Communication manual 1. Parameters 1.1 General The main starting / stopping parameters of MCD1 soft starter can be set by the panel potentiometer. Other parame- ters 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 parameter 1.1.2 Protection parameter 2 Classified as Business Parameter MODBUS address Setting range Default Full Load Amps FLA 40002 1-100 Rated current of softstarter According to lectotype.

Factory setting Parameter MODBUS address Setting range Default Over current protection value 40005 500-850% 500% Factory setting Parameter MODBUS address Setting range Default Over current trip delay time 40006 0.1~1.0Sec. 0.1Sec. Factory setting 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.

It is recommended that users set overload protection to (level 10A) , When the setting less than “overload protection value”, the soft starter detect overload protection

Communication manual The parameter setting protection functions not introduced above. 1.1.3 Start / stop parameters 4 Classified as Business Parameter MODBUS address Setting range Default Phase sequence protec- tion 40015 0-OFF 1-ON 1 - ON 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. Parameter MODBUS address Setting range Default Initial voltage 40010 30-70% According to customer. Panel potentiometer setting. Caution The Initial voltage is set through the panel, and the setting value can only be read through com- munication mode, but it can’t be changed. Parameter MODBUS address Setting range Default Starting time 40011 1-30 Sec. According to customer. Panel potentiometer setting. Caution The starting time is set through the panel, and the setting value can only be read through com- munication mode, but it can’t be changed.
