PROGRAMMING RX
3.13 Digital inputs
The function codes in the following table let you assign between a wide range of functions to any of the eight logic inputs for the
RX inverter. The functions C001 through C008 configure the terminals [1] through [8] respectively, terminal [FW] could not be
set and work always as Run forward or to start a Drive programing. The “value” of these particular parameters is not a scalar
value, but it is a discrete number that selects one option from many available options.
A016 O, O2, OI sampling 1 to 30
31 (with 500ms filter ±0.1 Hz hysteresis)
A111 O2 start frequency -400.00 to 400.00 Hz
A112 O2 end frequency -400.00 to 400.00 Hz
A113 O2 start ratio -100% to O2 end ratio
A114 O2 end ratio O2 start ratio to 100%

Function Name Description
01 RV Reverse run/stop ON Inverter is in Run Mode, motor runs reverse
OFF Inverter is in Stop Mode, motor stops
02 CF1 Multi-step speed setting binary 1 ON Binary encoded speed selection bit 3 to bit 0
03 CF2 Multi-step speed setting binary 2
04 CF3 Multi-step speed setting binary 3 OFF
05 CF4 Multi-step speed setting binary 4
06 JG Jogging ON Inverter is in Run Mode, output to motor runs at jog parameter frequency
07 DB External DC injection braking ON DC braking will be applied during deceleration
08 SET Set (select) 2nd control ON The inverter uses 2nd motor parameters for generating frequency output to motor
OFF The inverter uses 1st (main) motor parameters for generating frequency output to motor
09 2CH 2-step acceleration/deceleration ON Frequency output uses 2nd-stage acceleration and deceleration values
OFF Frequency output uses standard acceleration and deceleration values
11 FRS Free-run stop ON Causes output to turn OFF, allowing motor to free run (coast) to stop
12 EXT External trip ON When assigned input transitions OFF to ON, inverter latches trip event and displays E 12
OFF No trip event for ON to OFF, any recorded trip events remain in history until reset
13 USP USP function ON On power up, the inverter will not resume a Run command
OFF On power up, the inverter will resume a Run command that was active before power loss
14 CS Commercial switch ON Motor can be driven by commercial power
OFF Motor is driven via the inverter
15 SFT Soft lock ON The keypad and remote programming devices are prevented from changing parameters
OFF The parameters may be edited and stored
16 AT Analog input switching ON Refer to Analog Input selection
OFF
17 SET3 Set (select) 3rd control ON The inverter uses 3rd motor parameters for generating frequency output to motor
18 RS Reset inverter ON The trip condition is reset, the motor output is turned OFF, and powerup reset is asserted
OFF Normal power-ON operation
20 STA Start (3-wire start) ON Starts the motor rotation
21 STP Stop (3-wire stop) ON Stops the motor rotation
22 F/R FWD, REV
(3-wire forward/reverse)
ON Selects the direction of motor rotation: ON = FWD. While the motor is rotating, a change of F/
R will start a deceleration, followed by a change in direction
OFF Selects the direction of motor rotation: OFF = REV. While the motor is rotating, a change of F/
R will start a deceleration, followed by a change in direction
23 PID PID enabled/disabled ON Temporarily disables PID loop control. Inverter output turns OFF as long as PID Enable is
active (A071=01)
OFF Has no effect on PID loop operation, operates normally if PID Enable is active (A071=01)
24 PIDC PID integral reset ON Resets the PID loop controller. Main consequence is that integrator sum is forced to zero
26 CAS Control gain switching ON Control gain switching function
27 UP UP/DWN function accelerated ON Accelerates (increases output frequency) motor from current frequency
28 DWN UP/DWN function decelerated ON Decelerates (decreases output frequency) motor from current frequency
29 UDC UP/DWN function data clear ON Clears the UP/DWN frequency memory by forcing it to equal the set frequency parameter
F001. Setting C101 must be set=00 to enable this function to work
31 OPE Forced operator ON Forces the source of the output frequency setting A001 and the source of the Run command
A002 to be from the digital operator
OFF Source of output frequency set by A001 and source of Run command set by A002 is used
