(6) Invalid-parameter alarm when linear motors are used
The following invalid-parameter alarm checks are added when linear
motors are used (they are not issued for rotational motors).
• No separate detector can be used for linear motors. (Full-closed
loop setting results in an alarm being issued.)
* The invalid-parameter alarm detail No. is 10043.
• If no AMR conversion coefficient is set, an alarm is issued.
(Even when the linear encoder is not relocated after the motor is
replaced, the AMR conversion coefficients must be re-set,
because initialization accompanying motor replacement causes
the AMR coefficients to be erased.)
* The invalid-parameter alarm detail No. is 1123.
•
••
• The valid AMR offset data range is below :
-45 (degrees) and +45 (degrees) : (AMR60=0)
-60 (degrees) and +60 (degrees) : (AMR60=1)
If a value out of this range is specified in the parameter, an
invalid-parameter alarm is issued.
* The invalid-parameter alarm detail No. is 1393.
CAUTION
When an AMR conversion coefficient is not set, an
alarm is issued. If it is set, but incorrect, no alarm is
issued. In this case, the linear motor fails to drive
correctly immediately after it passes phase Z. It may
move within one pole-to-pole span (60 mm or 30
mm) in the worst case.
