Error Code for the specific error. This parameter can be 
seen while online with PowerTools Pro EZ on the Errors 
view.
For details on the specific error code, refer to the user 
guide for the particular option module.
Slot 2 Error Status
Slot2.ErrorStatus
If the Unidrive SP trips due to an error in an option module 
populated in Slot 2, this parameter will store/display the 
Error Code for the specific error. This parameter can be 
seen while online with PowerTools Pro EZ on the Errors 
view.
For details on the specific error code, refer to the user 
guide for the particular option module.
Slot 3 Error Status
Slot3.ErrorStatus
If the Unidrive SP trips due to an error in an option module 
populated in Slot 3, this parameter will store/display the 
Error Code for the specific error. This parameter can be 
seen while online with PowerTools Pro EZ on the Errors 
view.
For details on the specific error code, refer to the user 
guide for the particular option module.
SlotX Encoder Lines Per Revolution
SlotX.EncoderLinesPerRev
This parameter is only available when an SM-Universal 
Encoder Plus option module has been populated in one of 
the Unidrive SP slots.
The X in “SlotX” defines the slot number that the 
SM-Universal Encoder Plus option module has been fitted 
in. For example, if the Universal Encoder Plus option 
module is in slot 2, the parameter would be named 
Slot2.EncoderLinesPerRev.
The EncoderLinesPerRev defines the resolution of the 
encoder hardware. This is equal to the number of lines on 
the encoder (pre-quadrature value). The range for the 
Lines Per Rev is 0 to 50000. This parameter is found on the 
SlotX view after a SM-Universal Encoder Plus option 
module has been selected for Module Type. For more 
information on this parameter, please refer to the 
SM-Universal Encoder Plus user guide (parameter x.10).
SlotX Simulated Encoder Denominator
SlotX.EncoderSimulationDenominator
This parameter is only available when an SM-Universal 
Encoder Plus option module has been populated in one of 
the Unidrive SP slots.
The X in “SlotX” defines the slot number that the 
SM-Universal Encoder Plus module has been fitted in. For 
example, if the Universal Encoder Plus module is in slot 2, 
the parameter would be named: 
Slot2.EncoderSimulationDenominator.
The SM-Universal Encoder Plus is capable of sending out 
a simulated encoder signal. To configure the simulated 
encoder signal, the user specifies a source parameter and 
a ratio multiplier. The multiplier allows the user to scale the 
source parameter before it is sent out the “Encoder Out” 
port. The multiplier is made up of a numerator parameter 
and a denominator parameter. The formula for the value 
sent out the encoder output is as follows:
Output = Enc. Sim. Source * (Enc. Sim. Numerator / Enc. 
Sim. Denominator)
The range for the Denominator is 0.0001 to 3.0000. This 
parameter is found on the SlotX view after a SM-Universal 
Encoder Plus module has been selected for the Module 
Type. For more information on this parameter, please refer 
to the SM-Universal Encoder Plus User Guide (parameter 
x.26).
SlotX Simulated Encoder Numerator
SlotX.EncoderSimulationNumerator
This parameter is only available when an SM-Universal 
Encoder Plus option module has been populated in one of 
the Unidrive SP slots.
The X in “SlotX” defines the slot number that the 
SM-Universal Encoder Plus option module has been fitted 
in. For example, if the Universal Encoder Plus module is in 
slot 2, the parameter would be named: 
Slot2.EncoderSimulationNumerator.

port. The multiplier is made up of a numerator parameter 
and a denominator parameter. The formula for the value 
sent out the encoder output is as follows:
Output = Enc. Sim. Source * (Enc. Sim. Numerator / Enc. 
Sim. Denominator)
The range for the Numerator is 0.0001 to 3.0000. This 
parameter is found on the SlotX view after a SM-Universal 
Encoder Plus module has been selected for the Module 
Type. For more information on this parameter, please refer 
to the SM-Universal Encoder Plus User Guide (parameter 
x.25).
SlotX Simulated Encoder Source
SlotX.EncoderSimulationSource
This parameter is only available when an SM-Universal 
Encoder Plus option module has been populated in one of
