6SE9212-0DA40 - Inverter - SIEMENS

The MICROMASTERS are a range of frequency variators which allow you to control the speed of three-phase asynchronous motors. They are available in different variants ranging from the compact MICROMASTER for 120 W single-phase input to the MICROMASTER for 7.5 kW three-phase input. The drives are controlled by microprocessor and incorporate cutting-edge IGBT technology which guarantees reliability and flexibility. A special pulse width modulation process with adjustable ultrasonic pulse frequency guarantees extremely quiet motor operation. Complete protection of the drive and motor is provided by extensive protection functions.

Features :

• Simple to install, program and commission.

• Closed cycle control using a proportional and integral (PI) regulator circuit function.

• High take-off torque with automatic boost torque at start-up.

• Possibility of remote control via RS485 serial port using the USS protocol which offers the possibility of controlling up to 31 drives.

• A wide variety of parameters allow the configuration of the drives to be adapted to virtually any application case.

• Control panel with membrane buttons for ease of use.

• Saves settings in built-in non-volatile memory.

• Default settings are pre-programmed for European and American requirements.

• Five modes for controlling the output frequency (and therefore the motor speed):

(1) Frequency reference via the numeric keypad.

(2) High resolution analog setpoint (voltage input).

(3) External potentiometer to control motor speed.

(4) Fixed frequencies via binary inputs (TOR).

(5) Serial interface. (US protocol, PROFIBUS, CANbus)

• Integrated direct current injection braking with COMPOUND BRAKING.

• Integral RFI filter on single-phase current input drives (MM12 - MM300 and three-phase network drives MM220/3F to MM750/3F).

• Acceleration/deceleration time with programmable rounding.

• Fully programmable single relay output.

• External connector for multilingual clear text display (optional) or PROFIBUS module (optional).

• Automatic recognition of 2, 4, 6 or 8 pole motors by software.

• Integral software-controlled cooling fan.

• Fast Current Limit or fast current limitation (FCL) for reliable operation without interruption.

• Compact design and ability to mount drives side by side ensures a small footprint.
