MP-44 DEVIATION (ERROR)

Deviation (MP-44) displays the difference between the Ramped Reference (MP-46) and the

Feedback Frequency (MP-43) measured in units of hertz (pulses per second). Deviation is not

averaged or filtered; it is the ten millisecond frequency calculation prior to the display update.

MP-45 SCALED REFERENCE

The Scaled Reference (MP-45) is the scaled setpoint number converted to hertz. It is the

calculated value that is input to the Acceleration/Deceleration routine. This parameter may

display numbers that are larger than 9999. These larger values are displayed with two decimal

places. For example, 10,000 hertz is displayed as “10.00.”.

MP-46 RAMPED REFERENCE

The Ramped Reference (MP-46) is the calculated output of the Acceleration/Deceleration routine

in hertz. It is the setpoint input to the PID compensation routine. This parameter may display

numbers that are larger than 9999. These larger values are displayed with two decimal places.

For example, 10,000 hertz is displayed as “10.00.”

MP-47 DRIVE OUTPUT

The Drive Output (MP-47) displays the drive output level to the motor (J3 pin 1, 2). Drive Output

is displayed as a percentage; 100 represents 100% of the drive output.

MP-48 TRIM OUTPUT

The Trim Output (MP-48) is the calculated output of the PID Compensation routine. The Trim

Output added to the feedforward equals the Speed Command Output (MP-47). The Trim Output

(MP-48) is represented in DAC (Digital-to-Analog Converter) bits, for example 4095 equals 100%

output, 2048 equals 50% output.

MP-49 PIDF OUTPUT

The PIDF Output (MP-49) is the total calculated output of the PID Compensation routine added

to the feedforward. The PIDF Output is represented in DAC (Digital-to-Analog Converter) bits

where 4095 equals 100% output, 2048 equals 50% output, etc.
