1.0 General
The control unit generates an adjustable output frequency for the vibratory feeder independently of the
mains frequency. The PFC circuit on the input side ensures a constant output voltage both at an input
voltage of 110 V and 230 V.
Mains voltage fluctuations have no influence on the feed rate. In addition, the operating mode “Amplitude
control" combined with an accelerometer enables a constant feed rate even with changing feeder loads.
In this operating mode, the feeder's resonant frequency can also be determined and the output frequency
for the feeder continuously tracked.
An integrated track control enables a backlog circuit to be set up for material control via a PNP distance
sensor.
For the operation of a blowing air valve, a 24 VDC output is available in the IP54 housing version.
The unit is operated via an LC display and programming buttons. All the settings can be done using this
display without opening the housing.
Special features:
•Output voltage up to 205 VAC, independent of
mains supply.
•Mains frequency independent, adjustable
output frequency
•Min and max limits of the frequency range
adjustable
•Adjustable current limit for maximum coil
current
•Constant feed rate in the event of mains
fluctuations
•Control of the resonant frequency
•Status relay On / Off
•Ready relay (IP20 only)
•Track control
•24 VDC Output for e.g. air valve (IP54 only)
•Four application-specific parameter sets can
be stored
•With option "Interface operation via field bus"
•Thermal switch input for coil temperature
monitoring
2.0 Function
The controller generates an adjustable output voltage with an adjustable output frequency that is
independent of the mains supply. The input-side PFC circuit ensures a constant output voltage at an input
voltage of 99 V to 264 V. The output voltage is changed to control the feed rate. The output can be
switched on or off via the keyboard or an enable input by a higher-level external control unit. After
switching on the unit, the output is ramped up over an adjustable time ramp (soft start) or ramped down
after switching off (soft stop). The unit can be operated in a manual mode at constant output frequency or
in controller mode with amplitude control and frequency control. For controller mode an acceleration
sensor e.g. SW10 is required, which is mounted on the vibrating part of the feeder. This sensor detects
the feeder's vibration movement and reports this actual value back to the internal controller. In this
operating mode, in addition to the amplitude control, the feeder's resonant frequency is determined and
adjusted accordingly with different loads, so that a constant flow of parts results with an optimum vibrating
frequency of the feeder. The setpoint for the feed rate is specified as standard via the internal display but
can also be supplied externally by means of a 0...10 V or 0/4...20 mA DC signal. For feed rate control, an
integrated track control allows the realisation of a material flow control. This function requires an external
24 V PNP distance sensor to detect the conveyed parts. This creates a defined material flow via
adjustable time stages for switch-on and switch-off delay. The "time out" function can be used to monitor

whether parts pass the sensor within a period of time (e.g. no-load signal). As an alternative to the
material flow control, the sensor input can be used for switching to a second, internally adjustable
setpoint, e.g. to realise a "fast/slow" function. In parallel with control of the feeder, a 24 V DC output is
available for the IP54 housing version, which can control a blowing air valve to support the parts flow.
This output can switch on before the feeder starts and switch off with a time delay after the feeder has
switched off. The time delays are adjustable. Depending on the conveyor, the nominal unit current can be
set between 5% and 100%. If the current limit is reached, the output voltage is reduced so that the current
limit is not exceeded. Sensitive settings such as current limit and frequency limits are combined in a limit
menu. Settings in the menu can only be made after enabling the key number in the "Service menu". In the
service menu, the current settings can also be saved and the factory settings of the units can be restored.
2.1 Track control
Via internal, adjustable
time steps ("t on" and "t
off"), the output is
switched ON or OFF
depending on the
material level measured
via a track component
sensor. The level of the
conveyed material thus
varies around the
position of the track component sensor installed on the feeder. The output of the control unit is switched
on when the conveyed material falls below the sensor and the set switch-on time delay has elapsed. If the
conveyed material exceeds the position of the sensor, the control unit's output is switched off after expiry
of the switch-off delay (indication in the display: " full"). Gaps in the flow of conveyed material reset
the time stages. The times are always determined by the last or first conveyed part.
The switch-on or switch-off delay time is set in the programming menu. The run-down of the internal time
stages is shown by the clock in the display.
When the feeder is switched on, a further time stage "sensor timeout" can be started, which switches
the feeder off after an adjustable time (1...240 sec.) if no material parts have passed the sensor within this
time. When the feeder is switched off, the status relay also switches off. The display then shows "Track
Timeout and Info 0001" flashing alternately. This function is optional and must be activated in the track
control menu with function "Timeout On" = .
2.2 Operation with two speeds (2
nd
setpoint for coarse/fine switching)
Instead of track control, coarse/fine operation can also be used. Switching to the second setpoint is done
via the sensor input that is otherwise used for track control. Switching can be done with a contact or an
external 24 VDC signal voltage. If a 24 V signal is present, the system switches to the second setpoint
"Fine" without any time delay.
(The track control function is not available.)

4.3 Temperature of protective housing
Only suitable for mounting on concrete or other non-combustible surfaces.
4.4 Coolant type
Free convection.
4.5 Current consumption
The current consumption specified in the technical data is the maximum permissible value for the unit. A
higher current consumption than specified can lead to malfunctions and failure. Please note that the input
current is inversely proportional to the input voltage. When the input voltage is high, the input current is
low and when the input voltage is low, the input current is high.
Example:
A 230 V vibratory feeder is operated on a 230 V mains supply using the MFS368. A current of 1 A is
detected at the input of the controller. The same 230 V vibratory feeder is then operated on a 110 V
mains supply. The input voltage is only half as high as before and the input current is therefore twice as
high. This means that the input current of the controller on the 110 V mains supply is then 2 A.
NOTE: When dimensioning, especially for international markets, ensure that the maximum specified input
current is not exceeded at the lowest expected supply voltage.
4.6 Warning signs
Warning sign "Warning of too hot surface" must be visibly attached to the heat
sink.

8.1 Preparatory measures
Notes
With the control units described here, it is possible to adjust the resonant frequency of
the connected feeder. Since in this case even a small setpoint value can lead to full
operation of the feeder, appropriate care must be taken to ensure that no damage
occurs in the feeder due to coil hammering.
In practice, however, the resonant frequency range cannot be used without feedback of
the acceleration, as the feeder would not be loadable or controllable. Therefore, a certain frequency offset
from the resonant frequency must be set. The frequency offset can be both below and above the
resonant frequency.
Independent of the input voltage, the frequency converter's output voltage is 205 VAC
when delivered. When using 110V VAC coils, the output voltage must be set using
parameter: "Umax", otherwise the feeder coil and the drive or the vibratory feeder may
be damaged.
•Check whether the local supply voltage corresponds to that of the unit (type plate information) and
whether the connected power of the feeder is within the permissible power range.
•Check that the output voltage and frequency of the control unit are compatible with the selected
magnet.
•Connect the control unit according to the enclosed connection diagram
•Adjust setpoint to zero
•Switch off Enable (if used)
The control unit is now basically ready for operation and can be switched on (mains, Enable).
Resonance frequencies: Due to the structure of the spring-mass system of the feeders, the system can
resonate at several vibrating frequencies. The additional resonant points are at a multiple of the desired
frequency. In critical cases, the automatic frequency search cannot reliably detect the desired vibrating
frequency; in this case, the frequency may have to be adjusted manually.
Storage: After a storage period of one year, the internal DC link capacitors must be reformed. To do this,
connect the MFS to the supply voltage for 60 minutes without load; for the IP54 version, also switch on
the mains switch. If the product is stored for more than one year, the manufacturer must take care of the
reforming. Failure to observe the reforming prescriptions may result in the destruction of the unit.
8.2 Operating frequency of the feeder coils
When using the unit for the first time the current in the solenoid circuit should be
checked with an RMS meter or the heat development at the coil should be monitored,
as the current through the coil may increase at low frequency settings.
In order to avoid excessive power consumption and thus possibly an overload of the coils, please make
sure that the coils are designed for the operating frequency.
An incorrect vibrating frequency may lead to the destruction of the coils and the drive or the vibratory
feeder. Make sure that suitable feeder coils are used for the desired vibrating frequency.
8.3 Measurement of output voltage and output current
Since the unit output is an electronic frequency converter with pulse-width modulated switching signals,
the voltage and current values cannot be measured with any standard measuring device. Moving iron
meters are recommended for measuring these values.

9.1 Notes on controller mode
•For controller mode, an accelerometer mounted on the vibratory feeder is required, e.g. SW 70 (for
IP54 units) or SW10 (for IP20 units).
•In control mode with sensor feedback, all vibrations detected by the sensor are processed in the
control circuit. External vibrations caused by neighbouring machines, by an unstable position of the
feeder, or by unstable mounting of the accelerometer can lead to erroneous control performance.
Especially during the AFS automatic frequency search, no external influences must be allowed to
affect the feeder.
9.2 Mounting the accelerometer
The accelerometer must return the movement and the acceleration of the feeder to the control circuit of
the control unit. It is therefore very important that no additional spurious vibrations caused by an
unfavourable sensor mounting are measured.
The sensor should be mounted in the direction of
vibration (ideally at the same inclination as the
feeder springs) on a solid mounting block which
does not generate any natural vibrations.
The accelerometer cable must be supported with a cable clamp to prevent the cable
from being damaged.
In control mode, the output signal level directly determines the feeder's maximum vibration
amplitude.

In the case of bowl feeders, it is advisable to mount the sensor as
far as possible on the outer diameter so that the largest possible
vibration displacement is covered.
If the sensor signal is too low, the setpoint's control range is
significantly restricted.
s = vibration displacement
Mounting point 1 = small vibration amplitude
Mounting point 2 = large vibration amplitude
Example of bowl feeder
1. small amplitude with vertical
mounting.
2. larger amplitude when
mounted at the same
inclination angle as the
springs.
Example of linear feeder
The control system and the sensor attached to the feeder form a closed control loop, whereby the signal
supplied by the sensor has a decisive influence on the setpoint's control range. I.e. the feeder is
controlled so that the actual value (feed rate or vibration intensity) corresponds to the specified setpoint
(ideal: 100 % setpoint = 100 % actual value). However, since the actual value depends on the feeder
(frequency, acceleration, vibration amplitude) and also on the sensor's mounting location, the control
range must usually be adjusted.
The adjustment is made with the "Max" parameter in the "Feeder" menu. The measured sensor signal is
adjusted with the value that can be set here. In most cases, a value below 100 must be entered so that
the setpoint’s control range reaches 100 % or appears to be as large as possible.
If no satisfactory adjustment is possible, the accelerometer should be mounted at a location with a larger
vibration amplitude (see example of bowl feeder).
The importance of adjusting this value can be seen, for example, in the time response of the controller.
Where the actual value is badly adjusted, for example, the result can be that the feeder only ramps up
very slowly when it is switched on.
