MENU 2 CHANGING VIBRATION AMPLITUDE
CFF DCFF CFV
This menu allows you to vary the required acceleration or power supply to the vibrator according to the
modes selected in Menu 1.
If we have selected in Menu 1:
Tracking Mode (Mod.1) with SRV02 probe: The parameter is “A0” and it is the acceleration the vibrator
requires expressed in g (g = 9,8 m/s²). The minimum value is 0.0, the maximum value is 99.9. (Obviously
each vibrator will have a maximum threshold which depends on its mechanical structure).
Tracking Mode (Mod.1) without SRV02 probe: The parameter is “A0” and it is a number representing the
power delivered to the vibrator. The minimum value is 0.0, the maximum value is 10.0.
Variation Mode (Mod.0) with SRV02 probe: The parameter is “VI” and it is the power delivered to the
vibrator. The minimum value is 0.0, the maximum value is 100.
Variation Mode (Mod.0) without SRV02 probe: The parameter is “VI” and it is the power delivered to the
vibrator. The minimum value is 0.0, the maximum value is 100.
MENU 3 CHANGING FREQUENCY
CFF DCFF
This menu allows you to set vibrator frequency.
Settable frequencies are: 33 Hz, 50 Hz, 100 Hz.
The set frequency must be the same at that shown on the vibrator data plate.
The set frequency must be the same as the vibrator control frequency. In order to know the vibrator
frequency, just read the identification plate in the space given to the vibrator model code. If you find
the code DC (3000 vibrations per minute) then you will have to set F. 50 on the controller. If you find
AC (6000 vibrations per minute) you will set F. 100 on the controller.
ATTENTION: Running a vibrator with 100 Hz coil at a lower frequency may permanently damage the
vibrator.
CFV
This menu allows you to change vibrator frequency.
The frequency range is from 10 Hz to 140 Hz.
To operate correctly, the frequency set in manual mode must be close to the frequency written on the
vibrator data plate.
The set frequency must be the same as the vibrator control frequency. In order to know the vibrator
frequency, just read the identification plate in the space given to the vibrator model code. If you find
the code DC (3000 vibrations per minute) then you will have to set the frequency next to F. 50 on the
controller. If you find AC (6000 vibrations per minute) you will set the frequency next to F. 100 on the
controller.
ATTENTION: Running a vibrator with 100 Hz coil at much lower frequencies may permanently damage the
vibrator. If you want to change frequency, constantly check the current absorbed by the vibrator coil.
MENU 4 CALIBRATED TRACKING
CFF DCFF
Menu disabled for these controllers.
CFV
The Calibrated Tracking function can only be set if the SRV02 probe is present and if automatic Calibration
(menu 14) has been fully performed. The Tracking function (Mod. 1) must also be set in Menu 81. To use
this function set parameter C2 to 1.
If you use this operating mode an automatic procedure is enabled which implements the “A0” acceleration
value using variations in delivered power and variations in working frequency. The frequency range used is
calculated during the automatic calibration stage and is compatible with the vibrator structure.
Due to mechanical wear and tear of the structure or springs in the vibrator, the calculated frequency range
may sometimes no longer be sufficient to obtain the set acceleration value from the vibrator. To solve this
problem, simply set parameter AC2 to 1 from Menu 4. With this option, if the controller encounters difficulty in
maintaining the set acceleration it automatically recalibrates and calculates the new optimal parameters so
that it operates correctly.
