PTP Reference
Point-To-Point Reference
Indicates output of the point-to-point position control as a reference of the position
control. When the speed/torque/position mode P313 [Actv SpTqPs Mode] is selected to
the point-to-point mode (Option 7) or the profiler mode (Option 6), this parameter
value appears on the position selected reference P722 [Psn Selected Ref].

PTP Ref Scale
Point-To-Point Reference Scale
Provides count per scale value for the point-to-point position reference. The value is a
multiplier for the point-to-point reference source selected by the reference selection
P775 [PTP Ref Sel].

PTP Index Preset
Point-To-Point Index Preset
Provides pre-set index value. The value sets to the point-to-point position command
P784 [PTP Command] when the point-to-point mode is index mode P771 [PTP Mode]
and the preset position bit P770 [PTP Control] Bit 3 “Preset Psn” is on.

PTP Setpoint
Point-To-Point Setpoint
Provides set point for the point-to-point position control. The value applies to the point-
to-point control when the point-to-point reference selection P775 [PTP Ref Sel] is P780.

PTP Accel Time
Point-To-Point Acceleration Time
Provides the ramp time for acceleration (time to go from zero to speed limit). The speed
limit is set by P785 [PTP Fwd Vel Lmt] and P786 [PTP Rev Vel Lmt].
