Code Modbus ID Parameter Application RO/RW
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.
P2.2.40 202 DC Brake Active 1,2,3 RW
Use this parameter for selecting an external input for enabling DC brake on a closed contact. When enabled
this will cause the PowerXL drive inject DC voltage into the motor to assist in bring it to a stop. When this
function is set for Normally Open the drive will not activate the DC brake function. When Normally Closed is
used the drive will always have the DC brake function activated. 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: DC brake function is enable.
P2.2.41 219 Smoke Mode 2,3 RW
Use this parameter for selecting an external input for enabling the smoke purge preset speed to be enabled.
When this function is set for Normally Open the drive will not activate the Smoke Mode frequency. When
Normally Closed is used the drive will always run at the Smoke Purge Frequency. 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: drive is in smoke purge mode.
P2.2.42 220 Fire Mode 1,2,3 RW
Use this parameter for selecting an external input for enabling the drive fire mode feature where faults will
be ignored and preset speeds are given for reference commands to the drive, the reference are selectable in
the P15 Group. When this function is set for Normally Open or Normally Closed it will depend on the setting
in the Fire Mode parameter group, if the function activates on an open contact and this is set for Normally
Open it will always be in the Fire Mode, if Normally Closed is used then the function will always be off.
Vise versa will occur if Fire Mode is active on an Closed contact. 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: drive is in fire mode. Ignores all the faults.
Note: when Fire mode is enabled, this causes the drive to ignore all faults except hardware overcurrent, STO,
saturation fault. Warranty will be non valid in the case this is enabled and the drive causes issues to the
system.
P2.2.43 221 Fire Mode Ref 1/2 Select 1,2,3 RW
Use this parameter for selecting an external input for switching between fire mode speed reference 1 and
reference 2 which is set via P15.4 and P15.5. When this function is set for Normally Open and the drive is in
Fire Mode it will follow Fire Mode Ref 1, if the function is set for Normally Closed it will fallow Fire Mode Ref
2. 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: drive output reference frequency selection 2
