9-7. Details of Commands
9-7-1. Setting unit to be controlled
・
This command specifies a power supply unit to be controlled when the IF-41GU/IF-41USB is used.
PW
**
**:
0
、
1 to 32
Specify the system address of a power supply unit to be controlled. When the value of 0 is
specified (broadcast specification), all power supply units connected with a specified local bus
master are controlled. When the power is turned on, 0 (broadcast) is selected.
<Precautions>
・
It is possible to control several units using the IF-41GU/IF-41USB by writing their addresses in a
line using the PW command. The PW command is executed earlier than any other commands.
< Example 10> PW1, PW2, PW31, SW1 ... These commands turn on the MAIN OUTPUT keys of
three PW-A power supply units of addresses 1, 2 and 31. If PW1, PW2, SW1,
PW31, SW0 are specified, the SW1 and SW0 commands are sent to the PW-A
power supply units of addresses 1, 2 and 31. As a result, the MAIN OUTPUT keys
of three units are turned off (SW0).
9-7-2. Setting voltage or current
・
These commands set the voltages and currents of PRESET 1 to PRESET 4. If the PW-A power
supply unit is turned off and turned on then, the voltages and currents set in PRESET 1 to
PRESET 4 are lost, since these commands do not store the set values. Execute the MW1
command shown in “9-7-18.” to store values in PRESET 1 to PRESET 4.
