Pressing Operation

As with pneumatic cylinders, push motion is a function to keep holding rods and sliders pressed against workpiece etc. Some models may not be used depending on the model of the actuator, so please make sure the following usage instructions and notes.

 
[Compatible with push motion]

 
[Notes]

  1. When pushing with the slider type, it is necessary to consider the allowable dynamic moment of the guide.
    For details, please refer to the correlation diagram page of push force and current limit value of each slider type. (Page1-389)
  2. RCP6 / RCP5 / RCP4 / RCP3 / RCP2 series are recommended for pushing applications.
    The RCP6 / RCP5 / RCP4 / RCP3 / RCP2 series are excellent in stopping stability at the time of pushing, and when compared with the RCA2 / RCA / RCS2 series of equivalent product cross section, a large pushing force can be obtained. Please contact our company for pressing on the RCA 2 / RCA / RCS 2 series.

 

[Adjustment of pressing force]

  • The pushing force (pushing force) can be adjusted by changing the current limit value of the controller.
  • Check the pushing force of each model on the 1-389-1-406 page model "Correlation diagram of pushing force and current limit value" and select the model that suits the condition.

 

* Please confirm the following caution concerning "Correlation diagram of pressing force and current limit value".

The correlation diagram between the pushing force and the current limit value shows the lower limit of the pushing force at each current limit value. Even if the current limit value is the same, depending on the aircraft, due to the individual differences of the motor and the variation of the mechanical efficiency, the pushing force lower limit value may be about 40% higher.
Except for the force control function, pushing force is not controlled by thrusting operation but by feedback control of current value. As a result, individual differences and variations may occur in the pressing force due to variations in the holding torque of the motor, individual differences such as ball screws and bearings, and changes in lubrication conditions. It is assumed that the holding torque of the motor itself has variations of about 30% due to the difference of the lot.

When accurate pushing force is required, please use actuator and controller which can use force control function. (See the right page)
