r975[2] and r975[10] for each drive component (NCU, ALM, power unit).
Example:
r975[2] = 230, r975[10] = 700 -> "230" & "700" -> firmware version is 02.30.07.00
Firmware version of all SMC or SMI modules
The firmware version of all SMC or SMI modules is read out in parameter r148[0...2] on the
relevant motor module.
Example:
r148[0] = 2300700, -> firmware version of the connected encoder module 1 is 02.30.07.00
