Torridon HS Lite Drive Control Module - Technical Manual
Basic Concepts
Each switch on the Torridon control cards is called a 'Signal' and can be programmed to follow one
of 6 programmable delay profiles (called 'Sources'). This allows the user to sequence power and
signal connections to the drive in up to six programmable steps.
Each of the programmable delay profiles is called a control source, S1 to S6. For each control source
the user can set up a delay parameter. Three special sources (S0, S7 and S8) are also provided as
described in the table below.
Control Source Parameters for a power up event:
HOT_SWAP
DELAY
Once each delay period is set up, the user assigns each signal to follow the relevant control source,
then uses the "run:power up" and "run:power down" commands to initiate the hot-swap.
The BUSY bit 1 in the control register is set during a power up and power down operation. This may
be used to monitor for the completion of timed events.
