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 set to option 3, 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).
There is greater potential voltage on the output terminals when using this option.
