5. Drive profile
Using CiA 402 Drive profile, form CANopen network, the drive can be controlled. When using the drive
profile command, please set the command mode selection to CANopen (cmod=3), Frequency setting
mode selection 1 to CANopen (fmod=6) and
Number of motor poles for communication (f856)
parameters.
Warning
Mandatory
action
If use and set RS485 communication command parameter, the infinite state machine of
drive profile can not work expected behavior and may be damage the drive or cause
danger. So when use RS485 command parameter, do not access the drive object
profile.
5.1. Velocity mode object
Below figure describes the object relation.
Function CANopen Protocol
Velocity limit function Limit the target velocity command (6042) regarding to min/max (6046).
And set to inverter frequency command. If target velocity command is over or
less than 6046 value, set limit value to the inverter.
Ramp Function Ramp function is provided by the inverter.
CANopen protocol read the demand value and set to 6043.
Velocity Control function CANopen protocol read demand value and set to 6044.
