COMMON PARAMETERS DESCRIPTION
Basic Function
F02: Run Command
This function code defines the way in what the “RUN” signal will be given to the inverter in order to start
the pressure control.
Usually, “Run Command” is sent to the inverter by means of the digital input (F02 = 1). That is, switching
on FWD or REV (control terminals in the inverter) digital inputs enables the inverter output.
A RUN command can be also activated by means of the keypad, pushing FWD or REV buttons (in TP-G1
keypad) or RUN in basic keypad (TP-E1).
F07: Acceleration Time 1
F08: Deceleration Time 1
These acceleration/deceleration ramps are used in two cases:
1. After the Run Command is ON, F07 ramp is used to achieve the frequency in J43 or J19 (the
biggest one of both values).
When the Run Command is switched OFF, F08 value defines the deceleration ramp to go from the
current frequency to the stop frequency (F25).
2. These ramps are also used when the inverter is connected/disconnected from the commercial
power supply if function codes J39 and J40 are set to 0.00 (please refer to the corresponding
diagrams in the following chapters).
F11: Electronic Thermal Overload Protection. Overload detection level
F12: Electronic Thermal Overload Protection. Thermal time constant
By means of these two parameters is possible to adjust the overload protection function. Normally, F11
will be adjusted to the motor’s rated current and F12 to 5 minutes.
F15: Frequency Limiter. High
F16: Frequency Limiter. Low
These two parameters define the frequency limits, and the inverter will never go outside of these limits
during pump control.
It’s normal to adjust the parameters F15, J18 and F03 with the same value.
Equally, F16 should be equal to J19, too.
Inputs Set-up
E62: Analog Input for [C1]
This parameter can be used to select the function for analog input C1.
Usually this parameter is set to E62 = 5, this setting will define the [C1] analog input as PID Feedback
(pressure transducer).
Motor Map
P01: Motor. Number of poles
P02: Motor. Rated Capacity
P03: Motor. Rated Current
In these parameters must be stored the number of poles, rated capacity and rated current as are shown in
the motor’s nameplate.
