Market number (order): Siemens converter 6SE6440-2UD17-5AA1 MICROMASTER 440 - Description field in the drive, there are some things that are difficult to control. Siemens until after the advent of powerful drive, the situation can change. MICROMASTER 440 is designed for the need for more extensive than usual functionality and higher dynamic response of the application and design. These advanced vector control system ensures consistent high driving performance, even when sudden load changes. Due to the rapid response inputs and positioning deceleration ramp, therefore, even in the case without using the encoder and to be moved to a target position. The drive comes with an integrated brake chopper, even during braking and short deceleration ramp can to highlight the precision work. All of these can be realized within up 250 kW (350 HP) power range 0.12 kW (0.16 HP). About Siemens Drive "three guarantees" range 440: user manual for correct operation by product, due to manufacturing quality problems led to the whole or important parts can not be used after the technician confirmed by the company's maintenance, the "three guarantees" service. 1, refunding provisions: when the user presses the proper use of the product manual, from the date the product within 7 days from the date of sale, the occurrence of performance problems (refer to the product to meet the safety requirements, there is a threat to personal and property safety hazard or does not have to be available performance, etc.), customers can choose to return, replacement or repair, when to return, according to the sales price one-time payment. 2, shifting states: When the user presses the proper use of the product manual, from the date the product within 30 days of sale, the occurrence of performance problems (refer to the product to meet the safety requirements, there is a threat to personal and property safety hazard or does not have to be available performance, etc.), customers can choose a replacement or repair, when a replacement, exchange the same model with the customer specifications. 3, repair provisions: when the user presses the proper use of the product manual, from the date of sale within a year, the occurrence of performance problems (refer to the product to meet the safety requirements, there is a threat to personal and property safety hazard or does not have to be available performance, etc.), customers can choose a free repair service, repair, free of charge to the customer repaired or replacement parts. Siemens converter 6SE6440-2UC12-5AA1 Overview: Siemens converter MicroMaster440 is versatile standard drive a whole new generation can be widely applied.

Siemens converter 440 protection functions: 1, overload of 200% of rated load current, duration 3 seconds and 150% of rated load current, duration 60 seconds; 2, over-voltage, under-voltage protection; 3, inverter, motor overheating protection; 4, ground fault protection, short circuit protection; 5, latch motor protection to prevent stall protection; 6, using PIN numbers parameterized chain. As a business, a buyer, it is necessary to purchase should automation products MM4 inverter selection in need pay attention to those things, only in understanding MM4 inverter selection of eight principles for businesses to buy better MM4 inverter. First, the actual motor current value as selected according to the inverter. In selecting MM4 inverter should take full account of the higher harmonics of the inverter output is relatively high power factor and efficiency of the higher harmonics of the motor will deteriorate. So when choosing a motor and inverter, should take into account this situation, proper left margin, in order to prevent excessive temperature rise, affecting the life of the motor. Second, select the drive according to the load characteristics. If the load is constant torque load required to choose siemensMM4 drives, if the load for the fan and pump loads need to select the MM430. Third, the need to drive long cable runs, should take measures to suppress the influence of long cable coupling capacitance to ground to avoid the inverter output is not enough. Fourth, for some high ambient temperatures, high switching frequency (It should be noted especially in building automation and other applications for higher noise limit places to use), high altitude, etc. At this point will cause derating of the inverter, the inverter should be Select a file to enlarge. If the power supply is self-powered drive, plus the best line reactors. Fifth, when the use of inverter-driven gear motor, gear shift some of the scope of application was smooth method constraints. When the oil is smooth and smooth, there is no constraint in the low speed range; in the extra speed over the speed beyond the range of possible risk of the occurrence of light lubricating oil. Thus, do not exceed the maximum allowable speed value. Six, when the inverter drives wound rotor induction motor, mostly using existing motors. Motor winding comparison with the usual squirrel cage motor, motor winding impedance winding small. Therefore, prone to over-current trip due to the ripple current caused by the appearance, it should be slightly larger than the usual selection of drive capacity. Typically used for flywheel torque motor winding GD2 more occasions, in the set deceleration time should be more focus. Seven, when the inverter drives synchronous motor, compared with the commercial power supply, the output capacity will decrease by 10% to 20%, a series of output current of the inverter is greater than the product of the current and additional synchronous motor synchronous pulling into the current per-unit values. 8, on the lower compressor, vibration and other large load torque is shaken and a hydraulic pump, which are the peak load conditions, if the additional current or power value in accordance with the selection of the drive motor, then the peak current may occur due to overcurrent Maintenance initiatives appearance. Thus, you should know that the power frequency operating conditions, the selection of the maximum current greater than its additional output current drive.
