Logic Output
Drive Enable activates the motor drive based on the Ramped Reference (MP-46) and
the feedback. The Ramped Reference (MP-46) is the calculated setpoint that is output
from the Acceleration/Deceleration routine.
Drive Enable Logic (CP-74) determines which conditions of the Ramped Reference
(MP-46) and feedback will control the Drive Enable output. The factory defaults for
Drive Enable Logic (CP-74) is found in Table 3-27. To modify this default parameter,
refer to Table 3-28. If you are uncertain how to enter a Control Parameter, review the
Operations: Keypad section, page 3-3.
