The number of bytes set within the response message sets twice the number of data contained in the command message. The response
message uses the same formula.
Writing to Non-Consecutive Holding Registers
You can separately write the specified data to a maximum of 60 holding registers that uses function code 67
(Hex.) and subfunction code 010E (Hex.) .
You must give the holding register number from which to write separately.
Table 5.8
shows example messages when you write the frequency reference and torque limit from the drive for
slave 1.
Table 5.8
uses these specified holding registers data for the examples.
• 0002H: Frequency Reference = 60.00 Hz (6000 = 1770H)
• 0004H: Torque Limit = 150.0% (1500 = 05DCH)
When you rewrite the parameter value with the write command through the H5-11 [Comm ENTER Command
Mode] setting, you must use the Enter command to save and enable the contents of the changes. Refer to
Comm ENTER Command Mode on page 929
