[DigIn TermBlk 03] default. Select 2-Wire REV for this input.
Select this option and set P046, P048 or P050 [Start Source x] to 2 “DigIn TrmBlk” to
configure [Start Source x] to a 2-wire run reverse mode. Also see t064 [2-Wire Mode] for level
trigger settings.
For PowerFlex 523 drives, this setting will be disabled If [DigIn TermBlk 03] is set to
7 “Preset Freq”.
51 “3-Wire Dir”
(only for DigIn TermBlk 03)
Select 3-Wire Dir for this input.
Select this option and set P046, P048 or P050 [Start Source x] to 2 “DigIn TrmBlk” to change
the direction of [Start Source x].
For PowerFlex 523 drives, this setting will be disabled If [DigIn TermBlk 03] is set to
7 “Preset Freq”.
52 “Pulse Train”
(PF523: only for DigIn TermBlk 05)
(PF525: only for DigIn TermBlk 07)
Select pulse train for this input.
Use P047, P049 and P051 [Speed Referencex] to select pulse input.
Jumper for DigIn TermBlk 05 or 07 Sel must be moved to Pulse In.

t064 [2-Wire Mode] Related Parameter(s): P045, P046, P048, P050, t062, t063
Stop drive before changing this parameter.
Programs the mode of trigger only for t062 [DigIn TermBlk 02] and t063 [DigIn TermBlk 03] when 2-wire option is being selected as P046, P048 or P050 [Start Source x].
Options 0 “Edge Trigger” (Default) Standard 2-Wire operation.
1 “Level Sense” • I/O Terminal 01 “Stop” = Coast to stop. Drive will restart after a Stop command when:
– Stop is removed
and
– Start is held active
• I/O Terminal 03 “Run REV”
2 “Hi-Spd Edge”
• Outputs are kept in a ready-to-run state. The drive will respond to a Start command within 10 ms.
• I/O Terminal 01 “Stop” = Coast to stop.
• I/O Terminal 03 “Run REV”
3“Momentary” • Drive will start after a momentary input from either the Run FWD input (I/O Terminal 02) or the Run REV input (I/O Terminal
03).
• I/O Terminal 01 “Stop” = Stop according to the value set in P045
[Stop Mode].
ATTENTION: Hazard of injury exists due to unintended operation. When t064 [2-Wire Mode] is set to
option 1, and the Run input is maintained, the Run inputs do not need to be toggled after a Stop input for
the drive to run again. A Stop function is provided only when the Stop input is active (open).
ATTENTION: When operating in 2-Wire Level Sense (Run Level), the PowerFlex 523 and PowerFlex 525
drive should only be controlled from the Digital Input Terminal Blocks. This should NOT be used with any
other DSI or Network device.
There is greater potential voltage on the output terminals when using this option.
