3.5 Start-up: HIPERDRIVE Hub
After connecting the supply voltage, the hub automatically performs a presence test.
During this test, the hub detects the ports to which drives are connected. For each
drive, the baud rate is set to the last value saved in the hub for the specific drive. The
“RS485 message complete time” (time after which the drive evaluates a received
message) is set to a value corresponding to the desired baud rate. The RS485
address of the drive is set to 1 (steady-state).
In addition, the hub loads the most recently saved information about the ports at
which drives were most recently required, i.e. were released for issuing run
commands.
If at least one drive requested recently is not found, the LED RS485 is illuminated red.
If precisely the number of drives requested recently is found, the LED RS485 is
illuminated green.
If more drives than last required are found, the LED RS485 flashes green (frequency
2 Hz).
In the delivery state, no drive is
marked as “required”.
A drive must first be “required” at the hub in order to execute run
commands. Fo
r the drive “n”, this is done by setting SDO
( (n-1) * 0x80) to 1.
The presence test can also be repeated at any time after switching on the supply
voltage by setting SDO #200D to -3.
