P1120 Ramp-up time Min: 0.00
CStat: CUT Datatype: Float Unit: s Def: 10.00
P-Group: SETPOINT Active: first confirm QuickComm. Yes Max: 650.00
Time taken for motor to accelerate from standstill up to maximum motor frequency (P1082) when no
rounding is used.
f (Hz)
0
f max
(P1082)
t (s)
P1120
Setting the ramp-up time too short can cause the inverter to trip (overcurrent).
Note:
If an external frequency setpoint with set ramp rates is used (e.g. from a PLC). The best way to achieve
optimum drive performance is to set ramp times in P1120 and P1121 slightly shorter than those of the PLC.
Notice:
Ramp times will be used as follows:
P1060 / P1061 : JOG mode is active
P1120 / P1121 : Normal mode (ON/OFF) is active
P1060 / P1061 : Normal mode (ON/OFF) and P1124 is active
P1121 Ramp-down time Min: 0.00
CStat: CUT Datatype: Float Unit: s Def: 10.00
P-Group: SETPOINT Active: first confirm QuickComm. Yes Max: 650.00
Time taken for motor to decelerate from maximum motor frequency (P1082) down to standstill when no
rounding is used.

f max
(P1082)
t (s)
P1121
Notice:
Setting the ramp-down time too short can cause the inverter to trip (overcurrent (F0001) / overvoltage
(F0002)).
Ramp times will be used as follows:
P1060 / P1061 : JOG mode is active
P1120 / P1121 : Normal mode (ON/OFF) is active
P1060 / P1061 : Normal mode (ON/OFF) and P1124 is active
