BASIC MODE PARAMETERS
Parameter Function Range Default Units
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 0 - 150.0 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).

Frequency setpoint source
selection
0 - 2 0 -
The value of this parameter (0, 1 or 2) selects the mode of control of the inverter’s frequency setpoint.
0 = Digital motorised potentiometer (keypad control 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.
