221 Load Estimate
Displays the estimated load torque, which is the side effect of the speed observer and does not include torque to
accelerate or decelerate the motor if the inertia input is correct. The value is provided for display purposes.

222 Mtr Fdbk Sel Pri
Selects primary feedback device. The primary feedback device configuration must not be set to fault on an event
in order to allow operational feedback switch over to the alternate feedback device set in
Par 223 [Mtr Fdbk Sel
Alt].
Notes:
Par 485 [Motor Ctrl Mode] must be set to FOC for Sensorless feedback selection to be active. Selection 5 is
only available when compatible feedback option card is installed. This parameter was changed to non-linkable for
firmware version 3.001.

223 Mtr Fdbk Sel Alt
Selects alternate feedback device if the feedback device selected in Par 222 [Mtr Fdbk Sel Pri] fails.
Notes: Par 485 [Motor Ctrl Mode] must be set to FOC for Sensorless feedback selection to be active. Selection 5 is
only available when compatible feedback option card is installed. This parameter was changed to non-linkable for
firmware version 3.001.

224 TachSwitch Level
Sets the detection level for the automatic tach loss switch-over routine. A drop in feedback speed at this percent of
rated speed over 0.5 msec will cause a tach switch from primary to alternate feedback device. This feature is
enabled when bit 16 “Auto Tach Sw” in
Par 153 [Control Options] is selected.
Setting this level lower will make the tach switch detection more sensitive and lower the minimum speed at
which a tach switch can occur. Setting this level higher will make the tach switch less sensitive and raise the
minimum speed for tach switch detection.
Note: This parameter was changed to non-linkable for firmware version 3.001.

225 Virtual Edge/Rev
Set the edges per revolution (EPR) scaling for calculating motor position. Used in the calculation of the position
feedback such as
Par 229 [MtrPosit Stimulat].

228 MtrSpd Simulated
The motor speed output of the motor simulator. The motor simulator provides motor speed 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 [Mtr Fdbk Sel Pri] or Par 223 [Mtr Fdbk Sel Alt].

229 MtrPosit Simulat
The motor position output of the motor simulator. The motor 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 [Mtr Fdbk Sel Pri] or Par 223 [Mtr Fdbk Sel Alt].

230 Encdr0 Position
Displays the position feedback (accumulator) from encoder 0. The value changes by a value of four times (4x) the
Pulses Per Revolution (PPR) rating of the encoder for each full revolution of the encoder shaft. Used by the Velocity
Position Loop (VPL) to close the position loop if position control is selected.
