4) mailing address
Users can control up to 30 DS-OLS7-FRS4 drives simultaneously using the RS-485 bus.
The drive communication address setting uses a 5-digit DIP switch.
The address setting range is 1-32, where address 32 is reserved for the system. When the
drive address setting is greater than 31, it needs to be set and saved using the upper
debugging software.
And the switch must be set to all OFF (default is 1).
Notes
1) One controller can control up to 30 DS-OLS7-FRS4 drives simultaneously via
the RS-485 bus.
2) The communication address setting of each drive must be unique,
otherwise it will cause communication error.

8)Idle current
After 500 milliseconds of no pulse input, the current will automatically enter the idle current
to reduce motor heating. The current is restored to the set value during pulse input.
9)Indicator function
This product has 2 LEDs indicating that the light shows the working status:
1. Green light: (work instructions)
When the motor has no current, the lamp flashes 2 times (0.5 second low level, 0.5 second
high level) to complete the 2 second high level, and then recirculate.
It is always on when the motor is running.
The lamp flashes when the motor is running (0.5 second low level, 0.5 second high level).
2. Red light: (fault indication)

4. Power Supply
4.1 Voltage
The chopper driver continuously changes the size and direction of the motor winding voltage
and detects the current to obtain accurate phase current. If both high efficiency and low noise
are to be ensured, the driver supply voltage shall be at least 5 times the motor rated phase
voltage (that is, the motor rated phase current × phase resistance).
If you need the motor to get better high speed performance, you need to increase the driver
supply voltage.
If power is supplied from a regulated power supply, the supply voltage shall not exceed 48V.
If non-stabilized power supply is used, the voltage shall not exceed 34V.
Because the rated current of non-stabilized power supply is full load current ; When the load is
light, such as when the motor is not running, the actual voltage is up to 1.4 times the rated
voltage of the power supply. For smooth and quiet operation of the motor, choose low voltage.
4.2 Current
The maximum supply current shall be the sum of the two phase currents. Usually, the amount
of current you need depends on the type of motor, voltage, speed, and load conditions. The
actual supply current value is much lower than this maximum value, because the driver USES
a switching amplifier that converts high voltage and low voltage current into low voltage and
high current. The more the supply voltage exceeds the motor voltage, the less supply current
is required. When the motor is connected to a 48V power supply, the output current of the
power supply is half of that of the 24V power supply.
4.3 Regeneration of Discharge
When the motor slows down, it ACTS like a generator, converting the kinetic energy of the load into
electricity. Some energy is consumed by the driver and motor. If your application has a large load
running at high speed, a considerable amount of kinetic energy can be converted into electricity.
Easy to cause the drive alarm (overvoltage) may even cause damage to the drive.
Since this driver has the function of anti-power connection, it can prevent the driver
damage caused by power connection, so the use of external regenerative discharge
device does not work.
When your application has a large load running at high speed, please contact the
company in advance, shield anti - reverse connection function, and external
Power Supply

regenerative discharge device. Please note that the positive and negative terminals of
the power supply should not be inversely connected when there is no anti-inversely
connected function.
The driver damage caused by inversely connected power supply cannot be guaranteed.
5. Motor Connection
Warning: When connecting the motor to the drive, first make sure that the power of the drive is
turned off. Make sure that the unused motor leads are not short-circuited with other objects.
The motor cannot be disconnected while the drive is energized. Do not connect motor leads to
ground or power.
1) Four-wire motors can only be connected in one way.
2) Six-wire motors can be connected in two ways: full group and half group. In the full group mode, the
motor has greater torque at low speeds, but it cannot run as fast as in the half group. When the whole
group is running, the motor needs to run at less than 30% of the half-group current to avoid overheating.
3) Eight-wire motors can be connected in two ways: series and parallel. The series mode has greater
torque at low speeds and less torque at high speeds. When running in series, the motor needs to run
at 50% of the current in parallel to avoid overheating.
Power Supply / Motor Connection

Notes
1) The corresponding colors of different motors are different. When using the
motors, the specifications of the motors shall prevail. For example, the colors of
57 and 86 motor wires are different.
2) The phases
are relative, but the windings of different phases cannot be
connected to the terminals of the same phase of the driver (A +, A- is one phase,
B +, B- is the other phase). If the motor direction is different from the expected
direction, only A + , A-.
3) This driver can only drive two-phase hybrid stepping motors, not three-phase
and five-phase stepping motors.
4) The method of judging whether the stepper motor is connected in series or in
parallel: Rotate the shaft of the motor directly by hand without connecting the
driver. If it can rotate easily and evenly, it means that the wiring is correct. If it
encounters large resistance and unevenness Accompanied by a certain sound
indicating that the wiring is incorrect.
6. Signal Input
6.1 Pulse Signal : STEP
The driver port has a built-in optocoupler, which can accept 5-24VDC single-ended or
differential signals, and the highest voltage can reach 26V. Its change from off to on is
understood as accepting a valid pulse edge command. For the common anode, the low level
is valid (the common negative is valid for the high level). At this time, the driver will drive the
motor to run one step according to the corresponding timing. For the normal operation of the
driver, the duty cycle of the effective level signal should be below 50%. In order to ensure the
reliable response of the pulse signal, the duration of the pulse effective level of the subdivided
driver should not be less than 1us. The signal response frequency of the subdivision driver is
500KHz, and an excessively high input frequency may get an incorrect response.
6.2 Direction Signal : DIR
Can accept 5-24VDC single-ended or differential signals, the highest voltage can reach 26V.
The on / off of the internal photocoupler at this end is interpreted as two directions of motor
operation. The change of the direction signal will change the direction of motor operation. The
floating of this end is equivalent to the input high level. It should be noted that the subdivision
driver should ensure that the direction signal is established at least 10us ahead of the pulse
signal input to avoid the driver s incorrect response to the pulse signal. When the motor is
commutated, it must be switched after the motor decelerates and stops to the starting
Motor Connection / Signal Input

page│11
frequency. The commutation signal must be changed after the last STEP pulse of the previous
direction signal and before the first STEP pulse of the next direction. When no commutation is
required, the direction signal terminal can be left floating.

7. Typical Signal Connection
7.1 Common Positive Connection
Notes The pulse and direction terminals have a constant current input function, which
can be directly connected to the input signal without external series resistor step-
down current limiting protection. The VCC value is 3.5-26V.
Typical Signal Connection

8. Typical Connection of Signal Output
8.1 Relay Connection
Notes When the relay is connected, it is required to connect diodes at both ends of the
relay (such as IN4000 series)
8.2 Optocoupler Connection
The alarm output is optically isolated, with a maximum voltage of 30VDC and a maximum
saturation current of 50mA.
When the driver is working normally, the output is closed.
When the drive fails, the output is left floating.

Typical Connection of Signal Output / Wiring Requirements
9. Wiring Requirements
1) In order to prevent the driver from being disturbed, it is recommended to use shielded cable
for the control signal, and the shield layer should be shorted to the ground. Except for special
requirements, the shielded wire of the control signal cable is grounded at one end: the upper
end of the shielded cable is grounded The driver end of the wire is left floating. Grounding
can only be performed at the same point in the same machine. If it is not a real ground wire,
the interference may be serious, and the shielding layer is not connected at this time.
2) Pulse and direction signal lines and motor lines are not allowed to be bundled side by side,
preferably at least 10cm apart, otherwise motor noise may easily interfere with pulse direction
signals, causing inaccurate positioning of the motor, system instability and other faults.
3) If one power supply is used for multiple drives, a parallel connection should be adopted at the
power supply. It is not allowed to connect one to the other in a chain.
4) It is strictly forbidden to plug and unplug the drivers strong current (motor and power)
terminals. When the charged motor is stopped, a large current still flows through the coil.
Plugging and unplugging the strong current (motor and power) terminals will cause a huge
momentary induced electromotive force to burn out. driver
5) It is strictly forbidden to add lead to the terminal after adding tin, otherwise the terminal may
be damaged due to overheating due to the increased contact resistance.
6) The wiring head must not be exposed outside the terminal to prevent the driver from being
accidentally shorted.

10.Installation Dimensions (unit : mm)
[ Drive installation ]
Install with narrow sides, and install with M3 / M4 screws through the holes on both sides.
The power device of the driver will generate heat. If it works continuously under high input
voltage and high power conditions, it should expand the effective heat dissipation area or
force cooling.
Do not use in places where air circulation is not allowed or where the ambient temperature
exceeds 40 ° C; do not install the drive in humid or metal shavings.
