Description
Sets the upper limit for the speed of the motor.
This can be set to any value between "f-min" and 5x the
"motor nom frequency" (P1-09).
Nominal motor speed (P1-10) = 0:
the maximum speed limit will be displayed in Hz.
Nominal motor speed (P1-10) > 0:
the maximum speed limit will be displayed in rpm.
Sets the lower limit for the speed of the motor
This can be set to any value between 0 and max. frequency
(P1-01).
Nominal motor speed (P1-10) = 0:
the minimum speed limit will be displayed in Hz.
Nominal motor speed (P1-10) > 0:
the minimum speed limit will be displayed in rpm.
Sets the acceleration ramp time in seconds.
The time interval set in "t-acc" represents the time taken to
accelerate from zero to "Motor Nom Frequency" (P1-09).
Sets the deceleration ramp time in seconds.
The time interval set in "t-dec" represents the time taken to
decelerate from "Motor Nom Frequency" (P1-09) to zero.
Determines the action taken by the drive in the event of the
drive enable signal being removed.
Possible values:
0: Coast to stop. When the enable signal is removed, the
drive output is immediately disabled, and the motor will
coast (freewheel) to stop.
1: Ramp to stop. When the enable signal is removed, the
drive will ramp to stop, with the ramp time set by "t-dec"
(P1-04).
2: AC flux braking. When stopping the drive, AC flux braking
is used to reduce the stopping time. In this mode the brake
chopper is disabled, even during normal operation.
Note: A brake chopper is activated via P4-05.
–
Defines the Motor rated voltage.
If P1-07 = 0 the DC bus voltage compensation is disabled (in
V/f mode only) and the output voltage will be equal to the
incoming supply voltage when operating at "Motor Nom
Frequency" (P1-09).
Motor nom current
By setting the "Motor Nom Current" in the drive, the motor
overload protection is configured to match the motor rating.
When the measured motor current exceeds "Motor Nom
Current", the decimal points on the display will flash to indi-
cate an overload condition.
If this condition persists, the drive will eventually trip,
preventing thermal overload of the motor. Display: I. t -trP
The rated frequency of the motor.
This is the frequency at which "Motor Nom Voltage" is
applied to the motor. Below this frequency, the applied motor
voltage will be reduced. Above this frequency the voltage
remains limited to "Motor Nom Voltage".
