SIEMENS Micromaster VFI 6SE9221-8CC40 5.0HP 230V AC

MICROMASTER offers standard open loop V/F Control and is ideal for simple applications such as pumps and fans.

Both ranges of drives benefit from the standard inclusion of a PID controller (PI for the MICROMASTER) for closed loop process control.

All the products make use of the same, simple to use, standard user interface consisting of seven push buttons and LED display.

User-friendly screwless terminals are used for the control connections.

An RS485 serial interface is standard, allowing up to 31 drives to be networked to a PLC or PC.

The drive may be enabled via the keypad, via digital inputs or over the standard RS485 serial interface.

The motor speed setpoint can be selected, using a digital setpoint, motorised potentiometer, fixed frequency, analogue input or via the serial link.

Mixed mode control is also available, allowing drive control and setpoint input to be from different sources.

A DC injection brake is incorporated, allowing DC to be output even when the motor is stationary.

The drives can be configured to start automatically following a mains break or after a fault.

The parameter sets are fully compatible between the different product types, reducing the learning time.

All drives are certified in accordance with VDE, UL and Canadian UL, and are manufactured to ISO9001.

All drives conform to the requirements of the EC low voltage directive 73/23/EEC and have been awarded the CE mark.

All drives are guaranteed Y2K (year 2000) compliant.
