Enables denormalization for USS.

Possible Settings:

0Disabled

1Enabled

Index:

P2009[0] : Serial interface COM link

P2009[1] : Serial interface BOP link

Note:

If denormalization is enabled, the main setpoint (word 2 in PZD) is not interpreted as 100 % = 4000H, but as "absolute" instead (e.g. 4000H = 16384 means 163.84 Hz ) if this is a frequency. Denormalization (P2009 = 1) only works for frequencies and is intended for backwards compatibility with MM3.
