4.4 USB Connector

For serial communication the PD57/60/86-x-1260 oﬀers selection between RS485, CAN and USB interfaces.

The USB interface via on-board micro-USB connector (type B) is available for conﬁguration and service

of the board, mainly (e.g. parameter settings, ﬁrmware updates). The USB device interface supports

full speed (12Mbit/s) communication and supports bus powered and self-powered operation. During

bus-powered operation the low voltage logic part of the board will be powered, only. This includes the

microcontroller and the non-volatile memory and therefore allows parameter settings and ﬁrmware

updates of the board using a standard USB cable, only. Of course, for any motor movement main supply

via supply input connector is required.

NOTICE

Due to hardware ressource sharing USB and CAN communication interfaces are

not available at the same time. As soon as USB is physically attached to a host or

hub the CAN interface will be switched oﬀ.

4.5 I/O Connector

The PD57/60/86-x-1260 oﬀers several inputs (two of them optically isolated) and one digital (open-drain)

output. The inputs include support for stop switches (left and right), home switch, step/direction, incre-

mental A/B channel encoder and analog (0. . . +10V) input. All this functionality is available via one 8pin JST

PH series I/O connector.
