YASKAWA AC Drive GA700 High Performance Type Technical Manual
The drive uses function code 67 (Hex.) and subfunction code 010D (Hex.) to read data with a maximum of 120 holding registers.
You must give the holding register number from which to read separately.
Table 1 shows example messages when you read the frequency reference and torque limit from the drive for slave 1. Table 1 uses these specified holding registers data for the examples.
0024H:U1-01 [Frequency Reference] = 60.00 Hz (6000 = 1770H)
0028H:U1-09 [Torque Reference] = 100.0% (1000 = 03E8H)
