Speed Reference Command (Offsets 8 ∼∼∼∼ 11)
Unsigned 16-bit value located at parameter 0xFA07. The data contained in the speed reference
command word is the desired speed reference command multiplied by 100, and then converted to
hexadecimal. In other words, if a speed reference command of 55.34Hz is desired, then 55.34 x 100 =
5534, which converted to hexadecimal is 0x159E. The speed reference command low byte (offset 11)
must therefore contain 0x9E and the next-highest byte (offset 10) must contain 0x15.

If the speed reference command exceeds limiting drive parameters (such as the Upper Limit Frequency
or Maximum Frequency), then the drive will ignore it, maintaining its current setting.


Drive Command Scan Data (Offsets 12 ∼∼∼∼ 31)
Table 12 provides a list of the available command scan data selections (selectable via drive parameters
F831

∼F835). The “Parameter” column indicates the drive’s internal parameter to which the

corresponding selection is mapped.

Note 1: Items marked as “RESERVED” in Table 12 are reserved for future use. Selecting
one of the corresponding values as command scan data will have no effect on drive
operation.

Note 2: Although not disallowed, avoid configuring more than 1 scan command data
parameter with the same command data selection (for example, do not set both F831 and
F832 to “3”, etc.). Unexpected drive behavior could result if different data values are
written to the corresponding command locations.

Note 3: Parameters F831

F835 are only validated on drive reset or power-up.

Therefore, if any of these parameters are changed, be sure to reset the drive to validate
the changes.

Note 4: Data range checking is not performed on command scan items. If a value outside
of a specific item’s valid range is written to the drive, that value will be accepted, but
ignored by the drive.
