• For linear servo motors, use the following equation to determine the proper ERES, based on both the
encoder resolution and the motor's electrical (or magnetic) pitch (DMEPIT).
Example: Linear encoder resolution (post quad) is 1 µm and the electrical
pitch is 42mm (DMEPIT42). ERES is calculated as:

Example (for stepper axis):
SCALE0
; Disable scaling
DEL proga
; Delete program called proga
DEF proga
; Begin definition of program called proga
DRES25000
; Motor/drive resolution set to 25000 steps/rev
; (DRES is used for stepper axes only)
ERES4000
; Encoder resolution set to 4000 post-quadrature counts/rev
; (encoder is for stall detection only)
ESTALL1
; Enable encoder stall detection
MA0
; Incremental mode
MC0
; Preset mode
A10
; Set the acceleration to 10 units/sec/sec
V1
; Set the velocity to 1 unit/sec
D100000
; Set the distance to 100000 units
GO1
; Initiate motion
; Axis will move 100,000 commanded counts (4 revs)
