Min. frequency			0.00 Hz

(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 50.00 Hz

(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 10.00 s

(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 10.00 s

(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 5.00 s

(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).
