Reference
Drive IOS Limit This signal represents the hard-coded threshold at which an
Inspection Overspeed will be tripped. 150fpm.
Drive IOS Param Limit This signal represents the user-configurable threshold (Safety
screen) at which an Inspection Overspeed will be tripped.
Encoder Signal Raw encoder speed signal.
Field Active Status High = motor field control enabled.
Field Command (Control) Motor field composite command.
Field Control Path MCE internal diagnosis only.
Field Current Feedback Filtered motor field current feedback signal.
Field Current Signal Raw motor field current feedback signal.
Field Error Motor field error signal.
Field Integral Command Motor field integral command.
Field Integral Gain Motor field integral gain.
Field Proportional Command Motor field proportional command.
Field Proportional Gain Motor field proportional gain.
Field Voltage Feedback Filtered motor field voltage feedback signal.
Field Voltage Signal Raw motor field voltage feedback signal.
Load Weigher (Raw) Analog load weigher signal, after amplification (adjusted by
trimpot LW ADJ), at test point TP_LW on the CTP (cartop) board.
Load Weigher (Signal) The controller’s internal representation of the Load Weigher
(Raw) signal.
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 4-17.
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.
Over Current Power Armature power accumulated. Used for Loop Over Current.
Adjusted using Rated Loop Over Current and Loop Over Current
Fault Time.
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.
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.
Pattern (Command) Post-filtered pattern command signal. Please refer to “Following
Error Margin” on page 2-49. Please refer to “Verifying a One
Floor Run” on page 4-4. Please refer to “Pattern Scaling” on
page 4-7. Please refer to “Setting Pattern Parameters” on
page 4-14.
Pattern (Directional) Directional pattern signal.
Pattern (Filtered) Pre-filtered pattern signal. Please refer to “Tach Error Tripping
Threshold Adjustment” on page 2-50
