1 Basic - Information
TVD3.2bl 3
Electronic equipment is not fault proof. This fact should be borne in mind for all possible
operating conditions.
Before installation or commissioning begins, this manual must be thoroughly read and
understood by the technical staff involved.
If any uncertainty arises, the manufacturer or dealer should be contacted.
TVD3.2 devices are power electric parts used for regulating energy flow for power plants.
Protection rating IP00.

General Information
The transistor 3-phase current servo amplifier SERVO-TVD3.2 in combination with the
brushless dc motor (ac synchro servo motor, EC motor provide a drive solution free of
maintenance and with a wide dynamic control range.
The drive displays the well-known good control characteristics of dc drives without the
disadvantages of the carbon brushes’ wear and the commutation limits.
The rotor moment of inertia is notably lower and the limit power is greater than with
equally constructed dc motors. This results in up to 5 times higher acceleration values.
The generated heat in the motor only occurs in the stator (cold shaft).
The motors always have the protection rating IP 65.
From the electrical view, the ac synchro motor is a synchro motor with a permanent
magnet rotor and a three-phase current stator.
The physical characteristics correspond to those of dc motors, that is, the current is
proportional to the torque and the voltage is proportional to the speed.
Current and voltage are precisely measured. The analogue circuits are simply
constructed.
It is possible to control the speed via the motor voltage, however, in order to achieve the
best control precision, always the tacho control is used.
The speed actual value is generated in the rotor position encoder plus bl-tacho.
The difference of the command value and the actual value is amplified in the speed
control loop circuit (P-I-controller) of the servo drive. This results in the current command
value, which is transferred to the three phase current controllers by means of the rotor
position signal. In the course of this the stator magnetic field leads the rotor magnetic
field by 90° electrically.
This field frequency is not controllable, it is automatically adjusted.
The motor currents are trapezoidal.
For dc and ac synchro servo amplifiers which are supplied by a dc bus, it must be
checked that the energy is fed back into the bus during brake operation (winding
machines, lifts, great centrifugal masses).
The ballast circuitry is rated for 3% duty cycle. An extended operating time can be
achieved by additional external resistors. (Option)

Applications
Machines and installations for all types with a drive power of up to 0.8kW.
Especially as 4Q-servo-drive for feed axes where the following is required:
- high dynamic acceleration and braking cycles
- a wide control range
- high efficiency
- small motor dimensions
- highly repeatable, accurate and quiet moves
- ‘cold shaft’
For speed or torque control or combined speed/torque control incorporated within or
independent of position control loops.
Drives with constant speed as in conveyors, spindle drives, pumps, transversal or
longitudinal pitch drives.
AC synchro-servo-drives are more compact than other electric drives.
Particularly suitable for:
component equipment inserting machines, sheet-metal working machines,
machine tools, plastic working machines, assembly machines,
knitting and sewing machines, textile working machines, grinding machines,
wood and stone working machines, metal working machines, food processing machines,
robots and handling systems, conveyors, extruders, calenders, and
many other machines and installations.
Note
Use bl-drives where braking operations are predominant, e.g. when
deceleration is mainly required:
- winding machines, lifts, great centrifugal masses
The braking energy is annihilated in the ballast circuitry or fed into the
mains through the use of an external dc bus converter.
Energy compensation is possible for drives with several axes.
Motor features
- protection rating IP 65
- compact
- suitable for rough surroundings
- suitable for high dynamic overload
- free of maintenance
