Interface microstarter – switching, pro-

tecting and communicating in the mo-

tor terminal box

We have now reached another milestone

in distributed drive technology in the form

of the new AS-Interface microstarter.

You can now completely replace the mo-

tor terminal box by an AS-Interface mi-

crostarter up to 4 kW.

The motor can be mounted in any posi-

tion. Thanks to its compact design, the

AS-Interface Microstarter can be used

wherever space is especially tight. Elec-

tronic overload protection is especially

cool: The motor is continually monitored

using thermistor evaluation and when a

fault develops, it is automatically tripped.

However, the AS-Interface motor starter

can do a lot more. Signals, which are

available close to the motor (e.g. Bero

proximity switches) can be read-in using

the two digital inputs integrated in the

starter and can be transferred to the AS-

Interface master. This means that addi-

tional modules can be eliminated. Not

only this, the AS-Interface motor starter

can be integrated into Category 1 safety

concepts (in compliance with EN 954-1).

Integrated LEDs make local diagnostics

fast and precise. A fault signal is also im-

mediately sent to the AS-Interface mas-

ter – for a truly integrated drive solution.

K60R: The IP68 module for the

AS-Interface

The K60R module, with round cable

connection and degree of protection

IP68, is now available – and it supple-

ments the K45/K60 series of compact

modules with degree of protection

IP65/67. The new design can be operat-

ed in environments which have high

permanent levels of moisture. This re-

sults in many practical applications.

• Use in especially moist ambient con-

ditions, for example, in beverage filling

systems, on machine tools and in the

food and beverage industry.

• The K60R module, with degree of pro-

tection IP68, can now be cleaned under

high pressures and it is even possible to

use liquid cleaning agents capable of

film creep.

• The module is connected to the AS-

Interface bus and the auxiliary voltage

using a round cable which is connected

to the module using an M12 connector.

Microstarter

The direct-on-line and reversing starter

with communication capability and de-

gree of protection IP65 has a power of

up to 4 kW and can either be integrated

directly into the motor terminal box or

replace the terminal box completely. On

AS-Interface, the microstarter acts as a

standard slave with 4 inputs and out
