Possible Causes
Interpolation too low
Evaluation too low
Incorrect input frequency
If using USB counter: Interpola-
tor has a resolution of just 256,
meaning the displayable
resolution is limited to 0.39 µm.
Maximum speed of 3.2 m/s
exceeded
The number on the interface
module does not match the
MINISCALE PLUS carriage
number
The number on the interface
module does not match the
MINISCALE PLUS carriage
number
Digital input has a maximum
input frequency of 500 kHz.
The speed is therefore limited
to 0.2 m/s (or 0.4 m/s) for a
resolution of 0.1 µm.
Incorrect customer-supplied
cable
Further investigation needed
Solution
Increase interpolation
Repeat evaluation 4 times
Adjust frequency to travelling
speed
Use digital interface module
and digital input of the USB
counter (caution: maximum
speed 0.2 m/s)
Limit the speed to 3.2 m/s
Check number relationship
between interface module,
carriages and guideways
Adjust as described in
chapter 6.1
Return the system to
SCHNEEBERGER
System must be returned to
SCHNEEBERGER for
adjustment
For higher speeds, use the
analog interface module and
analog input (caution: maxi-
mum resolution 0.39 µm)
Use a shielded twisted pair
cable
