Hitachi L100 Series Instruction Manual page 100

NOTE: When DC braking is performed, the inverter automatically holds the carrier
frequency at 1 kHz.
NOTE: The carrier frequency setting must stay within specified limits for inverter-motor
applications that must comply with particular regulatory agencies. For example, a
European CE-approved application requires the inverter carrier to be less than 5 kHz.
B_84, B_85: Initialization codes – These functions allow you to restore the factory
default settings. Please refer to
B_86: Frequency display scaling – You can convert the output frequency monitor on
D_01 to a scaled number (engineering units) monitored at function D_07. For example,
the motor may run a conveyor that is monitored in feet per minute. Use this formula:
