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)
Applications
AS-Interface motor starters and IP65/67 load feeders
AS-Interface motor starters IP67 (24 V DC)
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
the Quick stop function receives a "High" signal, the correspond-
ing output (e.g. Quick stop input 1
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 for single direct on-line
stop function receives a "High" signal, the corresponding output
(e.g. Quick stop input 1
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.
