11.1.4.1
External power supply
The external power supply can be fed through a 24V power pack or via the drive (e.g. MultiAx from
Control Techniques). See also Wiring Example with MultiAx.
Serial SLM interface
An SLM
interface always connects 3 stations:
- Motion contoller (XCN with XP-SLM)
- Converter (e.g. MultiAx from Control Techniques)
11.1.4.2
- Motor (e.g. Unimotor from Control Techniques)
XCN
(Position control)
Servo actuator
e.g. MultiAx
(current controller)
Motor
e.g. Unimotor
(SinCos-Encoder)
Data bus - SLM protocol
Hardware enable
Encoder inputs
Two handwheels can be connected optionally to the encoder inputs.
(The inputs are currently only available as hardware, a software interface is in preparation.)
Interrupt inputs
Tracers can be connected to the interrupt inputs.
There are 2 interrupt inputs on the card.
(The software currently only processes the interrupt input of connector X15.)
Note the following
$ functions and shared RAM variables for measuring functions:
$ functions
$53
Abort motion with following error compensation through interrupt signal
$54
Delete remaining distance through interrupt signal
