Goodrive35 inverters
Note: Rated slip frequency= (rated synchronous rotation speed of the motor-rated rotation speed
of the motor) *number of pole pairs/60.
4. Vibration control
Motor vibration occurs frequently when applying SVPWM control mode in the cases where high
power is needed. In order to settle this problem, Goodrive35 series inverters add two function
codes which are set to control the vibration factors. The user can set the corresponding function
code according to the vibration frequency.
Note: Bigger the set value, more effective is the control. If the set value is too big, overcurrent may
occur to the motor.

When the user selects the user-defined V/F curve function in Goodrive35 series inverters, they can
set the given channel of voltage and frequency and the corresponding ACC/DEC time, or the two can
be combined to form a real-time curve.
Note: the application of V/F curve separation can be used in many cases with various kinds of power
supply of the inverter. But the users should set and adjust the parameters with caution. Incorrect
parameters may cause damage to the inverter.
