Parameter setting & configuration
Cyclic synchronous position mode (IEC 61800-7)
146 L EDS94TA11010xxxx EN 1.2 - 03/2010
Internal variables of the motor control (oscilloscope signals)
The red numbers in brackets specified in the signal flow represent internal variables of
the motor control which can be recorded with the oscilloscope for diagnostic and
documentation purposes.
3.12.4 Setpoint selection
The position setpoint is selected via the 0x6071
object (target position). Use the 0x60B2
object (offset position) to additionally define an offset which is added to the position
setpoint.
The speed feedforward control value is selected via the 0x60FF
object (target velocity). Use
the 0x60B1
object (offset velocity) to additionally define an offset which is added to the
speed setpoint.
The torque feedforward control value is selected via the 0x6071
object (target torque). Use
the 0x60B2
object (torque offset) to additionally define an offset which is added to the
torque feedforward control value.
3.12.5 Setpoint interpolation
Similar to the "Interpolated position mode
", the resulting position setpoint is interpolated
in this operating mode as well, if the communication cycle time differs from the control
cycle time of the controller (1 ms).
For the determination of the required interpolation steps the 0x60C2
object
(interpolation time period) is used.
