1. Safety notes
The described devices are electrical equipment for use in industrial electrical power
installations. An impermissible removal of the covers during operation can cause
serious damage to your health, since these devices contain live parts with high
voltages.
Adjustment work may only be performed by trained staff observing the safety regulations.
Assembly and mounting work may only be carried out with the equipment deenergized.
Make sure that all drive components are properly earthed.
Please read these commissioning instructions carefully before putting the device into operation.
Besides, the user must ensure that the devices and associated components are fitted and
connected in accordance with the appliable local, legal and technical regulations. The VDE-
regulations VDE 0100, VDE 0110 (EN 60664), VDE 0160 (EN 50178) , VDE 0113 (EN 60204,
EN 61310),VDE 0660 (EN 50274) plus the appropriate regulations of the TÜV (Technical Control
Association) and the trade associations apply in Germany.
The user must ensure that the drive turns into a safe operating state following a device failure, in
the event of maloperation, or if the control unit has failed etc..
Caution: Even if the motor is at rest, it is not physically separated from the mains.
2. Conformity
In industrial linguistic usage the drive controllers of the type SGP 160-2.5/4/8P/16P are called
"devices", however, in the sense of the "device-safety-law", the "EMC-law" or the "EC-guideline
for machinery" they are not devices or machines ready for use or connection but they are compo-
nents. It is only possible to define their final function, when these components are integrated into
the design and construction of the user.
To be able to use the devices to their intended purpose, it requires power supply networks
according to DIN EN 50160 (IEC38).
The user takes the responsibility that the user’s design and construction comply with the appli-
cable legal provision.
The commissioning is strictly forbidden as long as the conformity of the final product with the
guidelines 2006/42/EC (Machinery directive) and 2006/95/EC (Low voltage directive) is not
proved.

3. General description
The electronic speed controllers SGP 160-2.5/4/8P/16P are used for the speed control of d.c.
shunt-wound motors with external and permanent excitation. A remarkable feature of these
controllers is the high speed stability, irrespective of fluctuations in temperature, voltage and load.
By means of the controllers SGP 160-2.5/4/8P/16P it is possible to make a variety of adjust
-
ments, such as minimum and maximum speed, ramp-up and ramp-down time, current limitation,
as well as I x R compensation. Since the controller is equipped with mains-potentialfree control
inputs, an external control is easily possible.Since the controller can be equipped with mains-
potential-free control inputs, an external control is easily possible.
4. Usage to the intended purpose
The devices of the SGP 160-2.5/4/8P/16P-series are electrical equipment that is used in indus-
trial electrical power installations. They are designed for the application in machines, in order to
control speed-variable drives with d.c. motors.

7. Functional description
Speed setpoint
The setpoint voltage is 0 ... 10VDC. The setpoint value can be generated either by means of the
potentiometer or externally. By connecting a 500 Ohm resistor in parallel to the setpoint input
terminals it is possible to feed in a setpoint current of 0...20mA. With the setpoint integrator it is
possible to realize an acceleration and deceleration time that is linear in time.
Speed controller
The speed controller is designed alternatively for tachometer control or armature voltage control
with adjustable I x R compensation.
Current controller
The current controller generates the control voltage for the pulse stage. If the current actual value
exceeds the adjusted current setpoint, the motor voltage will be reduced. Thus the motor and the
drive are not overloaded.
Pulse stage
The pulse stage generates the control pulses for the thyristors. Their length from the trigger point
to the next zero crossing of the voltage wave enables a safe operation of the device even under
highly inductive load.
Power unit
The power unit consists of a single-phase, half-controllable bridge circuit and an exciting-voltage
source. The circuit additionally includes measures to protect the power semiconductors against
overvoltage.

10. Parameter adjustments
10.1 Ramp-up and ramp-down times
With the trimmer tint (P2) the ramp-up and the ramp-down can be adjusted between 0 ... approx.
5sec. When the controller inhibit is actuated, the ramp-up integrator is reset.
10.2 Maximum speed
With the trimmer nmax (P3) max. armature voltage can be limited between 90 ... 180V.
10.3 Minimum speed
With the trimmer n
min (P4) the minimum speed can be limited to 0 ... 50% of the adjusted
maximum speed.
10.4 I x R compensation with armature voltage control
The compensation voltage is adjusted with the trimmer I x R (P1). The compensation increases if
the trimmer is turned clockwise. The adjustment is to be made when the motor has its normal
operating temperature. The drive is to be adjusted to approx. 50% of the nominal speed,
unloaded as far as possible, and the speed is to be measured.
Then load the drive and compensate the resulting speed drop with the trimmer P1. Afterwards
check the effects of the compensation at minimum and maximum speed and re-adjust if
necessary. Make sure that an over-compensation, i.e., a speed rise under load, is avoided at any
rate, as otherwise the drive becomes unstable. In the case of tachometer control the potentio-
meter P1 is set to left stop.
10.5 Current limitation Imax
As a rule, the current limitation is to be adjusted with the potentiometer Imax (P5) so that the
maximum current required for the start-up and acceleration is provided. In the case of gearmotors
make sure that the limit torque of the gearing is not exceeded by adjusting the limit current too
high.
10.6 Adapting the resistor R21 for tachometer control
When the controller is operated with a d.c. tachometer, it may be necessary to adapt the resistor
R21 accordingly (depending on the amount of the tachometer voltage at nominal speed).
Basically, only resistors with a loading capacity of 1 watt are to be used. The trimmer I x R is set to
left stop. The resistance value can be determined with the following formula.
UTacho = voltage value of the d.c. tachometer in volts per 1000 revolutions
nMotor = nominal speed of the motor at UArmature max.
The calculated resistance is to be inserted in k Ohm.
