Logic Output
The Drive Enable output is controlled by the Ramped Reference (MP-46) and the
feedback. Drive Enable Logic (CP-74) determines which conditions of the Ramped
Reference (MP-46) and feedback will control the Drive Enable output. The Ramped
Reference (MP-46) is the calculated setpoint that is output from the Acceleration/
Deceleration routine.
The factory default 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.
