Start
(FHPP control byte)
CPOS.B1 = positive edge: Start
(CDIR.B0 = nominal position absolute/relative)
Feedback
(FHPP status byte)
SPOS.B2 = 0: Motion complete
SPOS.B1 = positive edge: Acknowledge start
SPOS.B4 = 1: Drive is moving
Requirement
Device control by PLC/Fieldbus
Controller must be in status “Operation enabled”
1)
The master transmits a percentage value in the output data, which is multiplied by the maximum
permissible speed in order to obtain the final nominal speed.

Force mode
The force mode is used in the following situations:
–
For clamping and holding workpieces, as well as for pro-
cesses where workpieces must be aligned (e.g. to a fixed
stop).
–
Pressing and joining processes.
–
Special functions where (e.g.) workpieces must be probed
in order to obtain position values.
