2.3 Intended use
The microspeed® uni motor system is a universal system with respect to
its range of applications and to the system composition and its variety of
uses.
The microspeed® uni motor system is used in orthopedics/traumatology,
neurosurgery, spine surgery, hand/foot surgery, ENT/OMF surgery, plastic
surgery and arthroscopy.
The microspeed® uni motor system can be operated as complete from the
sterile area, either through foot control or through hand control.
2.4 Mode of operation
The microspeed® uni motor system comprises the following components:
• Control unit with coolant pump, for universal application
• Two motor cables (with or without hand control)
• Various motors with different coupling types
• Pistol handpiece
• Shaver handpiece
• Two foot control devices
2.4.1 Control unit
Control unit 1has been designed for a mains voltage rating of 100 V to
240 V/50 Hz to 60 Hz. The mains voltage is transformed so that the motors
run at safety low voltage.
Control unit 1is equipped with two motor connection sockets 5for
connecting two (different) motors, and with one foot control connection
socket 14 (on rear panel).
The following devices can be connected to control unit 1at the same time:
•Twomotorsand
• One foot control (GD668 or GD671).
Note
Do not connect two shaver handpieces GD682 at the same time.
Only one motor can be activated at any one time.
Motors with motor-side plug connection (GD674, GD676, GD677, GD678
and GD679) can be operated either through hand control (motor cable
GD673) or foot control GD668 or GD671 (with motor cable GD672).
Note
When two motors without hand control are connected to the control unit
(motor cable GD672), a motor can only be activated if the motor release
switch of the motor that is to be activated is in the “ON” position while the
other motor is locked (motor release switch in “OFF” position).
2.4.2 Control and display interface
Display 2shows the present device status (operating and error conditions)
at all times. The display is divided into motor control field(s) and a pump
control field. The device parameter settings can be changed by pressing
the control keys.
For information on all the symbols used in the motor and pump control
fields, see chapter Symbols in display.

In this program the maximum motor speed is limited to 16,000 1/min. The
settings most recently used with the saw program (motor speed range
upper limit, dose level for coolant pump 4) are recalled automatically.
2.4.8 Automatic saving of device settings
The most recent settings for this motor type at this motor connection
socket (speed range upper limit, delivery rate, etc.), are called up
automatically as soon as the same motor type is recognized again as
connected at the same motor connection socket of control unit 1after a
motor change.
Note
After each device start-up both the coolant pump and motor type-specific
special functions such as the saw program (for GD678 and GD679) or the
oscillating or tapping mode (for GD684) are always inactive (even if they
had been released or activated before). All parameters are reset when the
operating key "Factory setting" in the Instruction menu is pressed.

2.4.9 Overload cut-out
To protect the connected motors against thermal destruction, the system
features a separate motor temperature monitoring device. For this
purpose, a temperature module is integrated in the device.
•1stLevel:
As soon as the temperature module indicates a motor temperature
above 75 °C and below 90 °C, an acoustic warning is sounded and the
message “Temp. Motor” flashes on the display. Any further overload
causes control unit 1to switch to level 2.
• 2nd Level:
As soon as a motor temperature in excess of 90 °C is detected, the
motor is switched off and the message “Error 7 – Motor overheated” is
shown on display 2.
After a cooling-down period the motor can be activated again.
Alternatively, the temperature module is reset, and work can be continued
as soon as the overheated motor has been replaced. We recommend
keeping a replacement motor on standby.
2.4.10 Coolant pump
Note
The coolant pump only works when a motor is running!
At power-on of the control unit, coolant pump 4 is always deactivated
(even if it had been released for operation at an earlier time).
The microspeed® uni control unit 1is fitted with a coolant pump 4. This
coolant pump serves exclusively for cooling or irrigating the tools. The
delivery rate at the highest dose level is approx. 80 ml per minute. The
coolant pump can be activated either in the respective motor control field
or through the appropriate hand or foot control device. The delivery rate
can be selected via the pump control field or through the Device settings
menu, see chapter Submenu Device-specific settings.
Exception: When using pistol handpiece GD684, the pump can be
activated, and the delivery rate can be changed, only via the appropriate
control fields on the control unit.
Any one of 21 dosage settings can be selected. At dosage settings 1 to 5,
coolant pump 4operates in intermittent mode. The pump can be switched
on and off, and the delivery rate can be changed, even while the motor is
active. Once the motor was active for more than two seconds, a special
drive control prevents further coolant from dripping out.
2.4.11 Motor cable
Note
A motor cable is needed to connect motors (with motor-side plug
connection) GD674, GD676, GD677, GD678 and GD679 to the control unit.
The microspeed® uni motor system comprises one motor cable for foot
control (GD672) and one motor cable with hand control (GD673). Both
motor cables can be used in connection with all motors with a motor-side
plug connection. Either of the two motor cables can be connected at any
of the two motor connection sockets 5.
Notes
The choice of motor cable depends on the application and which handpiece
is to be used.
For using saws GB128R, GB129, GB130R and motor cable with hand
control GD673, we recommend guiding the saw with both hands for
optimal handling. If single-handed saw guidance is required, use motor
cable GD672 with a foot control device.
WARNING
Risk of injury due to uncontrolled movement of skin
abrading handpiece GB280 in conjunction with a motor
cable with hand control GD673!
¾Use skin abrading handpiece GB280 only with motor
cable GD672 and foot control.

2.4.12 Motors
Motors with motor-side plug connection
Note
A motor cable GD672 or GD673 is required for connecting motors with
motor-side plug connection to the control unit!
Depending on the field of application, there are five different motor types
available, with the three Aesculap standard coupling systems Hi-Line,
micro-Line (Intra coupling system to DIN 13940/ISO 3964) and mini-Line.
Each motor can be operated in right or left (clockwise or
counterclockwise) rotation mode. When a motor is running in left-
rotation mode, control unit 1issues an acoustic signal.
For the performance data and parameters to be set for the individual
motor types, see chapter Technical specifications.
Motor types GD678 and GD679 offer the option to select a saw program.
In this program the maximum motor speed is limited to 16,000 1/min.
Motors with fixed motor cable GD682 and GD684
Note
The motors are directly connected to the control unit. An additional motor
cable is not required!

protect against injury and damage when inserting Kirschner wires.
There are two operating modes of pistol handpiece GD684:
• Standard operation
• Oscillating or tapping mode
If control unit 1recognizes a pistol handpiece GD684 connected, the
pistol handpiece will operate in the Standard mode (factory setting). The
device parameter settings (speed range upper limit, delivery rate, pump
status) can be changed only via the touch control field of control unit 1.
Oscillating or tapping mode can be selected via the Instruction menu. The
symbol for “Oscillating or tapping mode” is displayed in the respective
motor control field. Oscillating or tapping mode is activated though the
upper trigger. An acoustic notification signal is sounded and “Oscillating
or tapping mode active” flashes in the respective motor control field. In
this mode of operation, the speed range upper limit cannot be changed via
the touch control field on control unit 1.
The oscillating or tapping mode can be deactivated again by pressing the
upper trigger. After each power-up of the control unit and connection of
the pistol handpiece, oscillating or tapping mode is always deactivated
and needs to be activated anew via the pistol handpice. The preselected

holding upper trigger 34 for three seconds.
Working in “Oscillating or tapping mode”:
• The pistol handpiece is operated in tapping mode by pressing lower
trigger 35 within the first half of the total trigger travel. The motor
speed is proportional to the actual trigger travel.
Tapping mode means: Clockwise rotation by a certain angle (forward step)
followed by counterclockwise rotation (backward step) by a smaller angle.
• The pistol handpiece is operated in oscillating mode by pressing lower
trigger 35 within the second half of the total trigger travel. The motor
speed is proportional to the actual trigger travel.
Oscillating mode means: Clockwise rotation by a certain angle followed by
counterclockwise rotation by the same angle.
