PROGRAM OPTIONS MENU
The Program Options Menu is used to enable or disable the operator
accessible functions, load the Factory Settings, or enable/disable No
Feedback Detection.
The following flowchart shows only the Options portion:
OPERATOR ACCESS
The Operator Access menu is used with the program disable DIP switch or
an external User Input that is selected for the program disable function. When
an option is selected as NO, the operator can view the option but CANNOT
change the numeric value from the front panel keypad. (Refer to Front Panel
Accessible Programming With Program Disable for details.) The following
setpoint values can be disabled from front panel access programming;
Speed/Ratio Setpoint 1 and 2, Ramp Rate 1 and 2, Jog Speed, Jog Ramp,
Alarm Setpoint 1 and 2, and Gain.
The Setpoint Scroll Menu may also be disabled in the Operator Access
Menu. When disabled, the Setpoint Scroll Menu is not displayed.
Note: If a speed or ratio setpoint is disabled, the Setpoint Scroll Menu is not
accessible when that setpoint is the currently active speed/ratio setpoint.
FEEDBACK LOSS DETECTION (NO FBACK DET)
Used to prevent the MDC from ramping a motor to full speed if the
feedback signal is lost during operation or not present when RUN mode is
invoked. As soon as the MDC detects a loss of feedback, the display shows
“NO FEEDBACK” and the unit begins ramping down to zero speed. Enter
“YES” to enable and “NO” to disable Feedback Loss Detection.
Note: Feedback Loss Detection is automatically disabled in Open Loop Mode.
