Description / Notes
P003 •••• Ramp down time (seconds) 0 - 650.00
[25.00]
This is the time taken for the motor to decelerate from maximum frequency
(P013) to standstill.
Setting the ramp down time too short can cause the inverter to trip (fault
code F001 - overvoltage).
This is also the period for which DC injection braking is applied (see P073)

P004 ••••
Smoothing (seconds) 0 - 40.0
[0.0]
Used to smooth the acceleration/deceleration of the motor (useful in
applications where it is important to avoid ‘jerking’, e.g. conveyor
systems, textiles, etc.).
Smoothing is only effective if the ramp up/down time exceeds 0.3 s.

Note: The smoothing curve for deceleration is based on the ramp
up gradient (P002) and is added to the ramp down time set
by P003. Therefore, the ramp down time is affected by
changes to P002.
P005 ••••
Digital frequency setpoint (Hz) 0 - 120.00
[50.00]
Sets the frequency that the inverter will run at when operated in digital
mode. Only effective if P006 set to ‘0’.
P006
Frequency setpoint source
selection 0 - 2
[1]
Sets the control mode of the inverter.
0 = Digital. The inverter runs at the frequency set in P005.
If P007 is set to zero, the frequency may be adjusted by setting
any two of digital inputs P051 - P053 to values of 11 and 12.
1 = Analogue. The frequency is set via an analogue input signal
or the internal potentiometer.
2 = Fixed frequency or motor potentiometer. Fixed frequency is
only selected if the value of at least one binary input (P051 -
P053) = 6, 17 or 18.
Notes: (1) If P006 = 1 and the inverter is set up for remote
control operation, the analogue inputs remain active
(added to the serial setpoint).
(2) Motor potentiometer setpoints via digital inputs
are stored when P011 = 1.
