This driver shall be kept away from dust, high-humidity environment and accidental contact shall
also be avoided. Enough space shall be reserved around the driver for ventilation and regulation.
When fixed, this driver shall be kept away from other heat source. Guarantee that this drive works
within the range of specified environment temperature. Installed on equipments with intense
vibration is not recommended; if not, please take precautions against vibration.
I. Wiring requirements:
1. Do not connect wire under charged circumstances.
2. Insulated wire and shielded wire matching well with driver’s voltage and current shall be selected
for the device; Specifications of power input line and motor connecting line selected for the driver
are shown in following table:
Table 1 Specification and length of wires
Current (A) Wire specification (
2
mm
) Max. length (m)
Power input line: 100 10 15
Motor output line: 100 10 15
WARNING
In any cases, signal line and logic control wire is not allowed to be bound, mixed or wired with
power input wire, output wire (motor wire) and other power lines, induced voltage generated
may cause interface, malfunction or direct damages upon the driver.
3. As driver does not have internal protection of opposite connection, please be sure to guarantee
that positive and negative poles of power input are consistent with that of external power supply,
otherwise, damages may be caused.
4. Please use proper tools for wiring and guarantee its correctness.
VII. Terminal connection diagram:
WARNING
All output connecting lines which control the terminal shall be kept away from wires
at power supply end and output end.
As output voltage supplied by the driver is 5V and current is 20 mA (small), other
external loads (such as data display instrument, indicator light) shall not be
connected, otherwise, damages may be caused.
n order to reduce unnecessary electronic signal interference, length of connecting
lines which control the terminal shall be shortened as much as possible, in case that
length of connecting line exceeds 0.5m, shielded wire shall be adopted.
VIII. Potentiometer control:
Potentiometer control: a 2W/10K potentiometer shall be used to control speed governing of the
driver; wiring diagram is shown below.
Installation method:
WARNING
Be sure to use shielded wire for signal input and shielding net shall be single-ended grounded.
Be sure to use shielded wire for all control signal connecting lines and shielding net shall be
single-ended grounded.
IX. Analog quantity control: External 0-5V control
WARNING
Be sure to use shielded wire for standard signal input and shielding net shall be single-ended
grounded.
Be sure to use shielded wire for all control signal connecting lines and shielding net shall be
single-ended grounded.
X．Pulse control: duty ratio regulation, frequency is 250 HZ, amplitude is 5V
WARNING
Be sure to use shielded wire for signal input and shielding net shall be single-ended grounded.
Be sure to use shielded wire for all control signal connecting lines and shielding net shall be
single-ended grounded.
XI. Motor forward and backward control:
Forward start Backward start
Forward start: FW and COM shall be shorted connected, i.e. forward run.
Backward start: BW and COM shall be shorted connected, i.e. backward run.
Note:
In case that COM terminal is not shorted connected with FW or BW terminal, driver is inoperative.
In case that COM terminal is shorted connected with FW and BW terminal at the same time, driver
is inoperative.
XII. Brake control:
Brake control
Brake control: STOP and COM terminal shall be shorted connected, i.e. motor will be immediately
stopped.
Note: In case of forward brake, if link between STOP and COM is not disconnected, backward start
is allowed, in order to restore forward start, disconnect STOP and COM terminal, and then
disconnect FW and COM terminal, reconnect them and forward start is restored. And so on for
backward brake.
XIII. Motor forward and backward limit:
Forward limit Backward limit
Forward limit: LIMIT FW and COM shall be shorted connected, i.e. forward limit.
Backward limit: LIMIT BW and COM shall be shorted connected, i.e. backward limit.
Note: in case of using limit function, need to know the details of logical relationship between
forward & backward start and forward& backward limit.
Control logic:
Firstly, confirm that COM terminal is not shorted connected with LIMIT FW or LIMIT BW, if
required by switch functions, limit direction which is opposite to moving direction shall be selected
for shorted connection.
Back and forth movement of motor:
Supposing that initial position will move forward, firstly, disconnect forward limit and connect
backward limit, and then connect forward start, motor is in direct motion; when it move forward to
certain position, disconnect backward limit, connect forward limit, motor will be immediately
stopped; after this, disconnect forward start, connect backward start, motor is in opposite running,
when it move backward to certain position, disconnect forward limit, connect backward limit, motor
will be immediately stopped. After the completion of above-mentioned actions, a cycle of control
logics has been finished, if repetition is required, above-mentioned control logic need to be
circulated.
XIV. Fault alarm:
Alarm output end
This port is fault alarm output end. It is in high level (DC5V) under working condition and in lower
level (DC0V) under alarm condition.
XV. Connection and description of DC motor:
1. The driver provides motor with voltage by “M1”“M2”terminal blocks.
Note: in case that forward start port is connected on control terminal, however, motor runs in
opposite direction, so the driver shall be disconnected, and then interchange “M1” and “M2” wiring,
motor will be in direct motion.
2. Please confirm that rated voltage of the motor matches well with output voltage of the driver.
