Length in bit11~bit0 represented by binary system, is to the maximum 2048 seconds, and bit15~bit14 is binary one 0, then motor stops
Only the time is in unlimited time, and binary system can be ignored in bit11~bit0, bit15~bit14 be binary one 1, then motor control with
Millisecond carrys out timing, and the time of stopping is the length in bit11~bit0 represented by binary system, is 2048 milliseconds to the maximum, but need
Reset the initial value of meter reading address.
9. DC motor control method as claimed in claim 5, it is characterised in that the motor speed governing, is read by identification
Double control byte, as long as bit13~bit12 is binary one 1, then it is assumed that be motor speed governing, bit15~bit14 is binary system
00, then the time of motor speed governing carry out timing for millisecond, the length of time of speed governing represented by binary system in bit7~bit0, most
Greatly 256 milliseconds, bit15~bit14 is Binary Zero 1, then the time of motor speed governing carry out timing for the second, the time of speed governing is
Length in bit7~bit0 represented by binary system, is to the maximum 256 seconds, and bit15~bit14 is binary one 0, then motor speed governing
Function is locked, and bit15~bit14 is binary one 1, then motor control carrys out timing with millisecond, and the time of operation is bit7~bit0
Length represented by interior binary system, is 256 milliseconds to the maximum, however it is necessary that resetting the initial value of address.Wherein the two of bit11~bit8
Binary data is speed governing step value (1~15), and bit7~bit0 binary systems are motor stepping time, coordinate bit15~bit14 to come
Millisecond or second stepping are done, by increasing or reducing motor stepping and governing time, speed-raising or the reduction of speed of motor can be easily realized.
