Fieldbus control through the embedded fieldbus interface (EFB)
Operation mode specific bits:
Modes of operation
The operation mode defines the behavior of the drive. The following CiA 402
operation modes are supported:
•
Profile velocity mode
•
Profile torque mode
•
Velocity mode
•
Cyclic synchronous velocity mode
•
Cyclic synchronous torque mode
The ACS380 CANopen implementation supports minimal implementation of the
operation modes. In this chapter scalings of the reference and actual values are
described for each operation mode. Operation-mode-specific objects are
defined in section
The mode of operation is automatically selected to be either velocity mode or
profile torque mode according to the control mode configured with parameter
(depending on the current control
location). The correct reference scaling must be selected with parameters
. When in Velocity mode, the drive can be
switched to Profile velocity mode or Cyclic synchronous velocity mode with the
object 6060h. When in Profile torque mode, the drive can be switched to Cyclic
synchronous torque mode with the object 6060h.
Velocity mode
Velocity mode is a basic mode to control the velocity of the drive with limits and
ramp functions. Target velocity is set with the object 6042h and velocity actual
value can be read from the object 6044h. Velocity values are scaled with the
dimension factor given in object 604Ch. By default the dimension factor is 1,
and the velocity values are given in rpm, e.g. 1 = 1 rpm.
Profile velocity mode
The profile velocity mode is used to control the velocity of the drive with no
special regard of the position. Target velocity is set with the object 60FFh and
the velocity actual value can be read from the object 606Ch. Velocity values are
given in increments per second. Increment resolution is defined by the object
608Fh. The default values in object 608Fh are 65536 increments per 1
revolution. This means that 1 rpm equals 1 [rpm] * 65536 [inc/s] / 60 [s/min] =
1092 inc/s.
