iControl DC
Load Weigher Balanced This signal is used to determine the amount of pretorque that
the controller needs to provide to the motor to help prevent roll-
back on takeoff. 0 = balanced load. Please refer to “Pretorque
Gain Adjustments” on page 4-22.
Load Weigher Feedback This signal represents the smoothed, processed Load Weigher
(Signal), captured with doors closed, just before departure.
Motor Contactor Status Indicates status (open/closed) of motor contactor. When the sig-
nal is high, the contacts are closed. When the contactor is closed
AND the motor field module is enabled, the motor will run.
Over Current Armature current signal used for Loop Over Current. Adjusted
using Rated Loop Over Current and Loop Over Current Fault
Time. Please refer to “Armature Overcurrent Overload Protection
Adjustment (System 12 SCR Drive)” on page 4-48.
Over Current Power Armature power accumulated. Used for Loop Over Current.
Adjusted using Rated Loop Over Current and Loop Over Current
Fault Time. Please refer to “Armature Overcurrent Overload Pro-
tection Adjustment (System 12 SCR Drive)” on page 4-48.
Over Current Power Threshold The armature power threshold above which a Loop Over Current
fault is generated. Adjusted using Rated Loop Over Current and
Loop Over Current Fault Time. Please refer to “Armature Over-
current Overload Protection Adjustment (System 12 SCR Drive)”
on page 4-48.
Over Current Threshold Armature current signal threshold above which over current
power is accumulated. Used for Loop Over Current. Adjusted
using Rated Loop Over Current and Loop Over Current Fault
Time. Please refer to “Armature Overcurrent Overload Protection
Adjustment (System 12 SCR Drive)” on page 4-48.
Pattern (Command) Post-filtered pattern command signal. Please refer to “Verify Pat-
tern Command and Drive Speed Feedback” on page 2-67. Please
refer to “Verifying a One Floor Run” on page 4-5. Please refer to
“Pattern Scaling (System 12 SCR Drive)” on page 4-9. Please
refer to “Setting Pattern Parameters” on page 4-19.
Pattern (Directional) Directional pattern signal.
Pattern (Filtered) Pre-filtered pattern signal. Please refer to “Tach Error Tripping
Threshold Adjustment” on page 2-68
Pattern (Interpolated) Interpolated (smoothed) pattern signal.
Pattern (Phase) The numbers displayed represent segments of the speed profile.
Please refer to “Shaping the Speed Profile” on page 4-17.
0 = Idle
1 = Initial Jerk
2 = Acceleration
3 = Low Roll Jerk (during acceleration, high speed is reached)
4 = Peak (High Speed)
5 = High Roll Jerk (during acceleration, high speed not reached)
6 = High/Low Roll Jerk (during deceleration)
7 = Deceleration
8 = Flare Jerk (transition from deceleration to leveling)
9 = Approach Jerk (transition from deceleration to leveling)
10 = Leveling
Pattern (Raw) Raw pattern signal. Please refer to “Speed Loop Gains (System
12 SCR Drive)” on page 2-66
