Chapter 2 Programming and Parameters
62 Virt Encdr Posit
A 32 bit pulse accumulator of the virtual encoder. The accumulated pulse count is equivalent to the hardware
accumulator of a real encoder. It accumulates at a rate of 4x the value placed in Par 61
[Virt Encoder EPR]. The
accumulator starts at zero upon position enable.

RO 32-bit
Integer
63 Virt Encdr Dlyed
One sample period delayed output of Par 62 [Virt Encdr Posit]. Used in some applications to phase synchronize
position reference through SynchLink. The master is delayed one sample while the downstream drives update
their position references – then all drives sample position simultaneously. The downstream drives do not select a
delay.

64 FricComp Spd Ref
Supplies a speed input to the Friction Compensation algorithm. This input is normally a speed reference from a
motion planner or ramped speed reference. It will trigger a torque feed forward response depending on its value.

65 FricComp Setup
Enter or write a value to configure the friction compensation algorithm. This is a packed word of 3 digits. Each
digit has a possible selection of 10 levels.
• The least significant digit sets the speed threshold in intervals of 0.0005 P.U. speed.
• The next (middle) digit sets the hysteresis band for the “units” digit in intervals of 0.0005 P.U. velocity.
• The most significant digit sets the number of time steps from stick to slip, each step is 0.002 sec.
Example: Value = 524 means: 5 time steps between stick and slip, each of 0.002 sec. duration, 2 counts of
hysteresis or 0.001 pu_speed (each count is 0.0005 pu_speed), and 4 counts or 0.002 pu_speed is the trigger
threshold (each count is 0.0005 pu_speed).

66 FricComp Stick
The torque needed to break away from zero speed. By nature of friction, the break away sticktion will always be
greater than the running friction.

67 FricComp Slip
The torque level to sustain very low speed – once “break away” has been achieved. By nature of friction, viscous
friction will always be less than sticktion.

68 FricComp Rated
The torque needed to keep the motor running at base speed and with no process loading. The friction
compensation algorithm assumes a linear or viscous component of friction between Par 67 [FricComp Slip] and
Par 68 [FricComp Rated].
