Min. frequency
(enters the minimum motor frequency in Hz)
Sets minimum motor frequency at which motor will run irrespective of frequency
setpoint. The value set here is valid for both clockwise and anticlockwise rotation.
Max. frequency
(enters the maximum motor frequency in Hz)
Sets maximum motor frequency at which motor will run irrespective of the
frequency setpoint. The value set here is valid for both clockwise and
anticlockwise rotation.
Ramp-up time
(enters the ramp-up time in s)
Time taken for motor to accelerate from standstill up to maximum motor
frequency (P1082) when no rounding is used. If a ramp-up time is parameterized
which is too low, then this can result in alarm A0501 (current limit value) or the
drive inverter being shutdown with fault F0001 (overcurrent).
Ramp-down time
(enters the deceleration time in s)
Time taken for motor to decelerate from maximum motor frequency (P1082) down
to standstill when no rounding is used. If the ramp-down time is parameterized too
low, then this can result in alarms A0501 (current limit value), A0502 (overvoltage
limit value) or the drive inverter being powered-down with fault F0001
(overcurrent) or F0002 (overvoltage).
OFF3 ramp-down time
(enters the fast stop ramp-down time in s)
Enters the time, for example, with which the motor should be braked from the
maximum frequency P1082 down to standstill for an OFF3 command (fast stop).
If the ramp-down time is parameterized too low, then this can result in alarms
A0501 (current limit value), A0502 (overvoltage limit value) or the drive inverter
being shutdown with fault F0001 (overcurrent) or F0002 (overvoltage).
