Ramp-up time
0 - 150.0
20
seconds
This is the time taken for the motor to accelerate from standstill to the maximum frequency. The
maximum frequency is set by parameter P013. Setting the ramp-up time too short can cause the
inverter to trip (Fault code F002 = overcurrent).

Ramp-down time

20
seconds
This is the time taken for the motor to decelerate from maximum frequency to standstill. The
maximum frequency is set by parameter P013. Setting the ramp-down time too short can cause the
inverter to trip (Fault code F001 = DC link overvoltage). This is also the period for which injection
braking is applied, if selected (refer to parameter P073 in Expert mode).

The value of this parameter 0, 1, 2 or 3) selects the mode of control of the inverter’s frequency
setpoint.
0 =
digital motorised potentiometer. the inverter runs at the frequency set in P005 (refer to Expert
mode) and can be controlled with the [up] and [down] keys. If P007 (see below) is set to 0, the
frequency can be increased or decreased by setting any two of the digital inputs (P051 to P055
or P356 - refer to Expert mode) to the values of 11 and 12.
1 =
Analogue. the inverter output frequency is controlled by analogue input signals (0-10V, 0/4-
20mA or potentiometer).
2 =
Fixed frequency. Fixed frequency is only selected by setting the value of at least one of the
digital inputs (P051 to P055 or P536 - refer to Expert mode) to the value of 6 or 18.
