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.
