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.
