Bit 00, Control not ready/ready:
Bit 00 = "0" means that the adjustable frequency drive
has tripped. Bit 00 = "1" means that the adjustable
frequency drive controls are ready, but the power

Bus reference value:
The frequency reference value is transmitted to the
adjustable frequency drive in the form of a 16-bit word.
The value is transmitted as a whole number (0-32767).
16384 (4000 Hex) corresponds to 100%. (Negative
figures are formatted by means of 2's complement.)
The bus reference has the following format:
Parameter 203 = "0"
0-16384 (4000 Hex) ~ 0-100% ~ ref
Parameter 203 = "1"
- 16384 (...Hex) - + 16384 (4000 Hex) ~
- 1000 - + 100% ~ - ref
