Modbus RTU for MCD1 Communication manua

Communication manual1. Parameters1.1 GeneralThe main starting / stopping parameters of MCD1 soft starter can be set by the panel potentiometer. Other parameters have been set up at factory commissioning, users do not need to set them. Other parameters can be adjusted by RS485 communication.1.1.1 Main parameterParameter Full Load Amps FLA MODBUS address 40002 Setting range 1-100 Default Rated current of softstarter According to lectotype. Factory setting1.1.2 Protection parameterParameter Over current protection value Parameter Over current trip delay time MODBUS address 40005 Setting range 500-850% Default 500% Factory setting Default 0.1Sec. Factory settingMODBUS address 40006Setting range 0.1~1.0Sec.Caution MCD1 has two different levels of over current breaking protection. 1. When the current is greater than 850% soft starter rated current (FLC), the soft starter will trip immediately. Fault relay (K2) tripped. 2. When the output current is greater than the over current protection set value (the motor rated current FLA 200%-850%) the soft starter is delayed for a period of time (“over current action delay time” specified time) then trip, the fault relay (K2) tripped.2Classified as BusinessCommunication manual Parameter Over load protection MODBUS address 40007 Setting range 100~200% Default 110% Factory setting Default 0-grade10A Factory settingParameter Overload protection gradeMODBUS address 40008Setting range 0-grade10A 1-grade 10 2-grade 20 3-grade 30Overload curve Caution Thermal protection of MCD1. It is recommended that users set overload protection to (level 10A) , When the setting less than “overload protection value”, the soft starter detect overload protectionClassified as Business3Communication manual Parameter Phase sequence protection MODBUS address 40015 Setting range 0-OFF 1-ON Default 1 - ONThe parameter setting protection functions not introduced above. Caution More protections of SLR: 1) Overtemp protection. When the heatsink temperature is above 85 degrees, the soft start trip . 2) When the soft starter input terminal/output terminal missing phase, the soft start trip. 3) When The phase sequence of the soft starter line is abnormal, the soft starter is not allowed to start. 4) When the power module is short circuited, soft start tripped. 5) when the three-phase current of the soft starter is unbalanced (three-phase current difference 20%FLA), soft starter trip.1.1.3 Start / stop parametersParameter Initial voltage MODBUS address 40010 Setting range 30-70% Default According to customer. Panel potentiometer setting.Caution The Initial voltage is set through the panel, and the setting value can only be read through communication mode, but it can’t be changed.Parameter Starting timeMODBUS address 40011Setting range 1-30 Sec.Default According to customer. Panel potentiometer setting.Caution The starting time is set through the panel, and the setting value can only be read through communication mode, but it can’t be changed.4Classified as BusinessCommunication manual Parameter Stop time MODBUS address 40012 Setting range 0-30 Sec. Default According to customer. Panel potentiometer settingCaution The stop time is set through the panel, and the setting value can only be read through communication mode, but it can’t be changed.Voltage slope starting mode UN: Rated voltage Uini: Initial voltage T1: Acceleration time At a predetermined acceleration time (T1), the output voltage of the soft starter rises from the voltage to the full voltage (rated voltage Un).Caution The motor can’t start(Locked-Rotor) if the voltage is too low. It is suggested that set initial voltage from high to low or use the Recommended setting.1.1.4 Relay parametersParameter Bypass relay type MODBUS address 40014 Setting range 0-Electric self holding relay 1-Magnet self holding relay Default Depending on the specific model Factory settingCaution The type of bypass relay is not allowed to be changed!Classified as Business5Communication manual1.1.5 Communication parametersParameter Slave machines address MODBUS address 40017 Setting range 1~127 Default 1 Factory setting Default 3-9600BPS Factory settingParameter Baud rateMODBUS address 40018Setting range 0-1200BPS 1-2400BPS 2-4800BPS 3-9600BPS 4-19200BPS Setting range 0-ECC 1-ODD 2-NONEParameter Parity checkMODBUS address 40019Default 0-ECCCaution After setting up the communication parameters must restart the MCD1 soft starter. Incorrect settings cause communicate fault, it could cause cannot setting again. MCD1 can not restore the default parameter, so please be careful when setting communication parameters.6Classified as BusinessCommunication manual1.2 Parameters tableParameter Full Load Amps (FLA) Reserve Reserve Overcurrent protection value Overload protection MODBUS address 40002 40003 40004 40005 40007 Setting range 1…100A 0…1 65535…65535 500%-850% FLA 0.1 … 1SEC 100-200% FLA 0-grade10A 1-grade10 2-grade20 3-grade30 0...512 30 +int((512-n)/32)*3 0…512 (512-n)/16 0…512 (512-n)/16 0-potentiometer setting. 1-communcation setting. 500% FLA 0.1 Sec.
