MICROMASTER 430 7.5kW-250kW

Function
Enables up to three additional motors to be controlled based on PID control
The entire system is made up of a pump which is controlled by the inverter with up
to an additional 3 pumps which can be added to the system via contactors or motor
starters.The motor starter is controlled via the output relay in the inverter. Figure
4-3 shows a typical pump system.
This function can also be used accordingly for ventilators and ventilation shafts.
For additional settings please refer to parameter list P2370 and following.

MICROMASTER 430 – Technical Data

The Siemens Micromaster 430 series is a drive system that was designed to perform a set of specific requirements. There has been a demand for inverter solutions that can be flexibly in simply adapted to solve a broad variety of challenges This type of flexibility is the main characteristic of the Siemens Micromaster 430 series and one of the main reasons for the widespread use of these drives.

The Siemens Micromaster 430 is often used for specific use with pumps and fans in the industrial business. The inverters perform a wide variety of tasks in similar applications as well. Compared to the Micromaster 420 series, the Micromaster 430 series has greater power efficiency along with more input/outputs. It even has an efficient operator panel that has the option to switch between manual and automatic operation modes.

The Micromaster 430 has wide moto protection thanks to a special PTC/KTY84 input. They are also specialized to be an ideal partner to industrial pump & ventilator applications. As with the Micromaster 420 and Micromaster 440 series, the Micromaster 430 also has various communication interfaces to ensure usability with the most common network applications. The 430 series is specially suitable for pumps and fans.

Voltage and power ranges380-480 V, ± 10%, 3 AC, 7.5 to 250 kW (10 to 300 HP)
Types of controlFCC (Flux Current Control), multipoint characteristic (parameterizable V/f characteristic), V/f characteristic

Bypass Mode
Setting up an inverter bypass circuit

Function
Control of two locked contactors via relay outputs of MICROMASTER 430. This
circuit makes it possible to operate the motor via the inverter or directly via the
mains. The inverter is responsible for switching.
Switching is possible by the following means:
error message from the inverter
. digital input
. inverter frequency
