Level

1

Time taken for motor to accelerate from standstill up to maximum motor frequency (P1082) when no rounding is used.

Setting the ramp-up time too short can cause the inverter to trip (overcurrent).

P1120[1] : 2nd. Drive data set (DDS)

P1120[2] : 3rd. Drive data set (DDS)

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
