Calibration 5-3 Calibration Procedure For current measurement accuracy, use the procedure below to calibrate the SMC Dialog Plus controller to the connected motor. A clamp-on ammeter, which provides a true rms measurement and has a published accuracy of ±1% (Fluke model 33 or equal), is required to perform this procedure. Notes: (1) If you plan to use the Bulletin 825 converter module for current feedback to the SMC Dialog Plus controller, this calibration procedure is not necessary. (2) An unbalanced three-phase system may affect the accuracy of the calibration. (3) It is recommended that Parameter #36, Overload Class, is programmed to OFF during the calibration procedure. Additionally, the motor must be connected to its load in order that the motor draw as near to its full load current (FLC) rating as possible. This is necessary so that maximum accuracy is achieved for current measurements at overload trip levels. Description 1. Check all power and control wiring connections to the controller and motor. Apply a start command to the controller and check for motor rotation to full speed. Monitor the clamp-on ammeter and verify that the motor current is stable. Monitor the ammeter display for the next 2 seconds and record the average value. During this time period, the SMC Dialog Plus controller samples motor response data.

ATTENTION: After calibration is completed, program the desired overload class and save the setting to the controller's EEPROM. ATTENTION: This method of current measurement is not applicable to multi-motor installations or resistive heating loads. Utilization of the Bulletin 825 converter module is required for these applications if current measurement is required.
