user can adjust the Volt/Frequency ratio according to V/F pattern of specialized
motors and load characteristics.
Acc. Pattern
[V/F Pattern: 'Linear']
Voltage: 0-100% (Default:25,50,75100), Frequency: 0-400Hz (Default:
15,30,45,60)
These functions are available only when 'User V/F' is selected in F30 [V/F
pattern]. Users can make the custom V/F pattern by setting four points between
F23 [Starting Frequency] and F22 [Base Frequency]. The four points of voltage
and hertz are set in percent of H70 – [Motor rated voltage]. It cannot be set above
F21 – [Max frequency].
The values of the lower-numbered parameters cannot be set above those of
higher-numbered.
