Instruction

Interpretation

TE

Tell error - all axes

TE X

Tell error - X axis only

TE Y

Tell error - Y axis only

TE Z

Tell error - Z axis only

TE W

Tell error - W axis only

Example 6 - Absolute Position

Objective: Command motion by specifying the absolute position.

Instruction

Interpretation

DP 0,2000

Define the current positions of X,Y as 0 and 2000

PA 7000,4000

Sets the desired absolute positions

BG X

Start X motion

BG Y

Start Y motion

After both motions are complete, the X and Y axes can be command back to zero:

PA 0,0

Move to 0,0

BG XY

Start both motions

Example 7 - Velocity Control

Objective: Drive the X and Y motors at specified speeds.

Instruction

Interpretation

JG 10000,-20000

Set Jog Speeds and Directions

AC 100000, 40000

Set accelerations

DC 50000,50000

Set decelerations

BG XY

Start motion

after a few seconds, command:

JG -40000

New X speed and Direction

TV X

Returns X speed

and then

 

JG ,20000

New Y speed

TV Y

Returns Y speed

These cause velocity changes including direction reversal. The motion can be stopped with the instruction

STStop

Example 8 - Operation Under Torque Limit

The magnitude of the motor command may be limited independently by the instruction TL.

Instruction

Interpretation

TL 0.2

Set output limit of X axis to 0.2 volts

JG 10000

Set X speed

BG X

Start X motion
