Code Modbus ID Parameter Application RO/RW
P2.2.33 208 AI Ref Source Select 1,2,3 RW
Use this parameter for selecting an external input for switching between AI1 and AI2 reference signals
that are located on the control board. When this function is set for Normally Open the drive will follow
the AI1 input. If the function is set for Normally Close the AI2 input would then be active. Can be set
to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X indicates optional board inputs in A slot,
DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer Channel X. RO X Function allows for
having an input turn on without having to hard wire it to the physical relay output.
Closed contact: AI2 is selected for reference source.
Open contact: AI1 is selected for reference source.
P2.2.34 218 Bypass Start 1,2,3 RW
Use this parameter for selecting an external input for switching between bypass and drive modes. When
this input is enabled the Bypass output contactor is enabled, when disabled this relay opens and puts
drive in normal mode. When the input is enabled on the rising edge the bypass output contactor function
is enabled in the output functions on the drive. When this fault is set for Normally Open/Normally
Closed the drive will not activate the bypass relay output function due to the drive looking for a rising
edge trigger. Can be set to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X indicates optional
board inputs in A slot, DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer Channel X. RO X
Function allows for having an input turn on without having to hard wire it to the physical
relay output.
Closed contact: switch to bypass.
Open contact: switch to drive.
P2.2.35 1246 Bypass Overload 1,2,3 RW
Use this parameter for selecting an external input for faulting frequency converter when using an
external overload block, the relay would be fed into this input to fault the drive. When the function is set
for Normally Open the drive will not go into the fault state, if it is set for Normally Closed the drive will
go into this fault state and stay even if reset is applied. Input needs to be low to allow operation. Can
be set to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X indicates optional board inputs in
A slot, DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer Channel X. RO X Function allows
for having an input turn on without having to hard wire it to the physical relay output.
Closed contact: motor is over load in bypass.
Use TTF method to realize the above functions.
P2.2.36 550 PID1 Control Enable 2,3 RW
Use this parameter for selecting the digital input for turn on or off the PID1 controller. If the input is not
enabled when starting the drive with PID1 Controller set as the reference the drive output will not start.
Can be set to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X indicates optional board inputs
in A slot, DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer Channel X. RO X Function
allows for having an input turn on without having to hard wire it to the physical relay output.
Contact Close: Enables PID 1 control mode.
P2.2.37 553 PID2 Control Enable 2,3 RW
Use this parameter for selecting the digital input for turn on or off the PID2 controller. If the input is not
enabled when starting the drive with PID1 Controller set as the reference the drive output will not start.
Can be set to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X indicates optional board inputs
in A slot, DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer Channel X. RO X Function
allows for having an input turn on without having to hard wire it to the physical relay output.
Contact Close: Enables PID 2 control mode.
P2.2.38 351 PID1 Set Point Select 2,3 RW
Use this parameter for selecting an external input for selecting between Set point 1 and Set point 2
when in the PID control mode, depending on the PID Controller you are using this will all for multiple set
points. When this function is set for Normally Open and the drive is in PID mode, it will use the first PID
Set Point Reference. When the function is set for Normally Close the 1st PID Set Point will be active.
Can be set to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X indicates optional board inputs
in A slot, DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer Channel X. RO X Function
allows for having an input turn on without having to hard wire it to the physical relay output.
Closed contact: setpoint2 is selected for PID1.
Open contact:setpoint1 is selected for PID1.
P2.2.39 352 PID2 Set Point Select 2,3 RW
Use this parameter for selecting an external input for selecting between Set point 1 and Set point 2
when in the PID control mode, depending on the PID Controller you are using this will all for multiple set
points. When this function is set for Normally Open and the drive is in PID mode, it will use the first PID
Set Point Reference. When the function is set for Normally Close the 2nd PID Set Point will be active.
Can be set to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X indicates optional board inputs
in A slot, DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer Channel X. RO X Function
allows for having an input turn on without having to hard wire it to the physical relay output.
Closed contact: setpoint2 is selected for PID2.
Open contact:setpoint1 is selected for PID2.
