Page 19: Calibration Procedure
HIGH-SPEED ANALOG OUTPUT 4.3 Calibration procedure 4.3.1 Calibration of voltmeter If a voltmeter is deviated, it can be calibrated at 0V or full-scale voltage (10V) output of the terminals DA2 to DA5. (1) Calibration at 0V output Turning ON the X83 turns ON the Y83. In the initial status, 0V calibration is performed At least 20ms required at power OFF →... - Page 20 HIGH-SPEED ANALOG OUTPUT CAUTION • Keep the X83 signal ON for 20ms or longer. Otherwise, calibration may not be performed. • When the X83 signal is assigned, 0V calibration is not performed at power ON and at inverter reset. If power is turned OFF while the X83 is assigned, a 0V-calibrated value returns back to the logical value because the inverter does not save such calibrated values.
