From the results, the PID constants are automatically set in the “proportional band” (P), “integral time”(I), and “derivative time” (D) parameters.• This parameter is normally off. If you press the U key, the parameter isturned ON and AT is executed. AT cannot be executed when control isstopped or during ON/OFF control.Operation• When AT execution ends, the parameter setting automatically returns tooff.■ Related ParametersSeeProportional band, Integral time, Derivative time (adjustment level): Page 138PID ON/OFF (initial setting level): Page 149cmwtCommunications WritingCommunications must be supported.This parameter enables/disables writing of parameters to the E5CN from thehost (personal computer) using communications.FunctionON:Writing enabledOFF: Writing disabledSetting• Default: OFF■ Related ParametersSeeMB command logic switching (advanced function level): Page 169Communications Unit No., Communications baud rate, Communications datalength, Communications parity, Communications stop bits (communicationssetting level): Page 182131Section 5-4Adjustment Levelct1Heater Current 1 Value MonitorHeater burnout and HS alarms mustbe supported.Alarm 1 must be assigned.The “heater burnout detection”parameter must be set to ON.This parameter measures the heater current from the CT input used fordetecting heater burnout.This parameter measures and displays the heater current value.Function• Heater burnouts are not detected if the control output (heating) ON time is190 ms or less.Monitor range0.0 to 55.0MonitorUnitA• ffff is displayed when 55.0 A is exceeded.• If a heater burnout is detected, the HA indicator will light, and the relativesetting level will flash on the No.
