2 Mounting the Drive
The BLDCdrive can be mounted only on the narrow side of the chassis. M4 screws should be
used in the two holes at the back of the drive. The amplifiers in the drive generate heat. To
operate the drive continuously at maximum power forced air cooling, as from a fan, should be
provided. Never use the drive in a space where there is no air fl ow or where other devices can
cause the surrounding air to be more than 40 °C. Never put the drive where it can get wet or
where metal particles can fall into it.
3 Connections
To use the BLDC50/100 Drive, the following items are needed:
•DC input of 12 to 48VDC
•Direction, Stop Mode(STMD), Enable, Speed Setting, Stop, Analog or multi-speed setting

perfor-mance between 12 and 48 Volts DC. Choosing the
voltage depends on the performance requirement and the
Motor/Drive heat-ing that is acceptable and/or does not cause a
motor/drive over temperature. Higher Voltages will cause the
Motor/Drive to operate at higher temperatures. Using power
supplies with Voltage outputs that are near the drive maximum
voltage may reduce the operational Duty-cycle significantly.
When choosing a Power Supply that is Regulated and is near the V- V+
Drive Maximum Voltage of 48 Volts, a Voltage Clamp may be
required to prevent over voltage when regeneration occurs. The BLDC50/10 0 Drive
R88A-RR08050S used for the Servo/Step Amplifier er will also work
BLDC50/100 User Manual
3.1 Connecting the Power(CN1)
Connecting the DC supply to power connector (CN1) according
to the diagram on the right. Use 16 AWG wire for V+ and V-.
Use 16 AWG for Earth Ground (G).
Care should always be taken when working with voltages.
The BLDC50/100 contains an internal 15A fast acting fuse.
The BLDC50/100 series drives are designed to give optimum
with the BLDC50/100 drive. The R88A-RR08050S can be purchased from Digi-Key
If you choose an unregulated power supply, make sure the no load voltage of the supply
does not exceed the drive’s maximum input voltage specifi cation.

3.3 Connecting the BLDC50/100 Communications
The BLDC50/100 is available with two types of serial communications, RS-232 (BLDC50/100) or
RS-485 (BLDC51/101). Each type requires a different hardware connection for interface to a PC
or other Host system. The RS-232 version comes with a cable that will provide the interface to an
RS-232 port through a DB9 style connector. The RS-485 version requires the user to provide
both the cabling and the RS-485 interface. Below are descriptions of how to interface both of
these se-rial communication types to a PC.
3.3.1 Connecting to a PC using RS-232(CN5)
Locate the BLDC50/100 within 1.5 meters of the PC. Plug the DB9 connector of the
communication cable that came with the drive into the serial port of the PC. Plug the small end
into the PC/MMI jack on the BLDC50/100. Secure the cable to the PC with the screws on the
DB9 connector.
Its baud rate is 9600bps which cannot be changed now.
Note: If the PC does not have an RS-232 serial port, a USB Serial Converter will be needed.
You can contact Lin Engineering to buy a USB to RS-232 converter.
The RS-232 circuitry does not have any extra electrical “hardening” and care should be taken
when connecting to the RS-232 port as hot plugging could result in circuit failure. If this is a con-
cern the RS-485 version should be used.
3.3.2 Connecting to a PC using RS-485(CN5)
RS-422/485 communication allows connection of more than one drive to a single host PC, PLC,
HMI or other computer. Its baud rate is 9600bps which cannot be changed now. It also allows the
communication cable to be long (more than 300 meters or 1000 feet). The use of Category 5 cable
is recommended as it is widely used for computer networks, inexpensive, easily obtained and cer-
tified for quality and data integrity.
The BLDC50/100 can be used with either Two-Wire or Four-Wire RS-422/485 implementation.
The connection can be point-to-point (i.e. one drive and one host) or a multi-drop network (one
host and up to 16 drives).
NOTE: To use the BLDC50/100 RS-422/485 version with the BLD Configurator software, it
must be connected in the Four-Wire configuration (see below)

Four-Wire Conguration
Four-Wire Systems utilize separate transmit and receive wires. One pair of wires must connect the
host’s transmit signals to each drive’s RX+ and RX- terminals. The other pair connects the drive’s
TX+ and TX- terminals to the host’s receive signals. A logic ground terminal is provided on each
drive and can be used to keep all drives at the same ground potential. This terminal connects
internally to the DC power supply return (V-), so if all the drives on the RS-422/485 network are
powered from the same supply it is not necessary to connect the logic grounds. One drive’s GND
terminal should still be connected to the host computer ground.
Because the host in a four-wire system never needs to disable its transmitter, software is simpli-
ed. Some converters make this process very difcult to implement and can delay communica-
tions.
NOTE: If the PC does not have an RS-485 serial port, a converter is required. You can
contact Lin Engineering to buy a USB to RS-485 converter.
Two-Wire Configuration
In a 2-wire system, the host must disable its transmitter before it can receive data. This must be
done quickly before a drive begins to answer a query. It is not make the transmit delay in a four
wire system.

Assigning Addresses
Before the entire system is wired, each drive will need to connect individually to the host computer
so that it can be assigned a unique address.
Once the drive has been connected to the PC as described above, launch the BLD Configurator
software. Apply power to the drive. If a drive has already been congured, click the Upload button
so that the BLD Congurator settings match those of the drive. Click on the Motion button and se-
lect the SCL operating mode. The numerals 0..9 or the special characters : ; < = > ? may be used
as addresses. Make sure each drive on the network has a unique address. Once the address has
been assigned, click Download to save the settings to the drive.

This signal is output if a warning is gener-
ated (overload warning function is acti-
vated)While, it turns OFF if the warning is
released.
- TLC - This signal is output when the motor output-
torque reaches the torque limiting value.
- IDLE - Conguring as general output
*1 Expand output functions are set through software conguration.
*2 the control module may be used to assign the required signals out of the eight input terminals
(X1 to X8) and the two output signal terminals (Y0 and Y1).
Y1-Y2 can be allocated as: Fault/Speed Out/MOVE/VA/Fault2/Warning/TLC/IDLE. (8 in total)
Input Signals Description
The signal state represents the “ON: Carrying current” or “OFF: Not carrying current” state of the
internal photocoupler rather than the voltage level of the signal.
CW/CCW
Switching the CW input will cause the motor to turn clockwise as viewed from the motor shaft,
while switching to the CCW input will cause the motor to turn counterclockwise. The starting
acceleration is set by the acceleration potentiometer (ACC/DEC) or command.
STMD (STOP MODE)
When STOP-MODE is OFF, the motor will stop according to the deceleration set by the acc/dec
potentiometer. When STOP-MODE is ON, it will stop the motor using electromagnetic brake op-
eration.
EN/RE (Enable/Reset)
When ENABLE is ON, the motor will be energized .When ENABLE is OFF, the motor will be
deenergized. Regardless any other input states, ENABLE being OFF has the highest priority, so
that it can be used as emergency stop. By disabling and enabling the drive, it can be reset.

FAULT
FAULT output an error signal when the drive is over-heat, over-current, over-voltage, under-volt-
age or internal voltage bad. The output voltage of error signal can be dened by SCL command
AO.
SPEED OUT
The motor output shaft output
6*(pole pairs) per revolution(default). And the pulse number can be set through the software.
MOVE
This signal is output during motor rotation.
VA
Speed reached command. If the difference between the actual motor speed and the input speed
reaches specied range, the drive will output this signal. The difference range can be dened in
0~+/-400rpm (the default range is +/-200rpm).
FAULT2
In order to avoid overload, the drvie can set the overload level, and use it as overload alarm sig-
nal. With this signal, user can distinguish the real cause of fault or warning.

3.5.2 Dip Switches
At the right side of BLD drive there are four switches. If users don’t
want use external power for the IO control, they can switch SW1
“ON” to choose the internal 5V power supply to IO control and “OFF”
means external power supply. When SW1 is “ON”, user should chose
common anode or common cathode control by SW2. SW2 is “ON”
that means user chose common anode IO control. SW2 is “OFF” that
means user chose common cathode IO control.
For RS485 version, SW4 is “ON” that means there is a 120 ohm termination resistor across the
TX+ and TX- terminals. SW3 is reserved.

The four switches on the right side of the BLD drive can be adjusted using a device that is
capable of fitting between the right side grating. Removing the outside layer is also possible but
not recommended due to sensitive nature of the drive electronics.
