1.6 General product information
The digital three-phase servo amplifier BAMOCAR-PG-D3-400/400, 700/250, 700/400 forms a 4-quadrant drive
unit together with the motor, driving and braking with energy feedback in both directions of rotation. Depending
on the installed parameter set, the amplifier is suitable for EC synchronous motors, AC asynchronous motors or DC
motors.
The drive concepts are characterised by different advantages and disadvantages.
The EC drive (synchronous motor) has the highest efficiency and the highest power per weight and volume. It is
maintenance-free and has high control dynamics. The disadvantage is the field weakening range, which is difficult
to control, and the high braking torque in the event of a motor short circuit.
The EC synchronous motor (brushless DC motor) in its electrical version is a synchronous motor with permanent
magnet rotor and three-phase stator.
The physical properties correspond to those of the DC motor, i.e. the current is proportional to the torque and the
voltage is proportional to the speed. The speed is controlled stably up to the current limit (max. torque). In case of
overload, the speed decreases at constant current.
Rectangular speed-torque characteristic.
Current, speed and position are measured exactly.
The rotating field frequency is not a controlled variable, it adjusts itself independently.
The motor voltages and motor currents are sinusoidal.
The AC drive (asynchronous motor) has the highest speed range due to the simple field weakening and it does not
generate a braking torque in the event of a motor short circuit. The disadvantage is the size and the poorer
efficiency. The controlled variable is the rotating field frequency, taking into account the motor-specific
parameters (field-oriented control). The motor voltages and motor currents are sinusoidal.
With both three-phase systems, no motor movement takes place if the rotating field is switched off or there is
power stage damage. The heat loss occurs mainly in the motor stator.
The DC drive (direct current motor) has the best synchronisation and a high control range. Emergency operation
can be achieved by directly connecting the battery voltage. Disadvantages are the carbon brushes and the heat
generation in the armature. The drive can rotate at high speed in the event of a power stage failure.
The current is proportional to the torque and the voltage is proportional to the speed.
Current, speed and position (bearing) are measured exactly. The speed is controlled stably up to the current limit
(max. torque). In case of overload, the speed decreases at constant current.
Rectangular speed-torque characteristic.
Field weakening is possible with externally excited motors.
BAMOCAR-PG-D3-xxx can be used as a position controller, torque or speed amplifier. The actual speed value is
generated from the encoder unit (resolver or other) or internally (sensorless). A large control range and high
control dynamics require an encoder system.
Warning / Caution:
For DC, AC and BL servo amplifiers fed from the DC mains, the energy feedback into the DC
link during braking operation must be taken into account.

Attention: Braking energy
The braking energy is fed back into the battery.
The battery must be able to absorb the braking energy.
If the battery is disconnected from the unit during braking operation
high DC link voltages can occur.
Pay special attention when operating on laboratory power supplies!
In DC networks, the network must absorb the braking energy without the voltage rising above the
permissible value. If this is not ensured, a ballast circuit must be used.
In the case of non-grounded systems (vehicles, boats, machines)
the insulation between the touchable parts and the HV voltages must be monitored with an
independent insulation monitor.

1.10 Details of the safety instructions
Machinery Directive
The vehicle, machine or plant manufacturer must prepare a hazard analysis for his product. He must
ensure that no unforeseeable movements can lead to personal injury or damage to property.
Qualified staff
Hardware
Qualified personnel are characterised by education and training for the use of electronic drive
technology. They know the standards and accident prevention regulations for drive technology and can
assess the application. Possible dangers are recognised.
The local regulations (IEC, VDE, VGB) are known to the qualified personnel and are taken into account.
Software
Qualified personnel for the software must be trained for the safe programming of the devices in the
machines and systems. Incorrect parameterisation can lead to unauthorised movements. The parameter
settings must be checked against incorrect operation. Careful acceptance tests are to be carried out
with a 4-eyes principle
Working environment
Incorrect handling of the units can lead to damage to property or personal injury.
Only operate the units when the unit is closed or the control cabinet is secured!
Unit covers must not be removed.
Work on electrical connections only in a de-energised state.
The battery voltage must be safely switched off.
The voltages and residual voltages (intermediate circuit) must be measured before working on the unit.
The maximum permissible voltage must be < 42 V.
High temperatures > 70 °C may occur.
Working environments may be hazardous for wearers of electronic medical devices.
(e.g. pacemakers) can be dangerous. A sufficient distance to these electrical parts must be maintained.
Stress
During transport and storage, the prescribed climatic conditions must be observed.
The units must not show any mechanical damage. Bent housing parts can damage the insulating
sections. Never install damaged units!
The units contain components that can be damaged by electrostatic discharge. The general
recommendations for handling ESD-components must be observed. Special attention must be paid to
highly insulating plastic foils and synthetic fibres.

The closed housings are resistant to most environmental influences.
Special attention should be paid to the connection plugs.
To prevent internal condensation, pressure equalisation valves with moisture protection are installed.
In case of oil mist or salt spray, the function of the valves may be impaired.
Internal condensation can also occur when the heat sink temperature is colder than the ambient
temperature.
Short-term occurrence of impermissible environmental conditions is not critical.
Ice formation can damage the seals.
Operation under water is not permitted.
Humidity
The function of the pressure equalisation valves is overloaded.
Increased humidity in conjunction with salty air can lead to corrosion of the
aluminium heat sink.

2Mechanical installation
2.1 Important notes
Check the unit for mechanical damage.
Only install faultless units.
Mounting only in de-energised state.
Disconnect the positive and negative battery terminals, disconnect the DC
mains.
Assembly only by trained specialist personnel.
The installation position is arbitrary for units with liquid cooler.
If the heat dissipation is too low, the unit switches off via its thermal monitoring.
Take the unit mounting holes from the dimensional drawing or the drilling plan,
do not mark off the unit.
Mount the filter and choke spatially close to the unit.
Contact the cable shields with the mounting surface.
Lay the power cables (battery and motor cables) separately from the signal cables.
Observe the minimum cable cross-section.
Safe earth connection from the enclosure to the ground level
(vehicle ground, control cabinet ground)
Shieldless cable ends as short as possible.
Use only specified plugs.
Use vibration-proof screw connections.
Attention:
Power connection cable from BAMOCAR to battery as short as possible.
Longer cables lead to dynamic voltage drops due to the cable impedance.
These stress the built-in capacitors and shorten the service life.
