2.2.2.10
Motor Increment
This parameter is used only for stepper motors and tells the controller how
much the motion device will travel for each motor increment. By increment
we mean one pulse going to the stepper driver, not necessarily a full motor
step. Depending on the type of stepper driver, the motor increment could
be a full step, a half step or a micro-step.
The Motor Increment parameter should reflect the actual stage/driver com-
bination. A wrong setting will cause inaccurate closed-loop operation.
For the PP families, the Motor and the Encoder Increment (resolution) can
be changed separately, on condition that the new value of Motor Increment
would be inferior of the actual value of Encoder Increment.
If you need to change the motor increment setting, press the
key
to modify the current value. Use the numeric keypad to enter the correct
value. Press
to accept the new setting and return to the previous
menu.

key to advance to the next parameter.

2.2.2.11
Encoder Increment
This parameter defines the physical travel of the motion device that corre-
sponds to one encoder count. It represent the resolution of the system and
must reflect the real physical value (theoretical value, excluding all errors).
NOTE
This parameter can be used to correct for a linear error in the motion
device’s absolute position accuracy. See the Motion Control Tutorial sec-
tion for more details.
For the PP families, the Motor and the Encoder Increment can be changed
separatly, on condition that:
• If coder resolution
≥
motor resolution: OK.
• If coder resolution < motor resolution: OK but Motor Resolution = new
coder resolution.
If you need to correct the encoder increment setting, press the
key
to modify the current value. Use the numeric keypad to enter the correct
value. Press
to accept the new setting and return to the previous
menu.

key to advance to the next parameter.
