AMIS-30623 LIN Microstepping Motordriver

SetDualPosition

Data Sheet

This command is provided to the circuit by the LIN master in order to perform a positioning of the motor using two different velocities.

See Section

Note1 :

This sequence cannot be interrupted by another positioning command.

Important:

If for some reason

ActPos

equals

Pos1[15:0]

at the moment the

SetDualPosition

command is issued, the circuit will

enter in deadlock state. Therefore, the application should check the actual position by a

GetPosition

or a

command prior to start a dual positioning. Another solution may consist of programming a value out of the stepper motor range for

Pos1[15:0].

For the same reason

Pos2[15:0]

should not be equal to

Pos1[15:0].

SetDualPosition

corresponds to the following LIN writing frame with

0x3C

identifier (type #4).
