■ C5-08: Speed Control Loop Integral Limit
Sets the upper limit for Speed Control Loop output as a percentage o f the rated torque.
No. Parameter Name Setting Range Default
C5-08 Speed Control Loop Integral Limit 0 to 400% 400%
■ 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. Parameter Name Setting Range Default
C5-16 Speed Control Loop D elay Time during Position Lock 0.000 to 0.500 s 0.000 s
■ C5-17, C5-18: Motor Inertia, Load Inertia Ratio
C5-17 and C5-18 determine the ratio o f the machine inertia and the inertia o f the motor being used.
No. Parameter Name Setting Range Default
C5-17 Motor Inertia 0.0001 to 600.00 kgm 2
Determined by C6-01 and
o2-04
C5-18
Load Inertia Ratio
0.0 to 6000.0 1.0
■ C5-19, C5-20: Speed Control Loop P Gain Time, I Time during Position Lock
These parameters adjust the responsiveness o f 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. Parameter Name Setting Range Default
C5-19
Speed Control Loop Proportional Gain Time during Position Lock
0.00 to 300.00 Determined by A1-02
C5-20
Speed Control Loop Integral Time during Position Lock
0.000 to 10.000 s 0.100 s
♦ C6: Carrier Frequency
■ C6-03: Carrier Frequency
Sets the carrier frequency.
No. Parameter Name Setting Range Default
C6-03 Carrier Frequency 1.0 to 15.0 kHz Determined by o2-04
■ C6-06: PWM Method
Determines how the drive should perform pulse width modulation.
No. Parameter Name Setting Range Default
C6-06 PW M Method 0 to 2 0
0: 2-phase/3-phase conversion
1: 2-phase modulation
2: 3-phase modulation
Note: The drive rated output current is reduced w ith setting 2. Contact Yaskawa or a Yaskawa representative for details.
■ C6-09: Carrier Frequency during Rotational Auto-Tuning
Determines the carrier frequency while performing Rotational Auto-Tuning. Although this parameter rarely needs to be
changed, when overcurrent problems occur when Auto-Tuning a low impedance motor, it may be helpful to set C6-03 to
a high value before setting C6-09 to 1.
No. Parameter Name Setting Range Default
C6-09 Carrier Frequency during Rotational Auto-Tuning 0 or 1 0
Setting 0: 5 kHz
Setting 1: Same value set to C6-03
