Parameter Function Range

[Default]

Description / Notes

P007

Keypad control 0 - 1

[0]

0 = The RUN, REVERSE and JOG buttons are disabled. Control is

via digital inputs (see parameters P051 - P053). ∆ 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 = OPm2 buttons are enabled (can be individually disabled

depending on the setting of parameters P121 - P124). The

digital inputs for RUN, JOG and ∆ / ∇ 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.

P011

Frequency setpoint memory 0 - 1

[0]

0 = Disabled

1 = Enabled. The setpoint alterations made with the ∆ / ∇ buttons or

digital inputs are stored even when power has been removed

from the inverter.

P012 •

••

•

Minimum motor frequency (Hz) 0 - 120.00

[0.00]

Sets the minimum motor frequency (must be less than the value of

P013).

P013 •

••

•

Maximum motor frequency (Hz) 0 - 120.00

[50.00]

Sets the maximum motor frequency.

P014 •

••

•

Skip frequency 1 (Hz) 0 - 120.00

[0.00]

A skip frequency can be set with this parameter to avoid the effects of

mechanical resonance. Frequencies within +/-(value of P019) of this

setting are suppressed. Stationary operation is not possible within the

suppressed frequency range - the range is just passed through.

P015 •

••

•

Automatic restart after mains

failure.

0 - 1

[0]

Setting this parameter to ‘1’ enables the inverter to restart

automatically after a mains break or ‘brownout’, provided the run/stop

switch is still closed or the link is fitted, P007 = 0 and P910 = 0, 2 or 4.

0 = Disabled

1 = Automatic restart

P016 •

••

•

Start on the fly 0 - 2

[0]

Allows the inverter to start onto a spinning motor.

Under normal circumstances the inverter runs the motor up from 0 Hz.

However, if the motor is still spinning or is being driven by the load, it will

undergo braking before running back up to the setpoint - this can cause an

overvoltage trip. By using a flying restart, the inverter ramps up the output

voltage at the setpoint for the period defined by P020.

0 = Normal restart

1 = Flying restart after power up, fault or OFF2 ( if P018 = 1).

2 = Flying restart every time (useful in circumstances where the

motor can be driven by the load).

P017 •

••

•

Smoothing type 1 - 2

[1]

1 = Continuous smoothing (as defined by P004).

2 = Discontinuous smoothing. This provides a fast unsmoothed

response to STOP commands and requests to reduce frequency.

Note: P004 must be set to a value > 0.0 for this parameter to have

any effect.
