Appendix C: Parameter Summary Numeric Quick Reference (continued)

MP-35 FeedFwd

Feedforward (MP-35) displays the estimated voltage command to the drive required achieve the commanded RampedRef
(MP-31). It is usually the major portion of the CO Volts (MP-37) signal.

Minimum Value: -15.00

Maximum Value: 15.00

Units: Volts

MP-36 Trim Out

Trim Out (MP-36) displays the value of the output of the PID compensator. Trim Out is displayed in Volts. Trim Out is
the sum of the conditioned error signals that, combined with the FeedFwd (MP-35), become the CO Volts (MP-37). Trim
Out is the combination of all three terms of the PID error correction algorithm.

Minimum Value: -15.00

Maximum Value: 15.00

Units: Volts

MP-37 CO Volts

Control Output Volts (MP-37) displays the present value, in volts, of the Control Output (CO_Sig) signal to the drive. It
is the combination of FeedFwd (MP-35) plus Trim Out (MP-36).

Minimum Value: -15.00

Maximum Value: 15.00

Units: Volts

MP-38 CO Bits

Control Output Bits (MP-38) displays the present value, in DAC bits, of the Control Output (CO_Sig) signal to the
drive. CO Bits is the CO Volts (MP-37) expressed in DAC bits.

Minimum Value: -32768

Maximum Value: 32767

Units: Bits

MP-39 CO Max Bits

Control Output Maximum Bits (MP-39) reflects the maximum allowed output in units of DAC bits. The value of CO Max
Volts (CP-271) determines this parameter, based on the conversion of 32767 bits = 15 VDC.

Minimum Value: 0

Maximum Value: 32767

Units: Bits

MP-40 Scaled Fb

Scaled Feedback (MP-40) displays the scaled feedback , which is scaled per ScFbDispEq (CP-250). The placement of
the decimal point is the same as the placement of the decimal point in Mater SP (CP-210) in "Master" and Follower SP
(CP-220) in "Ratio or Inverse Ratio".

Minimum Value: -9999999

Maximum Value: 9999999

Units: EU
