Example: Starting from the soft starter of standing 02, the controller sends 02 06 00 01 00 01,
such as command execution, normal return 02 06 00 01 00 01.Starter can normal starting to view
the status register, if there is a failure, should send 02 06 00 01 00 04 to reset
0002 Status register
For example: Read the status register code, send 02 03 00 02 00 01, if the starter is starting to
return to the 02 03 02 00 01. If the starter fails, it returns 02 03 02 00 08.
0003 current average (sixteen decimal)
The average *10 value of the value to the actual current of motor phase (including a decimal).
For example: Read the current size, send 02 03 00 03 00 01, if the current 235A, then return
02 03 02 09 2E (return value /10 for actual current value).
0004 fault code (sixteen hex)
When the state register0002 3 to 1, on behalf of the soft starter in fault state.
For example: Send 02 03 00 04 00 01, if returned 02 03 02 00 04, explain the current input
missing phase (fault code 04).
Function parameter register 0XXX 5200 soft starter
0256-0274 for the function register, corresponding to the address is 0x0100-0x0112, the high
byte address is 01, the status byte address is 0x00-0x12, corresponding to the function code P0-PL.
For example, address P9 and function code 0x109 (starting mode). Can read and write the code.
The following examples illustrate their usage:
Example 1: Read the size of the function code P1, send 02 03 01 01 00 01.
Example 2: Read the function code PA (protection level), send 02 03 01 0A 00 01, if return 02
03 02 00 03, the reading of the protection level is 3.
Example 3: Soft starter will rewrite the function code P7 70%, send 02 03 01 07 00 01.
