Command Name

Move to Absolute Step

 

 

 

 

 

 

 

Command Format

30h HIGH_BYTE LOW_BYTE

 

 

 

 

 

Description

The Move to Absolute Step command sets the position of the stepper motor. The valid

 

 

range is 0 - 3200, written in a 2-byte (16-bit) format.

 

 

 

 

Example

The following example converts a integer decimal step to a HIGH_BYTE-LOW_BYTE

 

 

format:

 

Convert decimal step number to hexadecimal.

 

 

1.

2485 = 0B1Dh

 

 

2.

HIGH_BYTE = 0Bh

Convert to HIGH_BYTE and LOW_BYTE format.

 

 

 

LOW_BYTE = 1Dh

Description

The Query Current Step command returns the current location of the stepper motor as

 

 

a 2-byte (16-bit) value.

 

 

 

 

 

Example

The following example shows how to translate the HIGH_BYTE-LOW_BYTE

 

 

returned value into a integer decimal step number:

 

 

1.

0Bh & 1Dh = 0B1Dh

HIGH_BYTE and LOW_BYTE value to

 

 

 

 

hexadecimal value.

 

 

2.

0B1Dh = 2845

Convert hexadecimal value to an integer decimal

 

 

 

 

value.
