The DacRemP DISPTC graph chart provides a means for monitoring torque commands required for each
motor for diagnostic purposes and verifying antenna balance. By observing each trace, the required drive of
the antenna via the motor driver PCB may be established.
Fine Balance and Monitoring Motor Drive Torque
•
To view the Torque Commands, select the graph chart.
•
This chart displays the Torque Command errors for each axis via three traces, CL (Cross Level), LV
(Elevation), and AZ (Azimuth), at a fixed 0.195 amps/vertical division.
•
In all axes, tracing centered on the reference line means that that axis drive is neutral. Tracing
above the reference line means that that axis is being driven CCW. Tracing below the reference
line means that that axis is driving CW.
•
A normal trace display will be ± 1 divisions from the red reference line while under calm sea
conditions and with DishScan® Drive turned off, as shown below.
•
The Cross Level displayed above the reference line indicates that the CL axis is being driven CCW
(Left in CL).
Example: The antenna pictured in the screen capture below is imbalanced so that it is “Right Heavy”.
The CL trace is plotting above the red reference line, indicating that CCW drive is required to keep
the Cross-Level beam level to the horizon.
•
The Level display will plot below the reference line when the antenna requires CW drive (Up in
elevation).
