Unit Description / Notes
P133...P134 This feature (skip frequencies) prevents the motor from operating
[ 20.00Hz ]
permamently at speeds where the mechanical system enters into
resonance, causing high vibration or noise levels.
0.1Hz (99.99Hz) The enabling of this function is performed by setting P306 0.00.
P133...P134
[ 30.00Hz ]
0.1Hz (99.99Hz)
0.00...25.00Hz
[ 0.00 ]
0.01Hz
The passage through the skip speed band (2xP306) is made
according to the selected acceleration/deceleration rates.
This function does not operate properly when two skip frequencies
are overlapped.
Sets the address of the inverter for the serial communication.
