Normal and Fault Condition LED Messages

Motor Direction Status

When the controller is running, two pairs of LED segments are directly related to com- mand informations to the Power Output stage. The position and meaning of the segments is shown in the figure below.

Motor 2		Lit: Forward
Direction		Off: Reverse
Direction		Off: Reverse

FIGURE 1. Each command bit is wired to 2 LED segments

Motor 1		Lit: Forward
Direction		Off: Reverse
Direction		Off: Reverse

Note that the display does not provide Power information. Therefore it is possible that the motor be stopped while the display indicates that the direction is forward. In such a situa- tion is set to apply the power in the forward direction to the output stage but the motor is stopped because the applied power is zero.

The LED can display a total of 5 patterns summarized in Table 14.
