Cause
Check the temperature of linear encoder and
contact with the linear encoder
manufacturer.
Check the installation of the linear encoder.
Change the speed of linear encoder within
the range of use.
Take the noise reduction measures.
Contact with the linear encoder
manufacturer.
Adjust the positions of the scale and head.
Change the servo amplifier.
Change the parameter value to within the
setting range.
Change the servo amplifier.
Review the settings of parameter No.PE04,
PE05 (fully closed loop control feedback
pulse electronic gear).Check the installation
of the load side encoder.
Check the installation direction of the load
side encoder.Review the encoder pulse
count polarity selection in parameter No.
PC27.
Review the operation conditions.Review the
setting of parameter No.PE07 (fully closed
loop control position deviation error
detection level) as required.
Review the operation conditions.Review the
setting of parameter No.PE06 (fully closed
loop control speed deviation error detection
level) as required.
