YASKAWA TOEPYAIH6B01A HV600 AC Drive Narrow Bypass Installation & Startup
Sets the gain for the torque compensation function. Use this parameter value for motor 1 when you
operate multiple motors.
Sets the torque compensation delay time. Usually it is not necessary to change this setting.
Sets the carrier frequency for the transistors in the drive.
1 : 2.0 kHz
2 : 5.0 kHz
3 : 8.0 kHz
4 : 10.0 kHz
5 : 12.5 kHz
7 : Swing PWM1 (Audible Sound 1)
8 : Swing PWM2 (Audible Sound 2)
9 : Swing PWM3 (Audible Sound 3)
A : Swing PWM4 (Audible Sound 4)
B : Leakage Current Rejection PWM
F : User Defined (C6-03 to C6-05)
Note:
• The carrier frequency for Swing PWM 1 to 4 is equivalent to 2.0 kHz. Swing PWM applies a
special PWM pattern to decrease the audible noise.
• Setting B uses a PWM pattern that decreases the leakage current that the drive detects over long
wiring distances. This can help decrease alarm detection and decrease problems with the current
monitor from leakage current over long wiring distances.
Sets the upper limit of the carrier frequency. Set C6-02 = F [Carrier Frequency Selection = User
Defined (C6-03 to C6-05)] to set this parameter.
Sets the lower limit of the carrier frequency. Set C6-02 = F [Carrier Frequency Selection = User
Defined (C6-03 to C6-05)] to set this parameter.
Sets the proportional gain for the carrier frequency. Set C6-02 = F [Carrier Frequency Selection =
User Defined (C6-03 to C6-05)] to set this parameter.
