Note 1 : The parameter values can be in integer, decimal and
negative. Each value has different process to read and
write.
Refer to 8-1 lists to find out the minimum unit and value
range for each parameter.
a. In computer command message D5 80, this value
is negative.
b. In drive response message,
Function code 03H : D(4+2n) 80, this value is
negative.
Function code 06H, 08H : D(3+2n) 80, this value
is negative.
All hexadecimal values have 4 numbers(note2~4), first
two numbers are D4, last two numbers are D5.
Note 2 : Processing integer number
Transfer value into hexadecimal value. The first two
numbers are D4 and the last two numbers are D5.
Ex. Speed=1710 rpm
1710(decimal)=06AE(hexadecimal)
D4=06H
D5=AEH
Note 3 : Processing decimal number
Using following methods to process if the minimum
parameter value is decimal number.
Minimum unit by 1
st
decimal number : The original value
times 10 to be a new number.
Then,
Use this new number to tansfer value into hexadecimal
value.
The first two numbers are D5 and the last two numbers
are D6.
Ex. Acc. time CD08=60.0 sec
60.0
× 10=600(decimal)=0258(hexadecimal)
D4=02H
D5=58H
The value needs to divide by 10 when it returns to
original shape.
