Therefore, if the surrounding noise is greater than the motor noise, lower the carrier frequency to
reduce the temperature rise. Although the motor has quiet operation in the higher carrier
frequency, consider the entire wiring and interference.
 When the carrier frequency is higher than the default, decrease the carrier frequency to protect
the drive. Refer to Pr. 06-55 for related setting and details.
 The setting upper limit of carrier frequency rises with the frequency command, it is frequency
command * 10 lowest sampling point. For example, when the frequency command is set as
600Hz, the minimum carrier frequency (Pr.00-17) can only be set to 6kHz (600Hz*10); when the
frequency command is less than 200Hz, the minimum carrier frequency (Pr.00-17) can only be
set to 2kHz.
PLC Command Mask

 Determines if frequency command or control command is locked by PLC
Master Frequency Command (AUTO) Source / Source Selection of the PID Target
Settings
 Set the master frequency source in AUTO mode.
 Pr. 00-20 and Pr. 00-21 are for setting the frequency source and operation source in AUTO mode.
Pr. 00-30 and Pr. 00-31 are for setting the frequency source and operation source in HAND mode.
You can switch the AUTO / HAND mode with the keypad KPC-CC01 or the multi- function input
terminal (MI).
 The default for the frequency source or operation source is for AUTO mode. It returns to AUTO
mode whenever you cycle the power. If you use a multi-function input terminal to switch between
AUTO and HAND mode, the highest priority is the multi-function input terminal. When the
external terminal is OFF, the drive does not accept any operation signal and cannot execute JOG.
 When Pr. 00-20=4, the pulse input without direction command includes PG and MI8 input.
