Danfoss iC2 - 6.1.8.5 Bus Speed Reference Value

Bit 13=0: There are no voltage warnings.
Bit 13=1: The DC voltage in the drive’s DC link is too low or too high.
Bit 14, Torque OK/Limit Exceeded
Bit 14=0: The motor current is lower than the current limit selected in P 2.7.1 Output Current Limit %.
Bit 14=1: The current limit in P 2.7.1 Output 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: 1 of the timers exceeds 100%.
6.1.8.5 Bus Speed Reference Value
Speed reference value is transmitted to the drive in a relative value in %. The value is transmitted in the form of a 16-bit word. The integer
value 16384 (4000 hex) corresponds to 100%. Negative figures are formatted using 2’s complement. The actual output frequency (MAV)
is scaled in the same way as the bus reference.
