Troubles
Actual spacing between
characters is larger or
small than setting.
Causes
Pulse setting of encoder is not
correct.
Either A or B phase signal is
refused. (A and B phase used)
Measured number of encoder
pulses differs from calculated
one.
ME-LPMSZ-OP-7
Measures
Check setting to be sure that:
• When using A phase only:
Number encoder pulses = Number of pulses/mm x 2
• When using A and B phases:
Number encoder pulses = Number of pulses/mm x 4
Check that signal is applied to A and B phase terminals
of encoder.
Increase or decrease values in "Encoder fine adjustment"
field as appropriate.
• When the character interval is wide:
Increase the setting.
• When the character interval is narrow:
Decrease the setting.
