Operating Manual dryve D1, ST-, DC-, EC/BLDC-Motor Control System - V2.4
4.2.3 Communication Interfaces
X7 CANopen Port
The dryve D1 may be controlled with the CANopen communication protocol. For this purpose, the dryve D1 will be connected to
the bus and the master via the CANopen port. The standard pin assignment in accordance with CiA 301 is illustrated in the
table.

Transmission Speeds
Possible transmission speeds are dependent on the used cable lengths. The dryve D1 supports
up to 1 Mbit/s.

Termination Resistors
At each end of the bus cable, the CAN bus needs a termination resistor with 120 Ω between the CAN high channel and the CAN
low channel. These resistors are needed for defined difference-signal evaluation of the CAN low and CAN high channels.
X8 Ethernet/Modbus TCP Gateway Port
The assignment of the X8 Ethernet port corresponds to the standard assignment according to TIA-568A/B.
