■ Overview
Connection of an actuator roller with integrated DC motor to an AS-Interface 24 V DC 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 starters (without brake and reversible
quick-stop function)• Double direct-on-line starters (with brake and reversible
quick-stop function)• Reversing starters (with brake and reversible quick-stop
function)
DC motors are connected to the module using M12 plug-in con-nections. The sensors and the module electronics can be sup-plied from the yellow AS-Interface cable. An auxiliary voltage (24 V DC) 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 using a switch integrated into the module. The quick-stop function al-lows a connected motor to be disconnected immediately using an applied sensor signal (High). The switch for the quick-stop function is located alongside the input sockets and is protected by an M12 sealing cap.
Brake
The double direct-on-line starter and the single reversing starter versions feature an integrated permanently set brake function, i. e. as soon as the output signal is set to "0", the motor is braked.
Start-up using 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 sealing cap.
Note: Concerning double and reversing 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 device (the motor is braked). The manual key function (Key 1/2) for local operation is only permitted to be used during "CPU Stop" in the higher-level PLC.
Note:Concerning 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 device (the motor runs down without being braked) The ma-nual key function (Key 1) for local operation is only permitted to be used during "CPU Stop" in the higher-level PLC.
