PTP Vel Override
Point-To-Point Velocity Override
Provides multiplier to both forward P785 [PTP Fwd Vel Lmt] and reverse P786 [PTP Rev
Vel Lmt] speed limits. This parameter applies to the speed limits when the override bit
P770 [PTP Control] Bit 0 “Vel Override” is on.

PTP EGR Mult
Point-To-Point Electronic Gear Ratio Multiply
EGR multiplier (numerator) for position index output. The output applies to the point-
to-point command P784 [PTP Command].

PLL Control

Phase Locked Loop Control

RW 16-bit

Integer

Sets bits to configure the phase locked loop control.

Bit 0 “PLL Enable” – enables the phase locked loop control.
Bit 1 “Velocity FF” – enables the velocity feed forward path.
Bit 2 “Ext Vel FF” – enables the external velocity feed forward through the PLL external speed reference selected by the PLL external speed selection P796 [PLL Ext
Spd Sel].
Bit 3 “Accel Comp” – enables providing an element of acceleration compensation to the feed forward branch. This is not recommended for use with external inputs
because of increased noise.
Bit 4 “PCAM Enable” – enables PCAM function with the PLL function.
Bit 5 “PTP Enable” – enables point-to-point function with the PLL function.
Bit 6 “Prof Enable” – enables profiler function with the PLL function.
Only bits 4, 5, and 6 allow associating with the PLL function.
