Parameter HSP determines the maximum speed the drive can operate. Parameter tFr determines the maximum value that HSP can be adjusted.
By default, tFr is set to 60Hz. When changing the Motor Frequency - bFr this changes tFr to 72Hz.
To increase the maximum speed above 72Hz - Go to the drc menu and Set parameter tFr. This can be adjusted up to 500Hz. After saving the change, go to the SEt menu > HSP and adjust up to the desired speed.
If your motor is a specialty motor that is rated for a frequency other than 50Hz. or 60Hz. such as a 300Hz. rated spindle motor, change parameter FrS under the DRC menu to match the rated frequency of the motor.
