3.2.2 CAN interface
Drives approved by Lenze can be connected to the CAN2 interface.
The CAN2 interface is connected to the 9−pole D−Sub connector with
standard connector allocation via the CAN driver (electrically isolated). The
isolation voltage to the computer is 500 V.
The CAN2 bus must be terminated in the connector with a 120 Ohm resistor.
A Can high−speed interface is implemetned in accordance with the ISO/DIS
11898 standard. The ETCHx is implemented as CAN Master.

Devices can be connected to the CAN1 bus which are triggered via the PLC
and support the CANopen profile DS 301. The bus lines can be picked up
directly at the bus connection if required.
The CAN1 interface is connected to the ME bus via CAN driver with electrical
connection to the PC. If the ETCHx is used at the CAN bus start or end, the bus
must be terminated with a terminating resistor of 120 Ohm (DIP switch on
the power supply unit ETCHN003 or the bus termination module ETCHT000).
To connect a block of interconnected modules to other CAN statiions the
CAN bus signals are directed to the upper terminals in the power supply
module ETCHN003 and the bus terminator module ETCHT000.
