In this menu the alarm can be enabledand an action to be performed can be chosen. The followingoptions are available:OffSerial communication contact broken alarm is disabled.WarningAlarm message F15 is shown in the display and relay K3 isactivated (for default configuration of the relays). However,the motor is not stopped and operation continues. Thealarm message will disappear and the relay will be reset whenthe fault disappears. The alarm may also be reset manuallyfrom the control panel.CoastAlarm message F15 is shown in the display and relay K3 isactivated (for default configuration of the relays). The motorvoltage is automatically switched off. The motor freewheelsuntil it stops.StopAlarm message F15 is shown in the display and relay K3 isactivated (for default configuration of the relays). The motoris stopped according to the stop settings in menus [320] to[325].Alarm BrakeAlarm message F15 is shown in the display and relay K3 isactivated (for default configuration of the relays). The brakefunction is activated according to the braking method chosenin menu [323] and the motor is stopped according tothe alarm brake settings in menus [326] to [327] (brakingstrength and braking time).A serial communication broken alarm is automatically resetwhen a new start signal is given. The start signal can begiven via control panel, remotely or via serial communicationdepending on the control source chosen in menu 200.Regardless of the chosen control source, it is always possibleto initiate a reset via control panel..NOTE: A reset via control panel will never start themotor.2 7 3oFFSettingSerial comm. contact broken(alarm code F15)Default: 3Range: oFF, 1, 2, 3, 4oFFSerial comm. contact broken disabled1 Warning2 Coast3 Stop4 Alarm Brake8.7 Operation settingsOperation settings include parameters for configuration ofstarting and stopping, some of these can be pre-configuredfor pump applications. Furthermore, some special settingsfor stop behaviour at alarm, parameters for slow speed andJOG and additional settings such as bypass operation, powerfactor control and control of the internal fan are included inthis section.[300] Preset pump control parameters[310]-[317] Start[320]-[327] Stop including stop at alarm[330]-[335] Slow speed/JOG[340]-[342] Additional settingsThe MSF Softstarter controls all three phases supplied to themotor. In contrast to a simple softstarter controlling onlyone or two phases, the three-phase control enables differentstarting methods, voltage, current and torque control. A currentlimit can also be used in combination with either voltageor torque control.Emotron AB 01-4135-01r2 Functional description 55
With voltage control the output voltage to the motor is linearlyincreased to full line voltage during the set start time.The softstarter gives a smooth start but does not get anyfeedback on current or torque. The typical settings to optimizea voltage controlled start are the initial voltage and thestart time.With current control the output voltage to the motor is regulatedso the set current limit is not exceeded during thestart. With this starting method the starter does not get anyfeedback on the motor torque either. However, current controlcan be combined with both voltage and torque control.The typical settings to optimize a current controlled start arethe current limit and the maximum starting time.Torque control is the most sophisticated way of startingmotors. The softstarter continually monitors the motortorque and controls the output voltage to the motor so thetorque follows the set ramp. Both linear- and square torqueramps can be chosen according to the application requirments.In this way constant acceleration can be accomplishedduring start which is very important in manyapplications. Torque control can also be used for stoppingwith constant deceleration. For pumps constant decelerationis important for avoiding water hammer.8.7.1 Preset pump control [300]With this multi-setting parameter the MSF 2.0 softstartercan easily be configured for pump applications. The followingparameters are set if preset pump control parameters arechosen.[310] Start method is set to square torque control (2)[311] Initial torque at start is set to 10%[312] End torque at start is set to 125%[315] Start time is set to 10 seconds[314] and [316] Current limit at start and torque boost aredeactivated.[320] Stop method is set to square torque control (2)[321] End torque at stop is set to 10%[325] Stop time is set to 15 seconds.These settings will lead to a smooth start with linear accelerationand a linear stop without water hammer for mostpump applications. However, if the pre-set parameters needto be adapted for a specific application, the values in the relevantmenus can be adapted.The following figure shows typical current characteristics atstart and speed curve at stop.Current (A)SpeedFig. 36 Pump control. Current at start and speed at stop.When the pre-setting of the parameters for pump controlhas been executed successfully, “SEt” is shown in the displayfor two seconds. After that “no” will be shown again.NOTE: Pre-setting of parameters for pump control is notallowed when the softstarter is running. In this case“SEt” is not shown.3 0 0Default:Range:noYESn oPreset pump control parametersnono, YESNo actionPreset parameters for pump controlTimeTimeMulti Setting56 Functional description Emotron AB 01-4135-01r2
