Code Modbus ID Parameter Application RO/RW
P2.2.30 2395 HOA On/Off 1,2,3 RW
Use this parameter for setting external input for disabling any control signal when the input is the off/open
position, when closed drive will follow the desired control signal. If the function is set for Normally Open
this will cause the drive to operate, if the function is set for Normally Closed then the drive will e in the off
location and not allow operation. Can be set to DigiIN: X indicates on board terminal inputs, DigiIN:A:IOX:X
indicates option boards in A slot, DigiIN:B:IOX:X indicates optional board 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.
P2.2.31 217 Second Motor Para Select 2,3 RW
Use this parameter selecting an external input for use of switching between motor parameter set 1(P1 Group)
and set 2 (P16 Group). When this function is set for Normally pen the drive will follow the first set of motor
parameters and when the input is set for Normally Closed it will used the Second Motor Parameter set. If an
input is used the function will follow the logic of the input being high/low. 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: the 2nd motor parameters is applied.
P2.2.32 2312 Parameter Set1/2 Sel 1,2,3 RW
Use this parameter for setting external input for selecting between the stored parameter set1 or
set2, this requires saving parameters to the stored sets via P21.1.3. When the function is set for Normally
Open the drive will use the standard Parameter Set 1 in the keypad, if the function is set for Normally Closed
the drive will follow Parameter Set 2 setting when stored to the keypad. 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.
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.
