Description of Input Functions
0 Index Initiate
Executes the selected index. If Index Select Function #14 is not assigned, the Default Index
will initiate. (Factory set to Index 0.)
1 Home (0) Initiate
Executes Home Cycle #0 (see “Homes” on page 109).
2 Clear To Initiate
Clear to Initiate is intended to prevent unwanted motion during certain operations of a
machine cycle. This function, when assigned to an input line, prevents repeated and undesired
attempts at Index Initiate, Program Initiate or Home Initiate. It functions similar to edge
activation but is actually level activated.
The default polarity is (-) or normally off and the default signal sensitivity is edge sensitive.
The signal sensitivity can be changed to be level sensitive using the FI serial command. For
edge sensitivity send FI=0; for level sensitivity send FI=1.
Operation of this input with normally off (-) polarity and edge sensitivity (FI=0) is as follows:
• On power up index, Home and Program Initiate functions are blocked.
• Sending a Clear to Initiate input signal will allow one each Index, Home and Program
Initiate. To allow another Index, Home and Program Initiate after the first one, you must
send another low to high transition of the Clear to Initiate input signal to the drive.
Operation of this input when set to level sensitivity (FI=1) is as follows:
• When clear to initiate input is high (On), unlimited initiates are allowed. When low (Off),
initiates are inhibited.
3Hold
This function stops Index or Home motion as long as the input is active. Index or Home
motion resumes when this input is released. Decel time is set in Drive Limits (Stop/Hold
Decel Time). Accel time used to resume motion is the one in the Index or Home segment you
are interrupting. Program Jog is the only Jog function affected by Hold.
