This interlock bit will be set if the application task has set the Fault Reset bit (register
100/1100, bit 8) but has not cleared and then re-enabled any command bits.

More Than One Request

The More Than One Request bit is set if
more than one operating mode is requested
at a time in register 100/1100 (bits 0, 1, 2).

The bus is ready when the DC bus voltage is greater than the undervoltage
threshold value stored in local tunable UVT_E0% and has reached a steady state,
and feedback indicates that the pre-charge contactor has closed.

This interlock bit will also be set when turning on the drive if the bus enable bit
(register 100/1100, bit 4) has not been set. Refer to the SA3100 Power Modules
instruction manual (S-3058) for more information about internal DC bus control.
