Master Mode - Analog Setpoint
The MLP-Drive can be scaled for Engineering Unit setpoint entry and Tach display
operation using the analog input for the setpoint. The following Control Parameters give
the MLP-Drive the necessary information for analog setpoint operation in Master mode.
Analog Input Allocation(CP-84)
Setting CP-84, Analog Input Allocation, to a value of "4" or "5" allocates
the analog input to be used as Master Setpoint 1 or Master Setpoint 2,
respectively.
Master Engineering Units (CP-20)
The actual value of the Master Engineering Units if the system were to
operate with an analog setpoint level of 10.0 volts. This is the maximum
calibrated analog input level (refer to Installation/Setup: Calibration,
Analog Input Calibration).
Note: The analog input does not need to operate to 10.0 volts full scale to be
used for setpoint replacement.
Max RPM Feedback (CP-34)
This is the maximum RPM of the feedback sensor shaft during system
operation.
PPR Feedback (CP-31)
The number of gear teeth or encoder lines on the follower feedback
sensor per revolution.
