Programming and Parameters 3-19
59 Inertia Torq Add
The torque reference output generated by the inertia compensator. This torque level is
modified by Par 57 [InertiaAccelGain] and Par 58 [InertiaDecelGain]. A value of 1.0
represents rated torque of the motor.

-/+8.0000 Real
60 DeltaSpeedScale
Multiplier in the Inertia Compensation function - affects the value of Par 59 [Inertia Torq Add].
Use in center winder and unwind applications to compensate for roll diameter build-up.
Default:
Min/Max: 1.0000

61 Virt Encoder EPR
Equivalent Edges Per Revolution (EPR) or line count of a virtual encoder. A virtual encoder is
a position reference whose input comes from speed reference. It accumulates pulses at the
same rate as a real encoder of identical Pulses Per Revolution (PPR). Enter the equivalent
PPR.
For example: Enter 1024 EPR to match an encoder with 1024 PPR.

Integer
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.
Default:
Min/Max: 0

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.
Default:
Min/Max: 0

Integer
70 MtrSpd Sim Posit
The motor position output of the motor simulator. The simulator provides motor position
information during setup and troubleshooting when actual motor control is not desired or
possible. To use the motor simulator, enter a value of 4 in Par 222 [Motor Fdbk Sel].
Default:

72 Scaled Spd Fdbk
Displays the product of the speed feedback and Par 73 [Spd Fdbk Scale]. This parameter is
for display only.

73 Spd Fdbk Scale
A user adjustable scale factor (multiplier) for speed feedback. It is multiplied with speed
feedback to produce Par 72 [Scaled Spd Fdbk].

Summation (or integration) of Par 74 [Motor Spd Est] scaled by the value in Par 226 [Virtual
Edge/Rev].

76 MtrSpd Simulated
The motor speed output of the motor simulator. The simulator provides motor speed
information during setup and troubleshooting when actual motor control is not desired or
