Data Type
Chapter 2
Values
✓ RW Real
Default: 50
Sets the depth for the Position Notch Filter. Attenuation is the ratio of the output to the input at Min/Max: 0/500
the notch frequency. An attenuation of 30 means that the notch output is 1/30th of the input at
the specified frequency.
Calculation: Attenuation = Input / Output

✓ RW Real
Default: 0.0
Min/Max: 0.0/500.0
Units:
Hz
Sets the center frequency of the Position Notch Filter.

PositDetct1 Stpt
Default: 0
Provides the set point for Position Watch 1. Position Watch 1 is enabled and configured with Min/Max: -/+2147483648
Par 740 [Position Control] bits 16 & 17. Position Watch 1 compares this value with Par 784
[Posit Dect1 In] and sets bit 8 “Posit Watch1” of Par 741 [Position Status] when the appropriate
condition is satisfied.
✓ RW 32-bit
Integer
781
PositDetct2 Stpt
Default: 0
Provides the set point for Position Watch 2. Position Watch 2 is enabled and configured with Min/Max: -/+2147483648
Par 740 [Position Control] bits 18 & 19. Position Watch 2 compares this value with Par 785
[Posit Dect2 In] and sets bit 9 “Posit Watch2” of Par 741 [Position Status] when the appropriate
condition is satisfied.
✓ RW 32-bit
Integer
782
Default: 200
In Posit BW
Sets the overall bandwidth of the In Position detector. The detector sets bit 10 “In Position” of Min/Max: 0/1000000
Par 741 [Position Status], when Par 769 [Position Error] is within this bandwidth for a sufficient
time, specified by Par 783 [In Posit Dwell]. A modest hysteresis count is added to the position
bandwidth after the position error is within specified limits.

In Posit Dwell
✓ RW Real
783
Default: 0.0040
Min/Max: 0.0000/10.0000
Units:
s
Position error must be within the value specified by Par 782 [In Posit BW] for this amount of
time before the In Position detector sets bit 10 “In Position” of Par 741 [Position Status]. A
momentary out-of-position indication will reset the internal timer and clear the In Position
status bit.
784
Default: 0
Posit Dect1 In
Provides the input variable for Position Watch 1. Position Watch 1 is enabled and configured Min/Max: -/+2147483648
with Par 740 [Position Control] bits 16 & 17. Position Watch 1 compares this value with Par 780
[PositDetct1 Stpt] and sets bit 8 “Posit Watch1” of Par 741 [Position Status] when the
appropriate condition is satisfied. A default link connects this parameter to Par 763 [Position
Actual].

Sync Loss
Bit 0 “Sync Pulse” will go high for 0.5ms latching the Sync Generator inputs to the Sync Generator outputs. The period at which this bit is set is determined by Par 787
[Xsync Gen Period].
Note: Bit 1 was changed to “Reserved” for firmware version 2.004.

Default: 0
Provides the input variable for Position Watch 2. Position Watch 2 is enabled and configured Min/Max: -/+2147483648
with Par 740 [Position Control] bits 18 & 19. Position Watch 2 compares this value with Par 781
[PositDetct2 Stpt] and sets bit 9 “Posit Watch2” of Par 741 [Position Status] when the
appropriate condition is satisfied. A default link connects this parameter to Par 763 [Position
