7.4 Basic Drive Status
AC Tech register 24 is a 6 word entity containing the drive’s status information. To read the entire status
block use Modbus function code 3 with a length of 6 to read starting at Modbus register number 40025.
The low byte of the third word in this block of data contains the operational status. If this is the only data
you want you can use Modbus function code 3 with a length of 1 to read register 40027.
The value of that low byte of data corresponds to the following operational states:
