Bit 13, Voltage OK/limit exceeded:
Bit 13 = "0" means that there are no voltage warnings.
Bit 13 = "1" means that the DC voltage in the frequency converter's intermediate circuit is too low or too high.
Bit 14, Torque OK/limit exceeded:
Bit 14 = "0" means that there are no current/torque warnings or errors.
Bit 14 = "1" means that there is a current/torque warning or error.
Bit 15, Thermal warning:
Bit 15 = "0" means that there is no thermal warning or error.
Bit 15 = "1" means that one of the thermal limits has been exceeded.
5.6.5 Bus Speed Reference Value
The speed reference value is transmitted to the frequency converter in a rel-
ative value in %.
The value is transmitted in the form of a 16-bit word; in integers (0-32767) the
value 16384 (4000 Hex) corresponds to 100%. Negative figures are formatted
by means of 2's complement.
The Actual Output Frequency (MAV) is scaled in the same way as the bus
reference.
The reference and MAV are scaled as follows:
