E 1145 - JOAP

Page 10 of 16 Motor profile for drive must be selected at the dip-switch before 0-10V add-on print is mounted in drive. When print is mounted there will be access to the clamps shown on the drawing on the right. Note; The ModBus connection in the bottom is only a ModBus- to-datalogger (PC) Connection and is only to be used for development or service purposes. 1 = Run 2 = Gnd 3 = 0-10V in 4 = 0-10V in option 4 3 2 1 NPN Alarm 48V 0,5A ModBus Connection The Power - Amp. (How?, Where?, What?) POWER Amp. The 1145 has integrated APFC making the current in the power input 99,8 % sine waved. Grey = All integrated in 1145 Amplifiers Capacitor Power module Load DC Loader. In 1145 the standard 105°C capacitor is used. This in conjunction with a more smoothen power consumption ensures a long lifetime of the drive - up to 12- 15 years. The amplifier power module is the module making the 3 phases for the load. The power and heat emission is a very complex composition of Switch-frequency, voltage in the middle circuit and current. The best result is obtained by following our guidelines regarding cooling and load. For total load it is always A per phase which is valid. To select the right inverter you need to know: The motor current, as it defines the capability of the output stage of the drive. The total electric power consumption expressed in watts, as it defines the capability of the power entry stage and APFC. Note: For BLDC motors the 1145 uses a high speed calculation to ensure optimal operation of the motor. It is therefore essential to use current A and total power for dimensioning. Also it is of most importance to take in to consideration that voltage and frequence vary hence A is the important limit. Run GND 0-10V Mode 0-10V 4 3 2 1 APFC Active Power Factor Correction which is integrated in E1145 makes the absorbed power almost 100% sinus waved. With this circuit the drives works with main fuse 16A for 3000W and the calculation of the total power is without harmonic losses. Calculate 1 to 1-1. In grid This gives a high net current with significantly high amounts of harmonic currents = Need for heavy dimensioned cables and fuses. Cannot comply to standards for 1 phased products under 16A. Drive without APFC means that a rectifier charges directly into a middle circuit capacitor. APFC Power input Rectifier
