In order to obtain rapid high torque on startup, magnetic flux needs to already have been established in
the motor.
• In
[Continuous]
(FCt)
mode, the drive automatically builds up flux when it is powered up.
• In
[Not cont.]
(FnC)
mode, fluxing occurs when the motor starts up.
The flux current is greater than nCr (configured rated motor current) when the flux is established and is then
adjusted to the motor magnetizing current...

• In
[Not cont.]
(FnC)
mode:
- If an LI or a bit is assigned to the motor fluxing command, flux is built up when the assigned input or bit
is at 1.
- If an LI or a bit has not been assigned, or if the LI or bit assigned is at 0 when a run command is sent,
fluxing occurs when the motor starts.
• In
[No]
(FnO)
mode:
- If an LI or a bit is assigned to the motor fluxing command, flux is built up when the assigned input or bit
is at 1 and is suppressed when the assigned input or bit is at 0.
Parameter that can be modified during operation or when stopped.
CAUTION
Check that the motor will withstand this current without overheating.
Failure to follow these instructions can result in equipment damage.
