iSFT Intelligent Motor Starting Controller

The iSFT intelligent motor starting controller has been designed for demanding motor starting applications with the following features:


 
iSFT Controller Front Panel Detail Typical applications for the iSFT are:
  • Control of high inertia loads such as large fans and crushers,
  • Control of high static friction loads such as material transport mechanisms, and
  • High availability, fully protected loads such as in waterwork pumping stations.

The iSFT controls the voltage supply to the load under the following fully programmable and user-configurable conditions:


The controller features a versatile two tier error handling system. Warning/alarm and fault conditions are configured individually for each controller variable and external event. Each warning/alarm and fault flag can be individually enabled and configurable in terms of trigger limit and delay.
 

The iSFT interfaces to local and remote devices via its individually configurable input, output, relay and network ports in an extremely flexible and versatile manner:

The interface to the thyristor assembly is efficient and effective:
  • The six thyristor gates are driven individually and directly (no other device is needed), and
  • The four configurable bit inputs interface to the assembly's fault, event and other signals.


(Thyristor assemblies are offered separately on a custom, per order basis).

Typical thyristor assembly (offered separately)

The front operator panel consists of a large five digit LED display and four operator switches. It is protected to IP54 and is covered by a polyester membrane. The display is visible through a suitably transparent window and the switches are of the tactile type. The controller is designed to be fixed on the inside of an electrical cabinet door/panel with the operator panel facing outwards through a suitable opening.
 

All connections are made via removable terminal blocks at the controller top and bottom.
 

All iSFT parameters can be set or edited locally (via the front panel switches) and/or through the serial port (EIA-RS-232 and EIA-RS-485). The parameters can be set at any time while the controller is powered. In this way the controller operation can be determined dynamically (as in the case of fuzzy control).
 
 

Quamatic full screen iSFT Controller data The iSFT controller is automatically detected when in a Quamatic or similar network. In this case, all data, parameters, settings etc are available on-line in hard real time.
