Emotron FDU 2.0 AC drive

Bottling machine with 3 different productsUse 3 parameter sets for 3 different Jog reference speedswhen the machine needs to be set up. The 4th parameter setcan be used for “normal” remote control when the machineis running at full production.Manual - automatic controlIf in an application something is filled up manually and thenthe level is automatically controlled using PID regulation,this is solved using one parameter set for the manual controland one for the automatic control.7.1.1 One motor and one parametersetThis is the most common application for pumps and fans.Once default motor M1 and parameter set A have beenselected:1. Enter the settings for motor data.2. Enter the settings for other parameters e.g. inputs andoutputs7.1.2 One motor and two parametersetsThis application is useful if you for example have a machinerunning at two different speeds for different products.Once default motor M1 is selected:1. Select parameter set A in menu [241].2. Enter motor data in menu [220].3. Enter the settings for other parameters e.g. inputs andoutputs.4. If there are only minor differences between the settingsin the parameter sets, you can copy parameter set A toparameter set B, menu [242].5. Enter the settings for parameters e.g. inputs and outputs.Note: Do not change motor data in parameter set B.7.1.3 Two motors and two parametersetsThis is useful if you have a machine with two motors thatcan not run at the same time, such as a cable windingmachine that lifts up the reel with one motor and then turnsthe wheel with the other motor.One motor must stop before changing to an other motor.1. Select parameter set A in menu [241].2. Select motor M1 in menu [212].3. Enter motor data and settings for other parameters e.g.inputs and outputs.4. Select parameter set B in menu [241].5. Select M2 in menu [212].6. Enter motor data and settings for other parameters e.g.inputs and outputs.7.1.4 Autoreset at tripFor several non-critical application-related failureconditions, it is possible to automatically generate a resetcommand to overcome the fault condition. The selectioncan be made in menu [250]. In this menu the maximumnumber of automatically generated restarts allowed can beset, see menu [251], after this the AC drive will stay in faultcondition because external assistance is required.ExampleThe motor is protected by an internal protection for thermaloverload. When this protection is activated, the AC driveshould wait until the motor is cooled down enough beforeresuming normal operation. When this problem occursthree times in a short period of time, external assistance isrequired.The following settings should be applied:• Insert maximum number of restarts; set menu [251] to3.• Activate Motor I 2 t to be automatically reset; set menu[25A] to 300 s.• Set relay 1, menu [551] to AutoRst Trip; a signal will beavailable when the maximum number of restarts isreached and the AC drive stays in fault condition.• The reset input must be constantly activated.7.1.5 Reference priorityThe active speed reference signal can be programmed fromseveral sources and functions.
