Assignment of references from a network
Reference parameters
The Altivar 61 supports a number of reference parameters, which must be selected according to the functions used in the drive.
Example 1:
The drive is to be controlled by sending the speed reference to the PID regulator via CANopen. No application function is used.
The following must be assigned:
The drive is to be controlled by sending the speed reference to the PID regulator via CANopen. No application function is used.
The following must be assigned:
[Ref.1 channel]
(Fr1)
=
[CANopen]
(CAn)
The following must be sent: Speed reference
(LFRD)
Example 2:
The drive is to be controlled by sending the PID regulator reference via Modbus.
The following must be assigned:
The drive is to be controlled by sending the PID regulator reference via Modbus.
The following must be assigned:
[Ref.1 channel]
(Fr1)
=
[Modbus]
(Mdb)
The following must be sent: PID regulator reference
(PISP)
Example 3:
The drive is to be controlled by sending the PID regulator reference and the feedback via the Ethernet card.
The following must be assigned:
