■ C5-08: Speed Control Loop Integral Limit
Sets the upper limit for Speed Control Loop output as a percentage of the rated torque.
■
C5-16: Speed Control Loop Delay Time during Position Lock
Adjusts the delay applied to the torque reference output from Speed Control Loop during Position Lock. Increase this
setting gradually in increments of 0.01 when vibration is a problem. This parameter rarely needs to be changed.
■
C5-17, C5-18: Motor Inertia, Load Inertia Ratio
C5-17 and C5-18 determine the ratio of the machine inertia and the inertia of the motor being used.
■
C5-19, C5-20: Speed Control Loop P Gain Time, I Time during Position Lock
These parameters adjust the responsiveness of Speed Control Loop during Position Lock. Increase C5-19 and shorten
C5-20 if the motor rolls back immediately after the brake releases. Decrease C5-19 and lengthen C5-20 if vibrations
occur.
■
C5-50: Set Vibrational Frequency Filter
Mechanical resonance may cause a humming sound or vibration while the motor is running. A vibrational frequency filter
can be used to suppress certain audible noise or vibration due to mechanical resonance.
Sets the mechanical vibration filter frequency in units of 1 Hz. Set C5-50 to 0 (Hz) to disable the filter. A setting of 0 will
disable this parameter.
Note: Test equipment may be required to determine the mechanical resonance frequency. Setting C5-50 to an improper frequency will
result in ineffective filtering of the effects of mechanical resonance.
