Code Modbus ID Parameter Application RO/RW

P2.2.19 194 Run Enable 1,2,3 RW

Use this parameter for setting external safety start input that is required along with start command for

frequency converter to turn on output. When using this command if the function is set for Normally Open,

the drive will see this as a open input and not allow the drive to run due to no Ready. The default state being

Normally Closed indicates that the drive is in a Ready condition and will accept the start command. When

assigned to one of the DIGIN or Time channels it requires the input to be high to activate output. 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 = Start of motor enabled

Open contact = Start of motor disabled

P2.2.20 205 Preset Speed B0 1,2,3 RW

Use this parameter selecting the of the digital input for an external speed setpoint desired. Validating 3

digital inputs will allow for 7 preset speeds to be obtained. When switching between inputs it will follow

the acceleration and deceleration time. When all the inputs are set to Normally Open none of the preset

speeds will be enabled and the output will follow the control place reference command. If the function is set

for Normally Closed the drive will follow the preset speed assigned to the inputs enabled. When assigned to

one of the DIGIN on the control board or an installed option card it is looking for a high input to enable that

preset. 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.
