FREQUENCY CONTROL
These Function Codes are used to avoid the
natural mechanical vibration of the load.
The three jump frequencies can be set
independently and are adjustable from 0 to
400 Hz.
53 JUMP Hz-1 FREQUENCY JUMP SETTING 0
54 JUMP Hz-2 FREQUENCY JUMP SETTING 0
55 JUMP Hz-3 FREQUENCY JUMP SETTING 0
56 JUMP HYSTR FREQUENCY JUMP HYSTERESIS 3
This setting determines the hysteresis
(jump width) of the jump frequency setting.
Adjustable from 0 to 30 Hz.
Example: Function Code 53 set at 20 Hz, Function
Code 56 set at 4 Hz. Output frequency will reach
18 Hz, jump to 22 Hz and continue ramping if input
reference is set above 20 Hz. On a decel, output
frequency will reach 22 Hz and jump to 18 then
continue to decel.
