Parameter name Remarks
0x651E
Command reference channel (the same as function code
P02.02)
0x651F Status word 2 of drive
0x6520
Frequency reference channel (the same as function code
P02.04)
0x6521 Accumulating length (reserved)
0x6522 Motor and mode selection(reserved)
0x6523 Bus voltage at the 3rd fault
0x6524 Actual current at the 3rd fault
0x6525 Operation frequency at the 3rd fault
0x6526 Drive operation status at the 3rd fault
The bit definition is the same as that
of the status word 3.
0x6527 Reserved
0x6528 Status word 3 of drive
Note
1. The status parameter does not support the writing operation.
2. The encoding rules for the slave models are as follows: for the range from 0 to 9999, the hundreds and
thousands are used to identify different drive series, such as AD, MV, etc. The tens and units are used to
identify drive series like 100 Series, 200 Series, 300 Series and 600 Series. For example, the slave model of
ADXXX Series drive is 0*1000+0*100+XXX/10; and the slave model of MVXXX Series drive is
1*1000+0*100+XXX/10.
3. In the status parameter, the maximum length of “actual running value of current main reference”, “current
running frequency”, “running frequency setting” and “running frequency at the 3rd fault” is 32 bits, and for the
others, the length is 16 bits.
The bit definition of the status word 1 of the drive is as shown in the following table:
Bit Value Function Remarks
BIT0
1 Enable serial port control
0 Disable serial port control
BIT1
1 Drive runs
0 Drive stops
BIT2
1 Drive runs reversely
0 Drive runs forward
BIT3 1 Enable serial port reference
