3.4.1
FHPP
FHPP makes it possible to achieve a uniform control concept regardless of the field bus
used. The user therefore no longer be concerned with the specific characteristics of the
respective busses or controllers (PLC), but receives a preparameterized profile in order to
place his drive into operation in the shortest possible time and control it.
Among the operation types, FHPP distinguishes between record selection and direct
operation.
With record selection, the position records stored in the controller are used.
In direct operation,
the positioning mode,
speed control or
force control
can be employed.
These can be dynamically switched over in direct operation as needed.
Additional information can be found in the FHPP manual P.BE−CMM−FHPP−SW−EN.
3.4.2
CAN bus
Communication
The CAN bus is permanently integrated in the controller and can be parameterized and
activated/deactivated via the DIP switches on the front side. With the DIP switches, the
node address and baud rate can be set visibly from the outside. In addition, a termination
resistor can be connected and the CAN bus switched on or off. The controller supports
baud rates up to 1 Mbit/s.
If the communication protocol FHPP is used, the above-mentioned operating modes are
available.
Alternatively, if the CANopen protocol in accordance with DS301 with application profile
DSP402 is activated,
the positioning mode (CiA: profile position mode),
homing mode (CiA: homing mode),
interpolated position mode (CiA: interpolated position mode)
speed control (CiA: profile velocity mode) and
force mode (CiA: torque profile mode)
can be used.
Communication can take place optionally over SDOs (service data objects) and/or PDOs
(process data objects). Two PDOs are available for each sending direction
(transmit/receive).
Contour control with linear interpolation
With the "interpolated position mode", a contour control can be implemented in a multi-
axis application of the controller. For this, position setpoints are specified by a higher-
