P0640[0] Enter Motor Overload Factor
This defines the limit of the maximum output current as a %
of the rated motor current (P0305). This parameter is set,
using P0205 for constant torque, to 150 %, and for variable
torque, to 110 %.

P1080[0] Set Min. Frequency
Enters the lowest motor frequency with which the motor
operates independently of the frequency setpoint. The
value which is set here applies for both directions of
rotation.
P1082[0] Set Max. Frequency
Enters the maximum frequency to which, for example, the
motor is limited independently of the frequency setpoint.
The value which is set here applies for both directions of
rotation.
NOTE
You should check with your motor manufacturer if you
intend to operate above nominal motor frequency.
Lifetime and/or safety could be compromised if you go
too fast.
P1120[0] Set Ramp-Up Time
Enters the time with which, for example, the motor should
accelerate from standstill up to the maximum frequency
P1082. If the ramp-up time is set too low, this may result in
alarm A0501 (current limit active) or the drive tripping out
with fault F0001 (overcurrent).
