6 - 8
RUN MONITOR / FOLLOWER P3/3
The Run Monitor / Follower screen (page 3) monitor that are related to the Follower.
Cntrl Loop
Control Loop (MP-49) displays the present operating mode of the CX-1200. Only one type of loop can be active at a
time. These modes are automatically selected depending on the present system State (MP-50).
3 = Psn Hld (H-Stop Position Loop)
2 = Position Loop
1 = Velocity Loop
0 = Open Loop
State
State (MP-50) displays the present system operating state of the CX-1200 (see list below). Only one operating state
may be active at a time. To access either the “Run” or the “Jog” operating state, the F-Stop, R-Stop and H-Stop inputs
must be closed.
9 = Not Defined 8 = Diagnostics 7 = Not Defined
6 = Not Defined 5 = Jog 4 = Not Defined
3 = Run 2 = H-Stop 1 = R-Stop
0 = F-Stop
ScaledRef
Scaled Reference (MP-30) displays the reference speed, in Engineering Units per Time. This is the calculated setpoint
before the accel/decel ramps are applied. The placement of the decimal point is the same as the placement of the
decimal point in Master SP (CP-210).
RampedRef
Ramped Reference (MP-31) displays the speed command, in Engineering Units per Time. This is the output of the ramp
calculations. When the ramp has been completed, the RampedRef (MP-31) should equal the ScaledRef (MP-30).
Fb EU/Tm
Frequency Input 2 Engineering Units per Time (MP-06) displays the current speed of the Frequency Input 2 in the
Engineering Units per Time (EU/Tm) relative to the Pulses FI2 (CP-267), EU FI2 (CP-268) and Time Base (CP-209). The
placement of the decimal point is the same as the placement of the decimal point in EU FI2 (CP-268).
VelError
Velocity Error (MP-32) displays the difference between the RampedRef (MP-31) and Fb EU/Tm (MP-6). Displayed in
EU/Tm.
Fb Posn
Feedback Position (MP-20) displays the present value of the Feedback Position in Engineering Units, as specified by
Pulses FI2 (CP-267) and EU FI2 (CP-268). The placement of the decimal point is the same as the placement of the
decimal point in EU FI2 (CP-268).
PosnErr
Position Error (MP-33) displays the value, in engineering units, of the accumulated position error between the lead
(FI1) and the feedback (FI2) input signals. The placement of the decimal point is the same as the placement of the
decimal point in EU FI2 (CP-268).
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.
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).
