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:

 

Scaled output frequency (D_07)

Output frequency (D_01) Factor (B_86)
