Checking at error
1
Error in the encoder counting cycle.
Twisting of the linear encoder scale.
Space between the encoder sensor and linear encoder scale.
Contact of the encoder sensor with linear encoder scale.
Presence of damage on the linear encoder scale.
Check the slack of setscrew.
2
Error in linear encoder coordinates after com-
pletion of reciprocating movement.
Checking for twisting of the linear encoder scale.
Checking for a space between the encoder sensor and linear encoder scale.
Checking for contact of the encoder sensor with linear encoder scale.
Checking for the presence of damage on the linear encoder scale.
Check the slack of setscrew.
3
The difference between the motor encoder
value and linear encoder value is large.
If the motor encoder value is larger than the linear encoder value, loosen the
tension of linear encoder scale since it may be too strong.
If the motor encoder value is less than the linear encoder value, strengthen the
tension of linear encoder scale since it may be too loose.
Check the slack of setscrew.
