ACUVANCE EXSTRAIGHT Instruction Manual

Ultra-small digital speed controller Instruction Manual
• The state-of-the-art, ultra-compact power MOSFET <SOP*
of 0.25m .
Ω
• The MPRS system* 2 is adapted to a large current circuit. The ultra-small controller minimizes heat generation and significantly
reduces loss of battery energy.
• The current limiter setting enables smooth start-up and improves run-time.
• The brake rate adjustment enables faster braking.
1
* SOP : Today's mainstream system developed by KEYENCE for the first time as a surface-mount package and speed controller.
2
* MPRS (Metal Plate Radiation of heat Structure) : Hybrid structure which conducts current not through a copper foil but through a metal plate on the PC board.
It allows the best configuration with the FET.
CAUTION
The following symbols alert you to
important messages. Be sure to read
these messages carefully.
1. Ni-Cd or Ni-MH battery
WARNING: To prevent fumes, fire, and burns
Improper use of the battery is very dangerous. The battery must be handled carefully. Incorrect wiring or short-circuiting of the
cables may cause fire or fumes. Before connecting or disconnecting the battery to or from the ESC, be sure to turn off the
ESC's power switch. Do not charge the battery while it is connected to the ESC. When the battery is not in use, disconnect it
from the ESC or charger, and store it in a location with no wires or screws.
2. Connection of silicone cables
WARNING: To prevent fumes, fire, and burns
A faulty wiring or electrical contact (short-circuit) will damage the amplifier and may generate fire or smoke. In addition, both the amplifier
and battery may become irreparable. Refer to the electrical wiring diagram (note the colors and positions) and arrange the wiring properly.
Also, make sure to remove the battery before starting the wiring operation in order to prevent ignition or other accidents.
3. Mounting motor
WARNING: To prevent fumes, fire, and burns
Make sure to attach the provided shottkey diode and condenser to the motor. When the motor revolves, excessive voltage (surge
over-voltage) is generated, which may damage the amplifier under some circumstances. Mounting the shottkey diode and
condenser will control the voltage (surge voltage) applied to the amplifier. In addition, it will enhance the efficiency of the motor
revolution. Refer to the section of "Wiring and names of each part" on the following page and perform the mounting procedure
properly. Note that the shottkey diode has polar characteristics. Be sure to mount the shottkey diode in proper orientation.
4. Heat sink (Radiating fin)
WARNING: To prevent fumes, fire, and burns
Electricity flows through the metallic part at the top of the ESC.
chassis to make contact with the ESC. When a heat sink is attached, electricity flows through the heat sink. Exercise the same precautions.
5. Proper operation
CAUTION: To prevent accidents and product damage
Do not modify the ESC. Use it only for its intended purpose.
Keep the ESC away from flames or heat. Avoid splashing any liquid, such as water, on the ESC.
6. ESC mounting orientation
NOTE
: To prevent accidents and product damage
Except for at the outer side of the car,
side and PC board from any damage caused by car bodies contacting, collision, or turnover.
