Using a PLC as the Command/Reference Source
Using Parameters to Switch Sources
Note:
By setting H1-
= 2, then parameters b1-15 and b1-16 will become enabled when that terminal is switched on.
• Selecting the Run Command Source
Send write data “3” for command code 2181H to the drive or energy-saving unit.
The setting for parameter b1-02 changes to “3”.
• Frequency Reference Source Selection
Send write data “3” for command code 2180H to the drive.
The setting for parameter b1-01 changes to “3”.
• Voltage Reference Source Selection
Send write data “3” for command code 2179H to the energy-saving unit.
The setting for parameter b1-18 changes to “3”.
Using NetRef and NetCtrl
It is also possible to change the source of the frequency reference and the Run command using remote register RW
W2
command code 00FBH.
If the power is shut off, however, the drive will use the original setting for the command/reference source once the power
is turned back again. This method should only be used when briefly switching between command/reference sources.

Drive
• Run Command Source
Table 8 Run Command Source Priority

Dash indicates that the setting has no effect on the source of the Run command.
• Frequency Reference Source
Table 9 Frequency Reference Source Priority
Note: 1.
When the multi-function input terminals are set up for Multi-Step Speed operation, parameters d1-01 through d1-16 take priority as
the source of the frequency reference (assuming that F6-07 = 1).
2.
