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.

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

OFF3 ramp-down time

5.00 s

(enters the fast stop ramp-down time in s)

Defines ramp-down time from maximum frequency to standstill for OFF3 command.

Control mode

0

(enters the required control mode)

3Start quick commissioning only for motor data

NOTE

For P3900 = 1,2,3 P0340 is internally set to 1 and the appropriate data calculated (refer to the parameter list P0340).

End of quick commissioning/ drive setting

If additional functions must be implemented at the drive inverter, please use the instructions in Section 3.5.5 "Commissioning the application". We recommend this procedure for drives with a high dynamic response..
