1. Int oduction
Depending on its construction, the speed of a three-phase a.c. motor is directly dependent
on the number of poles and the frequency of the network. In a 3ph 380 /50Hz network,
with a 2-pole motor, the rated speed would be 50 U/s * 60 = 3000 Upm.
With d.c. motors (brushless d.c.), the speed is dependent on the voltage applied
Three-phase a.c. motors provide numerous benefits in industry, such as brushless operation,
freedom from wear and tear, favourable capacity/weight ratio, high-speed capability, and
much more. These motors can be used many different application areas, such as milling and
grinding spindles, or with drilling machinery, for example.
D.C. motors have the advantage of a high power efficiency (approx. 85%) when compared
with a.c. motors, but the disadvantage of not quite reaching the torque of an a.c. motor at
low speeds (when starting), nor reaching the high speeds of an a.c. motor. However, the
higher efficiency also means cooling requirements are lower and dimensions can be smaller.
In the aforementioned applications, three-phase a.c. motors are operated using special
control gear – frequency converters. These frequency converters convert the fixed 50 Hz
network into a 3-phase network with variable frequency and voltage. This greatly reduces
the start-up problems and the high starting currents that are inevitable when high-capacity
three-phase a.c. motors are connected to a fixed network. The motor is controlled according
to a special characteristic curve until its rated speed has increased, or it has been stopped.
The SFU 0102/0202 - series frequency converter has been specially designed for use in these
high frequency applications, offering excellent safety, performance and reliability, the result
of years of experience in the design and construction of frequency converters, together with
the use of the latest materials and the most reliable components. It can be used in many
different applications and is as equally suitable for use as a replacement device in existing
systems with older type series as it is in pre-planned applications as a cost-effective solution,
helping to prolong the useful life of tools. In addition, both a.c. and brushless dc motors can
be operated by this high frequency converter.


Automatic control and configuration via PC (RS232 interface)
Setup and control of the features and functions listed below can be carried out with our setup
software SFU-Terminal. All explanations and hints to menu functions relate to this software.
7.1 Configu ation of otational speed
The preset of revolutions per minute of the spindle can be achieved by two ways:


 P eset manually via panel keys
In menu 'Analogue Inputs' option button 0 has to be enabled in the line of duty RPM . (no analogue
input is assigned to this function)
The duty RPM is displayed on the LCD and can be changed with UP / DOWN (holding a key down
increases the count rate). RPM can be changed during operation


 P eset via analogue input duty RPM
In menu 'Analogue Inputs' option button 0 has to be disabled and the function duty RPM . has to
be assigned to an analogue input. Additionally a scaling has to be selected from the list box duty RPM
(e.g.: 1 /10.000RPM)
The value of the duty RPM is displayed on the LCD according to the scaling and the voltage at the
input. A voltage of 0 leads to a standstill and a voltage higher than 0 leads to a startup upto the
desired revolution. An input voltage of 4 and a scaling as above mentioned lead to a revolution of
40.000 rpm.
The settings have to be downloaded into the converter with the button write data.
CAUTION: The ope ation of a spindle with a w ong spindle cha acte istic
may cause seve e damages at spindle o conve te .
To avoid this, please ensu e that the co ect spindle

7.2 Sta ting and Stopping the F equency Conve te
There are different methods of starting and stopping SFU 0102/0202 frequency converters,
due to many different requirements, as follows below:


manually via panel keys


Remote control via digital input


Remote control via analogue input


Remote control via serial interface
Before starting the converter is possible, a preset of the RPM (> 7.4) has to be done. This is
necessary for all options of starting with the exception of analogue starting.


Manually via panel keys
Activation of spindle start via the green START key.
Spindle-stop is activated by the red STOP key on the operator panel.


Remote control via digital input Start/Stop by external PLC or CNC
Digital Input 1 is the default. To change this, click on the menu ‘digital inputs’. The correct
spindle characteristic can be preset here also.
Depending on your safety regulations, you can program this individually and set high or low
active signals. In general, when using SPS control, it is best to set safety cut-outs at low-
active, so that the machine will stop should a cable or connector defect occurs.


Remotely via the analogue input
Analogue starting will be enabled where at least one of the analogue inputs in the menu
'analogue inputs' is selected and a valid signal at the digital input Start/Stop is present.
Additionally a scaling has to be selected from list-box duty RPM of analogue value to RPM.


Remotely via the RS232 serial interface from a PC or PLC .
The speed pre-selected from the panel is taken as the required speed in this instance. Speed
can be altered via commands from the RS232 interface.
The RS232 interface offers complete control of the SFU 0102/0202 converter via the optional
full- version Windows platform. The level of control this provides is almost at machine-level,
so that this option is more appropriate for error evaluation and special control features via PC.
If you need to control the SFU 0102/0202 remotely, please contact BMR or your local
distributor for assistance and the RS232 command-set.
Whe e one of the above options has been selected to ope ate the conve te ,
only that p eselected option can then be used to stop the conve te ! Only
one of the safety functions can o
ve ide the ope ation.

ia digital input RPM direction . Setup is carried out in menu ‘digital inputs’. This is necessary,
if the direction of rotation has to be controlled , for example, via a PLC. Reversal can only take
place once the spindle / motor has come to a complete stop. If the direction pre-selection
setting is changed whilst the spindle / motor is running, the spindle / motor will not turn in
the new direction until it has been brought to a complete standstill and then restarted.
7.4 Safety stop functions
As shown above, all these safety and start-up features are programmable and a digital input
pin or logical behaviour of this pin (high-, low-active) can be selected.
The following safety functions bring about controlled stopping of the machine, pre-defined
by the deceleration times selected within the spindle characteristics,

The remote control of the converter is connected via the 15-poles SUB-D-JACK (13).
The display (2.4) is on whenever the converter is remote controlled.
POSSIBILITIES OF REMOTE CONTROLLING:
a) Digitally: With a Start/Stop (0 / +24 ) signal at digital input1/ Pin12 .
The input can be setup to be Low- or Hi-active. The value of rotational speed can be preset with the
Potentiometer or with a DC-voltage at Pin11-8
b) Analogue: with a DC voltage at the analogue input. Connect (+) to Pin11 and (-) to Pin 8 (GND)
Precondition is a valid Start signal at Pin12
Uin < 0,5 is Spindle "Standstill" and Uin ≥ 0,5 is Spindle "ON".
Equally herewith the rotational speed is controlled according to the scaling of speed to analogue value.
Possible is 1 /10.000rpM or 0-10 min/max.
c) RS232: with control commands via serial interface Pin13 (RxD), Pin14 (TxD) and Pin8 (GND)
A list of commands is available seperately on request.
ATTENTION: The DC voltage at Pin11 must not excced 12 and should be free from ripple
voltages
ATTENTION: This evaluation is only possible if the spindle is equipped with a
temperature sensor. (Option after arrangements)
If a Start is initiated by one of the above mentioned start operating modes, a subsequent
stop is accepted in the same mode only. This is valid not for safety functions
Tipp: It is ecommended to usw a shielded cable

Rotational Speed Reached
If the spindle reaches the preset value of the rotational speed, one of the two halves of
display (3.3) flashes.
The left half with the symbol „desired value“ flashes if the internal frequency of the converter
corresponds to the adjusted frequency.
This evaluation happens whenever the spindle is not equipped with a magneto resistor.
The right half of the symbol „actual value“ flashes if the spindle axle reached the adjusted
rotational-speed in fact (actual evaluation).
Standstill of Spindle
The display (3.4) flashes whenever the spindle axle stands still.
The converter considers two possibilities of the evaluation:
a) if the spindle is not equipped with a magneto resistor the symbol flashes when the converter
stopped giving more frequency (standstill of converter)
b) if the spindle is equipped with a magneto resistor the symbol flashes not before the spindle-
axle is standing still.

Eme gency Shutdown Inte lock
The emergency shutdown interlock can be programmed by software „active“ or „inactive“.
Programming „inactive“ is insignificant, whereas with a „active“ programming a primary stop-
command can be given. This means that the converter cannot be started again neither by
the „Start-button“ nor by the remote-control and that the spindle will be controlled slowed
down.
To abolish the command „shutdown-interlock“ there has to be applied a voltage of 5 ...30
on the control connector (13)
