5.2 "Basic" parameter group
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". When "Motor Nom
Frequency" (P-09) is changed, P-01 is set to the
value of P-09.
"Motor Nom Speed" (P-10) = 0, the maximum
speed limit will be displayed in Hz.
"Motor Nom Speed" (P-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
"f-max" (P-01). When "Motor Nom Frequency"
(P-09) is changed, P-01 is set to zero.
"Motor Nom Speed" (P-10) = 0, the minimum
speed limit will be displayed in Hz.
"Motor Nom Speed" (P-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" (P-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"
(P-09) to zero.
Determines the action taken by the drive in the
event of the drive enable signal being removed.
0: Ramping. When the enable signal is removed,
the drive will ramp to stop, with the rate controlled
by "t-dec" (P-04).
1: Coasting. When the enable signal is removed,
the drive output is immediately disabled, and the
motor will coast (freewheel) to stop.
2: Ramping. When the enable signal is removed,
the drive will ramp to stop, with the rate controlled
by "t-dec" (P-04). If the mains supply is lost the
drive will ramp to stop using the deceleration ramp
set by P-24. Condition: P-24 is set to a time which
is shorter than the one for discharging the DC link.
Otherwise the drive will trip due to "under
voltage".
3: AC flux braking. When stopping the drive, AC
flux braking is used to reduce the stopping time.
When energy optimization is activated, the motor
voltage is dynamically varied, dependent on load.
This results in reduced voltage being applied to the
motor on light load, significantly reduce energy
consumption.
This mode of operation is less suitable for dynamic
applications where the load conditions can
suddenly increase significantly.
