C5-08: Speed Control Loop Integral Limit
■
Sets the upper limit for Speed Control Loop output as a percentage of the rated torque.
No.
C5-08
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.
No.
C5-16 Speed Control Loop Delay Time during Position Lock
■ 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.
No.
C5-17
C5-18
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.
No.

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.
No.

<1> Available in drive software versions PRG: 7200 or later.
<2> The frequencies from 1 to 19 Hz cannot be set.
