C6: Carrier Frequency - YASKAWA L1000A Technical Manual

5.3 C: Tuning

◆ C6: Carrier Frequency

C6-03: Carrier Frequency
■
Sets the carrier frequency.
No.
C6-03
■ C6-06: PWM Method
Determines how the drive should perform pulse width modulation.
No.
C6-06
Setting 0: 2-phase/3-phase conversion
Setting 1: 2-phase modulation
Setting 2: 3-phase modulation
Note: The drive rated output current is reduced with 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.
C6-09
Setting 0: 5 kHz
Setting 1: Same value set to C6-03
C6-21: Inspection Operation Carrier Frequency
■
Sets the carrier frequency during Inspection Run.
No.
C6-21
Setting 0: Use the value set to C6-03
Setting 1: 2 kHz
C6-23: Carrier Frequency during Initial Motor Pole Search
■
Sets the carrier frequency when estimating the initial polarity.
No.
C6-23
Setting 0: 2 kHz
Setting 1: Use the value set to C6-03
C6-31: Carrier Frequency during Rescue Operation
■
Note: Available in drive software PRG: 7016 or later.
Sets the carrier frequency during Rescue Operation.
No.
C6-31
Setting 0: Use the value set to C6-03
Setting 1: 2 kHz
