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 “
Restoring Factory Default Settings” on page 6–8.
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)×=
