11. Access the "Field Config" group and configure the following
parameters:
If the motor field power is supplied by an external source, set
Par 497 [Field Reg Enable] = 0 "Disabled". Otherwise, verify
that this parameter is set to 1 "Enabled" (default).
If you are utilizing field economy when the drive is stopped or
at zero speed, set Par 1407 [Field Econ Delay] to the desired
amount of time to elapse after the drive stops or reaches zero
speed before field economy becomes active (the value set in Par
468 [Min Fld Curr Pct]). The default value is 300 seconds.
Par 469 [Field Mode Sel] - select the desired field mode
(default = 0 "Base Speed", constant field current):
If you are utilizing field economy at zero speed, set 468 [Min
Fld Curr Pct] to the desired minimum field current for field
economy (default = 30%).
If you are operating the drive in field weakening mode, set Par
456 [Fld Weaken Ratio] = Motor nameplate base speed / Par 45
[Max Ref Speed] x 100.
Important: When operating the drive in field weakening mode, it is
