YASKAWA AC Drive GA700 High Performance Type Technical Manual
The drive uses function code 67 (Hex.) and subfunction code 010E (Hex.) to read data with a maximum of 60 holding registers.
You must give the holding register number from which to write separately.
Table 1 shows example messages when you write the frequency reference and torque limit from the drive for slave 1. Table 1 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 Enter Command for more information.
