· Setting Pr. 288  under Real sensorless vector control or vector control can limit the frequency command when the

frequency after droop compensation is negative.

0

(initial value),

10

Droop control is not exercised during acceleration/
deceleration.
Note that the frequency command after droop control is 
limited at 0.5Hz when the frequency command after 
droop control is negative.
Droop compensation amount is determined using the 
rated motor frequency as reference.

Droop control is not exercised during acceleration/
deceleration.
Note that the frequency command is limited at 0Hz when 
the frequency command after droop control is negative.
When Pr. 288 = "10", droop compensation amount is 
determined using the motor speed as reference.

1, 11

Droop control is always exercised during operation.
Note that the frequency command is limited at 0Hz when 
the frequency command after droop control is negative.
When Pr. 288 = "11", droop compensation amount is 
determined using the motor speed as reference.

2

Droop control is always exercised during operation.
Note that under vector control, the frequency command 
is not limited at 0Hz even when the frequency command 
after droop control is negative.
(The frequency command is limited at 0Hz under Real 
sensorless vector control.)

The maximum value of frequency after droop compensation is either 120Hz or Pr. 1 Maximum frequency , whichever is smaller.
