Precautions when using our products

= READ CAREFULLY =
Using these products outside of their rated conditions or under conditions that fail to meet requirements for the power supply will result in misoperation and serious damage.
Tonegawa-Seiko accepts absolutely no responsibility for damage or misoperation occurring in this manner.
Moreover, these products were not designed or manufactured for applications for supporting human life. Tonegawa-Seiko accepts absolutely no responsibility when damage occurs when customers use these products under such applications.

  1. Servo ratings
    1. PS-050 Operating voltage: 4.8V to 8.4V DC;
      Power supply current capacity: More than 10A
    2. SSPS-105
      for 12V specifications:12V DC +/-3V; Power supply current capacity: More than 12A
      for 24V specifications: 24V DC +/-6V; Power supply current capacity: More than 12A
    3. Input pulse width: within 1.5 m sec +/-440μ sec.
      (SSPS-105 requires 12mA for photo coupler drive)
    4. PS-050, Operates +/-45° at 1.5 m sec +/-400µ sec (along with) SSPS-105
    5. As labeled on the "CPU", SSPS-105 digital servo ignores receive pulse width variations of more than +/-400µ S. This is for "over-run" protection.
  2. Please refer to this when using any of our servo actuators.
  3. When using lead-acid storage batteries, always monitor the internal resistance to avoid the power voltage drop down.
    Carefully watch for peak current a drop in voltage. If this resistance becomes too large, the rush current when starting the motor can cause the internal voltage drop and cause trouble. Note that even if a generator or similar device is used for charging during operation, a shortage of electrical power may occur when operation performed is over an extended period of time. Calculation of the power must be implemented during the design period. More than 90% of the problems we consult about are related to power supply problems..
  4. This R/C servo has unique characteristics and weak points. Other than the information provided on our home page, we can provide consultation about points that are unclear.
  5. When using this servo, when turning the switch on, feed the control signal first and then turn on the power. When turning off the power, turn off the power first and then turn off the control signal. This is the most fundamental rule for power control systems. The power line for this servo has a large-capacity internal capacitor. If the signal and power supply are turned off simultaneously, the rest of capacity may cause the servo to move slightly. This is because part of the control pulse signal is missing when the control switch is turned off.
  6. Due to our policy of ongoing product improvement, items are subject to change without notification. If such a change will cause inconvenience for you, please notify us before ordering and we will try to accommodate you.
