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.

= 15 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.

Sets the frequency that the inverter will run at when operated in digital mode. Only effective if P006 set to ‘0’.
Sets the control mode of the inverter.
0 = Digital. The inverter runs at the frequency set in P005. Alternatively, if P007 is set to zero, the frequency may be controlled by setting any two of binary inputs P051 - P053 to values of 11 and 12.
1 = Analogue. Control via analogue input signal.
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.
(2)Motor potentiometer setpoints via digital inputs are stored when P011 = 1.
0 = Front panel buttons disabled (except STOP, Δ and ∇). Control is via digital inputs (see parameters P051 - P053). Δ and ∇ may still be used to control frequency provided that P124 = 1 and a digital input has not been selected to perform this function.
1 = Front panel buttons enabled (can be individually disabled depending on the setting of parameters P121 - P124).
Note: The digital inputs for RUN, REVERSE, JOG and increase/ decrease frequency are disabled.
P009 ∙
Parameter protection setting | 0 - 3 |
| [0] |
Determines which parameters can be adjusted:
0 = Only parameters from P001 to P009 can be read/set.
1 = Parameters from P001 to P009 can be set and all other parameters can only be read.
2 = All parameters can be read/set but P009 automatically resets to 0 when power is removed.
3 = All parameters can be read/set.
