1.6 General product information
The digital 3-phase current servo amplifiers BAMOCAR-PG-D3-700/400-400 in combination with the motor
provide a 4-quadrant drive which can be used in both rotation directions for drive operations and brake operations
with energy feed-back. According to the installed parameter components the amplifiers are suitable for EC
synchronous motors, ac asynchronous motors, or dc motors.
The individual drive versions have different advantages and disadvantages.
The EC drive (synchronous motors) has the highest efficiency and performance per weight and volume and
provides a drive solution free of maintenance and with a wide dynamic control range. However, the high braking
torque in case of motor short-circuits is a disadvantage and it is also difficult to control the field weakening range.
From the electrical view, the EC synchronous motor (brushless dc motor) is a synchronous motor with a
permanent magnet rotor and a three-phase current stator.
The physical characteristics correspond to those of dc motors, i.e., the current is proportional to the torque and
the voltage is proportional to the speed. The speed is steadily controlled up to the current limit (max. torque). In
case of an overload the speed drops and the current remains constant.
The speed/torque characteristic is rectangular.
Current, speed, and position are precisely measured. The field frequency is not controllable, it is automatically
adjusted.
The motor voltages and the motor currents are sinusoidal.
The ac drive (asynchronous motors) has the widest speed range due to the single field weakening and there is no
braking torque in case of a motor circuit. However, the unit size and the worse efficiency is a disadvantage. The
rotating field frequency can be controlled in due consideration of the motor specific parameters (field-based
control). The motor voltages and motor currents are sinusoidal.
With both 3-phase current systems there will be no motor movement neither when the rotating field is switched
off nor in case of an output stage damage. Most of the heat losses are generated in the motor stator.
The dc drive (dc motor) has the most uniform running and a wide control range. It is possible to provide an
emergency operation by directly connecting the battery voltage. The carbon brushes and the heat development in
the armature are disadvantages. The drive may run at high speed in case of an output stage damage.
The current is proportional to the torque and the voltage is proportional to the speed.
Current, speed, and position are precisely measured. The speed is steadily controlled up to the current limit (max.
torque). In case of an overload the speed drops and the current remains constant. The speed/torque characteristic
is rectangular. Field weakening might occur with separately excited motors.
The BAMOCAR-PG-D3xx can be used as position amplifier or torque or speed amplifier.
The speed actual value is generated in the encoder unit (resolver or others) or internally generated (without
sensors). It is necessary to provide an encoder system for wide control ranges and high control dynamics.
Warning/Attention:
For dc, ac, or bl-servo amplifiers which are supplied via the dc mains, it must be checked
that the energy is fed back into the bus during brake operation.

Attention: Braking energy
The braking energy is fed to the battery.
The battery must absorb the braking energy.
If the battery is disconnected from the device during the braking process,
high bus circuit voltages might occur.
Pay particular attention when used with laboratory power supplies.
For dc mains the braking energy must be absorbed in the mains without the voltage exceeding the
permissible value. If this cannot be guaranteed, a ballast circuitry must be used.
For non-earthed systems (vehicles, boats, machines)
the isolation between parts accessible to touching and high voltages must be guaranteed and monitored
by using independent isolation monitors.

must make sure that any unpredictable movements do not cause damage neither to persons nor to
property.
Skilled personnel
Hardware
The skilled qualified personnel must feature a training and instruction for an assignment in the field of
electronic drive engineering. They must have knowledge of the standards and accident prevention
regulations for drive engineering applications and they must be familiar with this field of activity.
Eventually occurring dangerous situations are realized.
The local regulations (IEC, VDE, VGB) are known to the qualified personnel and they are observed during
the works.
Software
The skilled qualified personnel for handling the software must be trained to safely program the units in
the machines and installations. Incorrect parameter settings may cause improper and impermissible
movements. Any parameter settings have to be checked for faulty operation. Acceptance tests must be
thoroughly carried out according the four-eyes principle
Working environment
Incorrect handling of the units may cause damage to persons or property.
The units must be closed during operation.
Any unit covers must not be removed!
Disconnect the power supply prior to any works on electric connections. It must be ensured the battery
voltage is safely switched off.
Any voltages and residual voltages (buffer circuit) must be measured prior to any works on the unit.
Max. permissible voltage < 42 V.
High temperatures > 70 °C may arise.
The working environment may be dangerous for persons having electronic medical aids or appliances
(e.g. cardiac pacemakers). Sufficient distance to these electrical parts must be observed.
Exposure
During transport and storage the prescribed and specified climatic conditions must be adhered to.
The units must not be mechanically damaged. Warped and bent housing parts may influence or damage
the isolation distances. Damaged units must never be installed!
The units comprise parts which may be damaged by electrostatic discharge. The general
recommendations for handling electrostatic devices must be observed. Special attention should be paid
to strongly isolating plastic films and synthetic fiber.
For the operation it must be ensured that the environmental conditions in the switch cabinet are

2.1 Important notes
Check the device for mechanical damage.
Only devices in perfect working order can be mounted.
Disconnect the power supply prior to any assembly.
Disconnect the positive and the negative battery pole and the dc mains.
The device must only be mounted by suitably trained personnel.
The mounting position of the devices with a liquid cooling unit is arbitrary.
If the heat is not dissipated sufficiently the device switches off via its temperature watchdog.
Any bore hole dimensions for the fixation of the device must be taken from the dimension diagrams or
from the drilling plan.
Do not mark off the device.
The filter and the choke have to be mounted near to the device.
The line shields and the mounting plate must have surface-to-surface contact.
The power supply lines (battery line and motor line) must be routed separately from each other.
Observe the min. line cross-section.
A safe earth connection must be provided between the housing and the mass level (vehicle chassis
earth, earth of the switch cabinet)
Unshielded cable heads must be kept short.
Only use specified connectors.
Use vibration-proof screw connections.
Note:
Power supply cables between the BAMOCAR and the battery must be as short as
possible.
Long cables cause dynamic voltage drops due to the line impedance and as a
consequence the service life of the installed capacitors would be reduced.
