211 PeakDtct Status
Status of peak/level detectors. A peak detector sets its “Change” bit for one scan when it detects a peak. The” Change” bit is off when set or when the “Hold” bit is
on.
212 PkDtct1 In DInt
Integer input to the first peak/level detector.
Default:
Min/Max: 0

213 PkDtct1 In Real
Floating point input to the first peak/level detector.
Default:
Min/Max: 0.0000
-/+2200000000.0000
✓
RW Real
214 PeakDtct1 Preset
The first detector (in set or hold modes) compares this value to its input for level detection.
When the detector trips (in set mode) it transfers the value of this parameter to its output.
Default:
Min/Max: 0.0000
-/+2200000000.0000

215 PeakDetect1 Out
Output from the first peak/level detector.

216 PkDtct2 In DInt
Integer input to second peak/level detector.

218 PeakDtct2 Preset
The second detector (in set or hold modes) compares this value to its input for level detection.

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.
Units:
Default:
Min/Max: P.U.

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 3.01.
Default:
Options: 0 =
0 =
1 =
2 =
3 = “Encoder 0”
“Encoder 0”
4 = “Motor Sim”
“Encoder 1” 5 = “FB Opt Port0”
“Sensorless”
“Reserved”
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 3.01.
Default:

4 = “Motor Sim”
“Encoder 1” 5 = “FB Opt Port0”
“Sensorless”
“Reserved”
224 TachSwitch Level
Sets the detection level for the automatic tach loss switchover 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 3.01.
Units:
Default:
Min/Max: %

225 Virtual Edge/Rev
Set the EPR (Edges Per Revolution) scaling for calculating motor position. Used in the
calculation of the position feedback such as
Par 229 [MtrPosit Stimulat].
Units:
Default:
Min/Max: EPR

226 Motor Speed Est
Displays the estimated motor speed, calculated when the selected feedback is sensorless or
when encoderless ridethrough is enabled.

227 Motor Posit Est
Summation (or integration) of Par 226 [Motor Speed Est] scaled by the value in Par 225
[Virtual Edge/Rev].
