Motor Vibration Reduction Rate; Lower Frequency Limit For Motor Vibration Reduction Function; Upper Frequency Limit For Motor Vibration Reduction Function - Sanken SVCO6 Instruction Manual

F6014

Motor vibration reduction rate

F6015 Lower frequency limit for motor
vibration reduction function
F6016 Upper frequency limit for motor
vibration reduction function
The function to reduce motor vibration under the occasions of vibration caused by mechanical sympathetic vibration in
vector control mode (speed sensor and speed sensorless).
Code No. Function Name
F6014 Motor vibration reduction rate
F6015 Lower frequency limit for motor
vibration reduction function
F6016 Upper frequency limit for motor
vibration reduction function
● The factory preset is F6014=0 (no function).
● When F6014 is set beyond 0, decrease the proportional gain of speed control within the range of 1st speed command
frequency set in
lower frequency limit for motor vibration reduction function (F6015) and upper frequency limit for motor
vibration reduction function (F6016).
● Motor vibration reduction rate is the reduction rate related to speed control ASR proportional gain (F6009). The
motor vibration cannot be eliminated even when the rate is set to be 25%, please decrease the setting of speed
control ASR proportional gain.
● Besides this function, the speed detection filter cut-off frequency (F6012) or Torque detection filter cut-off
frequency (F6013) can also be used to adjust and reduce the motor vibration.
Examples of setting
When command frequency is 15Hz-25Hz mechanical sympathetic vibration,
F6014=1(75%)
F6015=15.00Hz
F6016=25.00Hz
Note: The setting of lower frequency limit for motor vibration reduction function must be carried out referring to the
settings of upper frequency limit for motor vibration reduction function. (When the setting exceeds the setting in
upper frequency limit, the setting will be invalid because of the inconsistent detection.)
Reference parameter
