AS-Interface motor starters IP67 (24 V DC)

■Overview

Connection of a drive roller with integrated DC motor to an AS-Interface DC 24 V motor starter

With the K60 AS-Interface 24 V DC motor starters for the low-end performance range up to 70 W, it is now possible to connect

24 V DC motors and the associated sensors directly to the AS- Interface quickly and easily.

Three different versions are available:

•Single direct on-line starter (without brake and reversible quick-stop function)

•Double direct on-line starter (with brake and reversible quick- stop function)

•Reversing starter (with brake and reversible quick-stop func- tion)

DC motors are connected to the module via M12 plug-in con- nectors. The sensors and the module electronics can be sup- plied from the yellow AS-Interface cable. An auxiliary voltage (DC 24 V) is only required for supplying the outputs, which can be provided via the black AS-Interface cable.

Quick stop function

All AS-Interface 24 V DC motor starters feature a quick-stop function which can be switched on and off as required via a switch integrated into the module. The quick-stop function al- lows a connected motor to be shut down immediately via an ap- plied sensor signal (high). The switch for the quick-stop function is located alongside the input sockets and is protected by an M12 covering cap.

Brake

The double direct starter and reversing starter versions feature an integrated permanently set brake function. As soon as the output signal is set to "0", the motor is braked.

Start-up via integrated buttons

Buttons integrated into the module (below the output sockets) can be used to set the motor used. The buttons are protected by an M12 covering cap.

Note concerning double and reversing starters: If an input with the Quick stop function receives a "High" signal, the correspond- ing output (e.g. Quick stop input 1 ￿output 1) is switched off

within the device (the motor is braked). The manual key function 6 (Key 1/2) for local operation is only permitted to be used during

"CPU Stop" in the higher-level PLC.

Note for single direct on-line starters: If an input with the Quick stop function receives a "High" signal, the corresponding output (e.g. Quick stop input 1 ￿output 1) is switched off within the de- vice (the motor coasts down without braking). The manual key function (Key 1) for local operation is only permitted to be used during "CPU Stop" in the higher-level PLC.
