F601 [Motor Current Limit]
10 to 110% of
the drive’s output
current rating
110%
CAUTION
RISK OF DAMAGE TO THE MOTOR AND THE DRIVE
z Check that the motor will withstand this current.
z Check that the profile mission complies with the derating curve given in the installation manual
Failure to follow this instruction can result in equipment damage.
Parameter F601 can be adjusted to limit current during motoring or braking.
Display in Current Limit Mode:
When the drive goes into current limit mode, it will:
Adjust the output frequency to limit the flow of motor current (down when motoring, up when braking).
Display the letter C and the output frequency flashing on the embedded software terminal, ex:
If parameter [Unit value selection] (F701) is set to 1 (see page 120
), parameter F601 will be adjusted in amperes. If param-
eter F701 is set to 0, parameter F601 will be adjusted as a percentage of the drive’s output rated current as listed on its
nameplate.
The setting of parameter [Switch. freq. level] (F300)
(see page 85) does not change the drive’s rated current for the sake of
this calculation.
Do not set parameter F601 below the no-load current rating of the motor.
