 From the table, we see that the PWM carrier frequency has a significant influence on the
electromagnetic noise, AC motor drive heat dissipation, and motor acoustic noise. Therefore, if
the surrounding noise is greater than the motor noise, lower the carrier frequency is good to
reduce the temperature rise. Although it is quiet operation in the higher carrier frequency, the
entire wiring and prevention of interference should be considered.
 When the carrier frequency is higher than the factory setting, must decreasing the carrier
frequency to protect the drive. Refer to Pr. 06-55 for the related setting and details.
PLC Command Mask
Factory Setting: Read Only
Settings bit 0: Control command forced by PLC control
bit 1: Frequency command forced by PLC control
 This parameter determines if frequency command or control command is locked by PLC.

Source of the Master Frequency Command (AUTO)
Factory Setting: 0
Settings 0: Digital keypad
1: Communication RS-485 input
2: External analog input (Refer to Pr. 03-00)
3: External UP / DOWN terminal
6: CANopen communication card
7: Digital keypad dial
8: Communication card (not includes CANopen card)
[Note]: Need to use with MO setting as 42, or use with KPC-CC01
 The AUTO / HAND mode can be switched by the keypad KPC-CC01 (optional) or multi-function
input terminal (MI) to set the source of the master frequency.

Pr. 00-20 and Pr. 00-21 are for the settings of frequency source and operation source in AUTO
mode. Pr. 00-30 and Pr. 00-31 are for the settings of frequency source and operation source in
HAND mode.
 The factory setting of frequency source or operation source is for AUTO mode. It will return to
AUTO mode whenever power on again after power off. If there is multi-function input terminal
used to switch AUTO / HAND mode, the highest priority is the multi-function input terminal. When
the external terminal is OFF, the drive will not accept any operation signal and cannot execute
JOG.
