3,m4,m5 <terminator>
“m1” indicates the output relay channel
1 ≤ m1 ≤ 4
“m2” indicates the output item number
m2=0 : no output
1 :Voltage (V)
2 :Current (A)
3 :Power (W)
4 :Reactive power (var)
5 :Apparent power (VA)
6 :Power factor (PF)
7 :Input voltage frequency (V Hz)
8 :Input current frequency (A Hz)
9 :Watt-hour (Wh)
10 :Ampere-hour (Ah)
11 :Phase angle (deg)
12 : Peak voltage value (Vpk)*
13 : Peak current value (Apk)*
14 : Computation result (MATH)*
24 :Positive watt-hour (Wh+)
25 :Negative watt-hour (Wh–)
26 :Positive ampere-hour (Ah+)
27 :Negative ampere-hour (Ah–)
* Applies to WT110/WT130 with ROM
version 2.01 or later
“m3” indicates element.
m=1 :Element 1
2 :Element 2 (for model 253503 only)
3 :Element 3 (for WT130 only)
4:∑ (for WT130 only)
“m4” indicates setting value.
0.000 ≤ m4 ≤ ±9999
“m5” indicates prefix
m5=0 :m(E-3)
1 :(E+0)
2 :k(E+3)
3:M(E+6)
Query OY1? <terminator>
Example OY1,1,1,600.0,1
Description • Parameter error 12 will occur if “m” is set to an
illegal value.
• "No output" and "computation result" have no
relation to the element, but when using them
with the "OY" command, set m3=1.
OYH/OYH? Sets the relay output items in case of
harmonic analysis/inquires about the
current setting. Up to four items can be
set.
Syntax OYH m1,m2,m3,m4,m5,m6 <terminator>
“m1” indicates the output relay channel
1 ≤ m1 ≤ 4
“m2” indicates the output item number
m2=0 :no output
1 :Voltage (V)
2 :Current (A)
3 :Power (W)
6 :Power factor (PF)
16 :harmonic distortion factor of voltage
(V THD)
17 :harmonic distortion factor of current
(A THD)
19 :Relative harmonic content of each
voltage component (V %)
20 :Relative harmonic content of each
current component (A %)
21 :Relative harmonic content of each
active power component (W %)
22 :Phase angle between each voltage of
the 2nd to 50 (or 30) th order and the
fundamental (1st order) voltage (V
deg)
23 :Phase angle between each current of
the 2nd to 50 (or 30) th order and the
fundamental (1st order) current (A
deg)
“m3” indicates element.
m=1 :Element 1
2 :Element 2 (for model 253503 only)
3 :Element 3 (for WT130 only)
“m4” indicates order of the harmonic.
m4 = any number between 1 and 50 (or 30)
“m5” indicates setting value.
0.000 ≤ m5 ≤ ±9999
“m6” indicates prefix.
m6=0 : m(E-3)
1: (E+0)
2: k(E+3)
3: M(E+6)
Query OYH3? <terminator>
Example OYH3,3,1,1,1,200,2
Description • Parameter error 12 will occur if “m” is set to an
illegal value.
• “No output” is not related to any element, order
or setting value, so in case the OYH command
is set, set these all to 1 as a dummy.
• “PF”, “VTHD” and “ATHD” are not related to
any order, so in case the OYH command is
used, set 1 as a dummy.
PS/PS? Sets the input as the PLL source/inquires
about the current setting.
