2.3 - Read mode
- Connect the console to the VARMECA 20 RS 232 socket.
- Power up the VARMECA 20.
- On power-up, the console display is positioned on the 1st
parameter P01 F-MIN.
The 1st line of the display indicates the parameter
description.
The 2nd line indicates the parameter value and its unit of
measurement.
The
key scrolls through the parameters.
The key is used for scrolling in the opposite direction.
2.4 - Parameter setting mode
• Parameter modifications must be made with the
VARMECA 20 stopped (run command disabled).
To modify a setting, use the or keys to access the
parameter.
The
key is used to make the parameter to be modified
flash.
Modify the setting value with the
or keys.
As soon as the value differs from the value memorised, the
message M ? appears.
When the desired setting value has been reached, it can be
memorised using the
key.
M ? disappears from the display.
The
key is used to quit parameter-setting mode.

P03 F-MAX Maximum operating frequency 32 to 220Hz 32 to 100Hz 50 or 80Hz
P04 REF 10V/20mA Calibration of the 10V or 20mA max. reference 32 to 220Hz 32 to 100Hz 50 or 80Hz
P05 ACCEL RAMP
*
Acceleration ramp
Ramp value to switch from 0 to 50Hz 0 to 100s 0 to 40s 3s
Incrementation
In the standard configuration, terminals 9 and
10 must be connected together in order to
modify the value of the acceleration ramp. 1s 0.1s
P06 DECEL RAMP
*
Deceleration ramp
Ramp value to switch from 50 to 0Hz 0 to 100s 0 to 40s 3s
Incrementation
In the standard configuration, terminals 9 and
10 must be connected together in order to
modify the value of the deceleration ramp. 1s 0.1s
P07 STOP MODE
*
Stop mode
ramp, freewheel or
automatic
ramp or freewheel ramp
Freewheel = freewheel stop
ramp = stop following ramp
automatic = controlled deceleration
P08 UN-MOT
Voltage applied to the motor at frequency
0 to 480V 230 or 400V
base
P09 FN-MOT Base frequency of motor 50 to Fmax 50Hz
P10 CONTROL U/F
*
Selection of voltage/frequency ratio
constant or dynamic
constant = fixed U/F
Voltage P08 will be applied at the point of constant from
frequency P09 0.25 to 1.1Kw
dynamic = dynamic U/F dynamic from
The voltage adapts automatically to the 1.5 to 4Kw
motor load (position of mini dip switch
K3 = OFF)
