SpeedRef
Sets or returns the speed reference in RPM.
Closed loop
Get/Set SpeedRef = Pr 0.01.021 (Scaled to 0 decimal places).
Open loop
Get SpeedRef = (Pr 0.01.021 * 60) / Pole Pairs (Scaled to 0 decimal places).
Set Pr 0.01.021 = (SpeedRef * Pole Pairs) / 60 (Scaled to 0 decimal places).
TorqueActual
Returns the actual load on the motor as a percentage of the rated motor load. This
attribute has 1 decimal place precision, a value of 1000 represents 100.0 % load.
Get Pr 0.04.020 (Scaled to 1 decimal place).
TorqueRef
Sets the load (torque) reference as % of rated motor load (torque). This attribute has 1
decimal place precision, so a value of 1000 represents 100.0 % load.
Set Pr 0.04.008 = TorqueRef / 10 (Scaled to 1 decimal place).
Get TorqueRef = Pr 0.04.008 * 10 (Scaled to 1 decimal place).
RefFromNet
Indicates the source of the speed reference.
TRUE if Pr 0.01.049 = 3 and Pr 0.01.050 = 1.
FALSE otherwise.
