Drive Duty Mode And Carrier Frequency Selection: C6-01 And C6-02 - YASKAWA V1000 Quick Start Manual

WARNING! When 3-Wire sequence is used, set the drive to 3-Wire sequence before wiring the control
terminals and ensure parameter b1-17 is set to 0 (drive does not accept a run command at power up
(default)). If the drive is wired for 3-Wire sequence but set up for 2-Wire sequence (default) and if parameter
b1-17 is set to 1 (drive accepts a Run command at power up), the motor will rotate in reverse direction at
power up of the drive and may cause injury.
CAUTION! The motor will begin rotating as soon as the power is switched on. Proper precautions must be
taken to ensure that the area around the motor is safe prior to powering up the drive. Failure to do so may
result in minor or moderate injury.
Note: Run by Turning on/off the Power Supply. For safety reasons, the drive is initially set up not to
accept a run command at power up (b1-17 = "0"). If a run command is issued at power up, the
RUN indicator LED will flash quickly. To change this and have the run command issued by the
drive, change parameter b1-17 to 1

Drive Duty Mode and Carrier Frequency Selection:
C6-01 and C6-02
Drive Duty Mode Selection: C6-01
■
The drive has two different duty modes from which to select based on the load
characteristics. The drive rated current, overload capacity, carrier frequency, and maximum
output frequency will change depending upon the duty mode selection. Use parameter C6-01
(Duty Cycle) to select Heavy Duty (HD) or Normal Duty (ND) for the application. The
factory setting is ND.
Carrier Frequency Selection: C6-02
■
Fixed Carrier Frequencies
The carrier frequency can be set using parameter C6-02 as shown in table below.

Note: Settings 7 through A for parameter C6-02 use a Swing PWM equivalent to a 2 kHz audible
noise. This function turns the motor noise into a less obtrusive white noise.
Note: The upper limit for the carrier frequency is determined by drive capacity.
