Appendix A—Description of parameters

VARIABLE SPEED DRIVE SERIES III LIT-12012999—June 2018 www.johnsoncontrols.com

Code Modbus ID Parameter Application RO/RW

P2.2.47 226 Start Timer 3 2,3 RW

Use this parameter for selecting an external input for enabling the timer functions to begin

counting. When this function is set for Normally Open the drive will not start the Timer sequence. If

the function is set for Normally Close the Timer function will start. When assigned to an input the input

active will start the timer. 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: Timer1,Timer2 or Timer3 will be started.

P2.3.1 105 Preset Speed 1 1,2,3 RW

Use this parameter to set the Preset Frequency 1.

P2.3.2 106 Preset Speed 2 1,2,3 RW

Use this parameter to set the Preset Frequency 2.

P2.3.3 118 Preset Speed 3 1,2,3 RW

Use this parameter to set the Preset Frequency 3.

P2.3.4 119 Preset Speed 4 1,2,3 RW

Use this parameter to set the Preset Frequency 4.

P2.3.5 120 Preset Speed 5 1,2,3 RW

Use this parameter to set the Preset Frequency 5.

P2.3.6 121 Preset Speed 6 1,2,3 RW

Use this parameter to set the Preset Frequency 6.

P2.3.7 122 Preset Speed 7 1,2,3 RW

Use this parameter to set the Preset Frequency 7.

P2.3.8 117 Jog Reference 1,2,3 RW

Use this parameter to set the jogging speed set point, this speed is selected with the digital input

programmed for Jogging speed. When enabled the drive starts and ramps to this speed, input removed

drive stops.

This parameter’s value is automatically limited between minimum and maximum frequency.

P2.4.1 222 AI1 Mode 1,2,3 RW

Defines the analog input 1 source mode for current or voltage, also need to set DIP switches on control

board SW1.

0 = 0-20mA - current loop with an external supply the ground jumper is not required.

1 = 0-10V - If using the 10V supply on Terminal 1 of the drive, it will require a ground jumper from

Terminal 6 to the AI- input terminal 3.
