RS-485 network connection
Multiple –R model drive network can be built via dual RS-485 communication port by network
cable provided.
RS-485 Four-wire Configuration
RS-485 four-wire system utilize separate transmit and receive wires. One pair of wires connect
the host’s transmit signals(TX+/TX-) to each drive’s RX+/RX- receive terminals. The other pair
connects the drive’s TX+/TX- terminals to the host’s receive signals. A logical ground terminal is
provided on each drive and can be used to keep all the drives at the same ground potential. The
rst drive’s logical GND of the RS-485 bus must connect to host’s ground.
Four-wire Connection
Connect the drive’s RX+ to the TX+ terminal of the host controller,and connect the drive’s RX- to
the TX- terminal of the host controller . Connect the drive’s TX+ to the RX+ terminal of the host
controller,and connect the drive’s TX- to the RX- terminal of the host controller .
Connect the drive’s GND and the host’s GND to a same ground.
NOTE: The RS-485 port on the drive is isolated from internal circuitry of the drive. So the
GND of each drive’s RS-485 port must be connected together. The rst drive’s GND of the
RS-485 port must be connected to the GND of RS-485 port on the host PC or controller.
RS-485 Tow-wire Configuration
In a two-wire system ,the data transmitting and receiving use a same cable. the host must stop
its transmitting before receiving data. That means the host must stop transmit data before drive
begins to answer a query which just come from the host, otherwise the host cannot receive
any data witch sent from a drive. There is a transmit delay parameter that can be adjusted to
compensate for a host that is slow to disable its transmitter. This adjustment can be set over the
network using the TD command,it also can be set by using the STF Congurator software. Users
can set a shorter transmit delay in a four-wire system.
Two-wire connection
The RX+ and TX+ of the drive connect to the host’s + in parallel. The RX- and TX- of the drive
connect to the host’s - in parallel. Connect the drive’s GND and the host’s GND to a same ground.
NOTE: The RS-485 port on the drive is isolated from internal circuitry of the drive. So the
GND of each drive’s RS-485 port must be connected together. The rst drive’s GND of the
RS-485 port must be connected to the GND of RS-485 port on the host PC or controller.

2.4 Setting bus address and baud rate
STF drives (-R model and -C model) have two rotary switches to set the bus address and baud
rate.

Set drive’s RS-485 address by rotary switch S1
Set drive’s RS-485 baud rate by rotary switch S2
RS-485
Address
S1 is used to set drive’s RS-485 address, and the range is 0~F (0~15 in
decimal). If you want to set the drive’s RS-485 address range to 10~1F
(16~31 in decimal), you need to congure it in STF Congurator software.
2.4.2 CANopen address and baud rate settings(-C model)
Set drive’s CANopen address by rotary switch S1
Set drive’s CANopen baud rate by rotary switch S2
CANopen

Each node on a CANopen network must have a unique Node ID. Valid
ranges for the Node ID are 0x01 through 0x7F (1~127). Node ID 0x00

is reserved in accordance with CiA301. The Node ID is selected using
rotary switches and software; one sixteen position switch set the lower four bits (0~F) of node ID,
while upper three bits of node ID are congured by STF Congurator software. Each time when
Node ID is changed, a power cycle is required before the new Node ID is valid.
Please refer to the CANopen manual for more information.

2.6 Choosing A Power Supply
The main considerations when choosing a power supply are the voltage and current requirements
of the application.
2.6.1 Voltage
The STF drive and motor is designed to give optimum performance between 24~48 Volts DC. Choosing
the voltage depends on the performance needed and diver/motor heating that acceptable and/or does
not cause a drive over-temperature. Higher voltage will give higher speed performance, but will cause
the drive to produce higher temperatures. Using power supplies with voltage outputs that are near the
drive maximum may signicantly reduce the operational duty cycle.
The STF03/06 drive extended range of operation voltage can be as low as 11VDC minimum to as
high as 53VDC maximum. When operation below 11VDC, the STF03/06 series will work unstable.
The supply input cannot go blow 11VDC for reliable operation, otherwise under voltage alarm will be
triggered. STF03/06 drive will stop working when this alarm is triggered.
The STF10 drive extended range of operation voltage can be as low as 18VDC minimum to as high as
75VDC maximum (18-53VDC for STF05 Drives). When operation below 18VDC, the STF05/10 series
will work unstable. The supply input cannot go blow 18VDC for reliable operation, otherwise under
voltage alarm will be triggered. STF05/10 drive will stop working when this alarm is triggered.
STF03/05/06
If a regulated power supply is used, and that is near the driver maximum voltage of 53VDC ,a voltage
clamp may be required to prevent the voltage over 53VDC which will occurs a overvoltage fault. When
using an unregulated power supply, make sure the no-load voltage of the supply does not exceed the
maximum input voltage 53VDC.
STF10
If a regulated power supply is used, and that is near the driver maximum voltage of 75VDC ,a voltage
clamp may be required to prevent the voltage over 75VDC which will occurs a overvoltage fault. When
using an unregulated power supply, make sure the no-load voltage of the supply does not exceed the
maximum input voltage 75VDC.
2.6.2 Current
When STF drives work with different motors, the recommended power supply output current
capacity under different supply voltage is shown in below table. The STF drive power supply

3.1.1 X1, X2, X3, X4 digital input signal
X1, X2: optically isolated, differential, 5-24VDC, minimum pulse width 250ns, maximum pulse
frequency 2MHz
X3, X4: optically isolated, differential, 5-24VDC, minimum pulse width 100μs, maximum pulse
frequency 5KHz
X1 can be used as general purpose input.
X2 can be used as general purpose input.
X3 can be used as CW limit input or general purpose input.
X4 can be used as CCW limit input or general purpose input.
Please use STF Congurator software for X1,X2,X
3 and X4 function configuration.
Following graphs shows some common connection methods for the inputs:
frequency 5KHz
X5 can be used as enable input or general purpose input.
X6 can be used as alarm reset input or general purpose input.
X7 can be used as general purpose input.
X8 can be used as general purpose input.
Because the input is an optically isolated circuit, a 5-24V power supply is needed. For example,
you can use the power supply of the PLC when you are using a PLC control system, but if you
want to connect a relay or mechanical switch to the input , you must need a power supply.
XCOM is an electronics term for a single-ended signal connection to a common voltage. In the
case of STF series, if you are using a sourcing (PNP) input signals, you need to connect XCOM
to the ground (power supply -), if you are using a sinking(NPN) input signals ,the XCOM need to
connect to the power supply +.

• Never use the drive in a place where there is no air flow or the surrounding air is
more than 40℃.
• Never put the drive where it can get wet or where metal or other electrically
conductive particle particles can get on the circuity.
• Always provide air flow around the drive. When mounting multiple STF drives near

RC-880 Regeneration Clamp
RC-880 is used to limit increase in power supply
voltage when the motor is decelerating under load.
This is commonly referred to as "regeneration".
RC-880 can clamp the regeneration and prevent
the power supply and/or drive being damaged or
destroyed. Connect the RC-880 between the power
supply and the drive.
