All the drive functions are accessible via the network:
• Control
• Monitoring
• Adjustment
• Configuration
If the "Controller Inside" programmable card is installed on the drive, its variables (%MW, etc.) can be accessed via the integrated Modbus
ports or the Ethernet option card.
The speed/torque control and reference can come from different sources:
• The I/O terminals
• The communication network
• The "Controller Inside" programmable card
• The remote graphic display terminal
• The PowerSuite software workshop (for commissioning and maintenance)
The Altivar 61 drive's advanced functions can be used to manage switching of these control and reference sources according to the
application requirements.
The periodic communication variables can be selected via:
• The network configuration software (Sycon, etc.): CANopen, DeviceNet
• The Altivar 61 drive's communication scanner function: Profibus DP, Fipio, Modbus Plus
• The network's IO Scanner function: Ethernet TCP/IP
With the exception of DeviceNet, regardless of network type, the Altivar 61 can be controlled:
• In accordance with the Drivecom profile (CANopen CiA DSP 402)
• In accordance with the I/O profile, whereby control is as straightforward and flexible as control via the I/O terminals
The DeviceNet card supports the ODVA standard profile.
Communication is monitored according to criteria specific to each protocol. Regardless of protocol type, the reaction of the drive to a
communication fault can be configured:
• Drive fault involving: Freewheel stop, stop on ramp, fast stop or braked stop
• Stop without drive fault
• Maintain the last command received
• Fallback position at a predefined speed
• Ignore the fault
A command from the CANopen bus is handled with the same priority as an input from the drive terminals. This enables very good response
times to be achieved on the network port via the CANopen adapter.
