2.5.3 Configuring a Sercos drive.
SERCOSDATA
Sercos drive data.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for a Sercos drive.
This parameter shows the table to define the communication with the Sercos drive.
DRIVEID
Sercos drive address.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for a Sercos drive.
Possible values: From 1 to 32.
Default value: 1.
Associated variable: (V.)[ch].MPA.DRIVEID.xn
Parameter included in the SERCOSDATA table.
This parameter indicates the position (node) occupied by the drive in the Sercos connection.
OPMODEP
Drive's main operating mode.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for a Sercos drive.
Possible values: Position / Speed.
Default value: Position.
Associated variable: (V.)[ch].MPA.OPMODEP.xn
Parameter included in the SERCOSDATA table.
This parameter indicates the operating mode of the Sercos drive; velocity command or
position command. Refer to the drive manual for further detail.
We recommend to set the axes (except tandem axes) to operate in position-Sercos mode
and the spindles in velocity-Sercos mode. However, tandem axes must necessarily work in
velocity-Sercos mode. All the axes that will be interpolated with the tandem axis must also
operate in velocity-Sercos mode.
Operating mode of the drive in velocity-Sercos.
• The velocity command is sent out to the drive in ten-thousandths rpm of the motor When
needing to use the SANALOG from the PLC, its value will also be given in ten-
thousandths rpm of the motor.
• The CNC receives the drive's feedback as absolute coordinate in ten-thousandths of a
millimeter or thousandths of a degree (same as in Sercos position mode).
• The CNC controls the home search. The home search is carried out without stopping
the spindle if it was turning. If it is turning in M03 or M04 and M19 is programmed, the
spindle decelerates down to REFFEED1 and starts searching home.
• The following error and the backlash compensation are calculated at the CNC.
• The CNC applies feed-forward and AC-forward.
• When the spindle is turning in open loop, the coordinate is simulated.
Operating mode of the drive in position-Sercos.
• The command is sent out to the drive in absolute coordinates, in ten-thousandths of a
millimeter (linear axes) or thousandths of a degree (rotary axes). When needing to use
SERCOSDATA
DRIVEID Sercos drive address.
OPMODEP Main operating mode of the Sercos drive.
FBACKSRC Type of feedback.
FBACKDIFF Maximum difference between feedbacks.
ULTRAIPO Parameter not being used at this time.
FBACKTIME Time constant for combined feedback.
