3. Operation
225
1) Stop the operation. (Calibration is disabled during axis motion, pressing or pause. If
calibration signal CLBR is set to ON, alarm 0E1 “Loadcell calibration error” occurs.)
2) Turn loadcell calibration signal CLBR ON.
3) At the completion of calibration, calibration complete signal CEND is turned ON. Set the
CLBR signal to OFF.
Unless calibration ends normally, alarm 0E1 “Loadcell calibration error” occurs. Try the
calibration again.
Caution: Operation commands are not accepted normally if the CLBR signal is set to ON.
Note 1 The time zone indicates the calibration signal check time (20ms). If CLBR is turned OFF
within the period, the calibration signal is ignored to cancel the calibration.
Note 2 The calibration time depends on Parameter No.119 “Loadcell calibration time” (factory
setting: 10ms). However, if it is set to the automatic calibration at startup, the time should
be fixed to 10ms no matter what the parameter setting is.
If CLBR is turned OFF during the period before CEND is turned ON, alarm 0E1 “Loadcell
calibration error” occurs.
[Reference] Loadcell is a delicate measurement tool. To maintain its accuracy, it is suggested
to have a calibration at regular intervals (conducted by the supplier).
Please contact us for the details related to the calibration such as the calibration
frequency.
