Field-Weakening
d6-01
Magnetic Field Weakening
Level
Field-Weak Lvl Sets the Drive output voltage when the multi-function input “field
weakening command” is input (H1-XX = 63). Sets as a percentage
taking the voltage set in the V/F pattern as 100%.

d6-02
Magnetic Field Frequency
Field-Weak Freq
Sets the lower limit (in Hz) of the frequency range where field
weakening control is valid. The field weakening command is valid
only at frequencies above this setting and only when output
frequency is in agreement with the current output frequency (speed
agree).

Magnetic Field Forcing Limit
Field Force Limit
Sets the upper limit of the excitation current command during
magnetic field forcing. A setting of 100% is equal to motor no-load
current, E2-03.

Input Voltage Setting
Input Voltage
Set to the nominal voltage of the incoming line. Sets the maximum
and base voltage used by preset V/F patterns (E1-03 = 0 to E),
adjusts the levels of Drive protective features (e.g. Overvoltage,
braking resistor turn-on, stall prevention, etc.).
DRIVE INPUT VOLTAGE (NOT MOTOR VOLTAGE)
MUST BE SET IN E1-01 FOR THE PROTECTIVE
FEATURES OF THE DRIVE TO FUNCTION PROPERLY.
FAILURE TO DO SO MAY RESULT IN EQUIPMENT DAM-

V/F Pattern Selection
V/F Selection
Set to the type of motor being used and the type of application.
The Drive operates utilizing a set V/F pattern to determine the
appropriate output voltage level for each commanded speed. There
are 15 different preset V/F patterns to select from (E1-03 = 0 to E)
with varying voltage profiles, base levels (base level = frequency
at which maximum voltage is reached), and maximum frequencies.
There are also settings for Custom V/F patterns that will use the
settings of parameters E1-04 through E1-13. E1-03 = F selects a
custom V/F pattern with an upper voltage limit and E1-03 = FF
selects a custom V/F pattern without an upper voltage limit.
