1. Description
General information
Figure 1
The Servo Amplifier BLD 7010 is a powerful PWM-module for brushless DC-Servomotors with
an output range up to 700 Watt.
Three operation modes are integrated
Torque-control
Speed-control by digital-encoder feedback
Speed-control by Hall sensors
The required operation mode is to be selected from the front side of the module
by setting jumpers. This BLD 7010 servo amplifier is protected against over current
overheat and short-circuit of the output stage against each other or to the power supply.
By the usage of advanced technology and power- MOSFETs a high efficiency up to 95%.
Due to the wide range of power supply voltage between 11 to 70 VDC the BLD 7010 can be
used very flexible with different kinds of power supplies within many applications.
The robust aluminum case has been constructed for different methods of mounting it,
therefor a fast integration is. Screw terminals and a durable controller-design allow a fast
and straightforward commissioning.

5. Safety notes
5.1 Skilled personnel
Installation and commissioning have to be done only by skilled personnel.
5.2 Laws
The user has to ensure the correct installation of the servo amplifier and additional
equipment according to valid laws and rules.
5.3 Remove load
For first commissioning the motor should run with free shaft which means without load.
5.4 Additional safety components
Electronic components are not free of failure or damage. Therefore plants have
to be installed with additional device and installation protecting components.
A safe and stable state has to be ensured in the case of damage of some devices, wrong
handling, cable disruption and other cases of any kind of malfunction.
5.5 Repair
Repairs have to be done only by authorized distributors or at the manufacturer. Unauthorized
opening and improper repairs of the device may cause danger to the user and the plant.
5.6 Danger
Care about having no power supply voltage all around the plant during installation of the
device. Never touch any voltage-carrying components.
5.7 Maximum input voltage
The input power supply voltage must not exceed 70 VDC. Voltages exceeding 70 V
or reversed connection will destroy the unit.
5.8 ESD
Do not touch any of the contacts of the device.
5.9 EMC
The BLD 7010 corresponds to the EC directives, standards and regulations 89/336/EWG article
10 and appendix 1 (EMV) amended by 92/31/EWG and 93/68/EWG and meet the requrements
with standard EN 61800-3 (1996) if the following directions are observed:
usage of a zinc plated mounting plate, well connected to earth
mounting of the drive by usage of toothed washers
usage of shielded cables to and from the unit
large area contact of the shielding with zinc plated mounting plate.
motor housing properly connected to earth

6.3. Input for set value
at use of external potentiometer (min. 10 kΩ) for set value the wiper has to be connected
to pin 17, the others to pins 14 and 16. Pin 15 and 18 have to be connected and J3 is to
be removed. at use of the internal set value via offset potentiometer pin 15 and 18 are left
without connection and J3 is to be set.
6.4. Timing
jumper J2 sets the timing of the hall sensor logic to reach an adaptation to several motor
types. The setting belongs to the direction of the phases. J2 changes the rotation sense of the
electrical field. For the brushless DC- Servomotors 4490 J2 must to be set.
6.5. Phasing
jumper J1 is for setting the phase shift of the signals of the Hall sensors. The correct value
is to provide by the manufacturer of the motor (see datasheet of motor). For 4490 motors
J1 must be removed.
6.6. Speed range
the speed range is to be set by jumper J10 and J11. One of four speed ranges is to be set. The
best result of speed control can be reached by setting the lowest acceptable range because
of the resolution.

The ready-signal is to show the status of the drive and can be used to provide a feedback
signal to other devices and controls. The open-collector output is normally turned off
which means the output is pulled to a positive level by an external connected resistor,
if there is no fault within the drive system.
In the case of a fault like under voltage, overvoltage, overheat or overcurrent the internal
transistor is on, the output is pulled to GND.
