Extension CANopen Card (MD38CAN2)
MD38CAN2 is designed to connect the drive to high-speed CANopen bus. CANopen is
an international eld bus standard. Equipments supporting this protocol can be connected
to the CANopen bus.
MD38CAN2 supports the following ve protocols:
1. The Node Guard protocol, with which master can read equipment status
2. The Heartbeat protocol, with which slave detects current state to master regularly
3. The SDO that supports accelerated transmission mechanism only and transmits one
function code (two bytes)
4. Three TPDOs and three RPDOs
