7.2.2.10. Polarization Parameters

The Polarization menu allows for the configuration of the polarization axis. Options

include the setting of the pot zero, and the pot factor, as well as the skew adjustment

and stow limit functionality, the polarization offset, slow speed, and current limits for fast

and slow speeds.

Fig. 76: Maintenance - Polarization Parameters

Limit Switches (ST_DIS, LR_DIS)

Allows the enabling and disabling of the ST (STOW), LR (Polarization Left and Right

Limits), and SK (Skew adjustment) limits.

For the ST, and the LR limits, a check mark in the box implies the limit has been

DISABLED. By default the boxes are left unchecked. Please be advised that disabling

any of these limits should be done under the direct supervision of a c-com technical

support representative.

The SK_EN (Skew Adjustment) represents the 3-db drop test to optimize the polarization

angle. Checking this box will ENABLE the skew adjustment.

Note: The LR limit is for future development purposes, and is not functional at the time

of publication.

Current Settings

H_P_C (9) and L_P_C (6) represent high platform current (Amps) @ speed 9, and low

platform current @ speed 6 respectively. A software controlled current protection for the

Mobile Platform’s elevation motors. For Motor Speeds that are not listed (Speed 1, 2, 4,

5, 7, 8), the Current Limit for those speeds is calculated using a percentage of the

Current Limit @ speed 6 and 9. See appendix 3, table 5 for the default current limits for

all iNetVu

Mobile Platforms.

• Current Limit 8 – 90% of Current Limit 9

• Current Limit 7 – 80% of Current Limit 9

• Current Limit 5 – 90% of Current Limit 6

• Current Limit 4 – 80% of Current Limit 6
