Bus Speed Reference Value - GE AF-600 FP Series Design And Installation Manual

RS-485 Installation and Set...
Bit 14, Torque OK/limit exceeded
Bit 14 = '0': The motor current is lower than the torque
limit selected in F-43 Current Limit. Bit 14 = '1': The torque
limit in F-43 Current Limit is exceeded.
Bit 15, Timer OK/limit exceeded
Bit 15 = '0': The timers for motor thermal protection and
thermal protection are not exceeded 100%. Bit 15 = '1':
One of the timers exceeds 100%.
All bits in the STW are set to '0' if the connection between
the Interbus option and the frequency converter is lost, or
an internal communication problem has occurred.

9.2.3 Bus Speed Reference Value

Speed reference value is transmitted to the frequency
converter in a relative 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.
Illustration 9.3 Actual Output Frequency (MAV)
The reference and MAV are scaled as follows:
