CP-74 DRIVE ENABLE LOGIC
Drive Enable Logic (CP-74) determines which conditions of the Ramped Reference (MP-46) and
the feedback will control the Drive Enable logic.
Enter "0" to deactivate the Drive Enable output (output high) when the Ramped
Reference is zero, and activate the Drive Enable output (output low) when the
Ramped Reference is not zero.
Enter "1" to deactivate the Drive Enable output when both the Ramped Reference and
the feedback are zero, and activate the Drive Enable output when the Ramped
Reference is not zero.
CP-75 OFFSET NULL
Offset Null is used to determine the analog input level where the offset term is zero (has no
influence).
CP-76 OFFSET AUTHORITY
Offset Authority determines the quantity of the offset term (amount of influence) for a given
analog input level.
CP-77 OFFSET POLARITY
Offset Polarity determines if the offset term is added or subtracted from the follower scaled
reference.
CP-79 SETPOINT LOCKOUT MASK
Setpoint Lockout Mask determines which setpoints are disabled when the keypad is locked out.
If CP-79 is set to "0", then none of the setpoints (CP-01 through CP-04) are disabled. If CP-79 is
set to "1", then all four of the setpoints are disabled. If CP-79 is set to "2", then CP-02 and CP-04
are disabled while CP-01 and CP-03 remain enabled.
