The drive uses function code 67 (Hex.) and subfunction code 010E (Hex.) to write 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 H5-11: Comm ENTER Command Mode and Enter Command for more information. Table 1.
