Standard Reciprocating Drive Motor #E -SPN04325

If there the drive is not currently in place ,follow theses step below.

Direct Rotary Drive Installation Step

---

 

1. Route the drive cable through the X Y stage.

2. Position and insert the motor drive through the stage.

1. Orient the drive so the green sensor port faces the right side.

2. Secure the drive with 7 x SHCS 8-32 X .625" long screws  
   (310-280-05 / BM310280-09)

3. Connect the 2 cables on the slot on the right, behind the frame (the Motor Power Chord and the Encoder Chord).



⚠️
Always power off the instrument before connecting cables or installing any
load cell or accessory.

If Integrated module

---

In certain configurations—particularly when there are requirements for speed and/or torque—a module with an integrated motor has been recommended.

The difference, therefore, is that to change modules (from reciprocating to rotary, for example), it is necessary to uninstall the module with it motor from the stage.

1. Open the upper back door of the MFT-5000.

2. Insert the motor drive on the stage.

1. Secure it with 6 x 8-32 x .375” BM310280-05 9/64

2. Connect the 2 cables on the slot behind the right frame.

3. Skip the next step.

 

Technical specification:

---

Proper alignment of the sample on the reciprocating holder helps maintain its rated life.

The load factor applied to any reciprocating system is still the main factor determining its rated life.

---

The reciprocating mechanism can withstand high loads when used within its designed operating conditions. However, the general mechanical principle described below cannot be avoided.

rated life: the total travel distance that 90% of linear guides can reach

 

X₀ → Maximum X Differential Position

The maximum offset of the load along the X-axis relative to the center of the drive.
This value accounts for the total stroke displacement.

Y₀ → Maximum Y Differential Position

The maximum offset of the load along the Y-axis relative to the center of the drive.

Load

It depends on the position of the applied force. Refer to the following document for guidance on determining the maximum allowable load per test.

For example, if the X.Position is 0 mm and the stroke is 10 mm, then X₀ = 5 mm.

You are welcome to use this sheet to estimate your reciprocating drive’s rated life

Based on the summarized parameters, including the X–Y alignment relative to the reciprocating center. Please refer to the maintenance section at the end of this manual for more information.

⚠️

This information and the maintenance assessment should be taken into consideration during high-load testing procedures.

 

 

• Adjustable Stroke length: 0.1-30 mm

• Frequency: 0.1-80 Hz ( 80 Hz @ 1 mm, 60 Hz @ 2 mm, 20 Hz @ 25 mm).
⚠️
• The maximum allowable frequency is determined by the current stroke length. The respective limits must not be exceeded.
• Some reciprocating drives are not fully covered by this specification, e.g., SPN04316 – up to 15 Hz. Please refer to your packaging list if unsure or unaware of this information, or contact Rtec Support for assistance.

• (Option) LVDT Linear Encoder Range: 25.4 mm (+/- 12.7 mm); Resolution: 1 um

When using the reciprocating system in combination with the LVDT, the stroke length limitation becomes 25.4 mm. The stroke length cannot be accurately measured or guaranteed beyond this value.

1. Position the reciprocating drive on the base.




Ensure that the black connector underneath the module is properly aligns and connects with the green connector on the base.

2. Use two 8-32 screws (BM310280-12) to secure the reciprocating drive.

• Place the universal sample holder on top of the reciprocating drive

• Tighten the captive screws using a 7/64" Allen key.

1. Position the sample into the universal holder.

Max sample width: 1.61” (4.089cm).
Other than the width, the rectangular sample has no specific size requirements.

2. (Optional) You can also loosen the two nuts first to fit the sample size before.

3. Secure the sample in place using an 8/32" Allen key

1. On the MFT Software , disable the drive by clicking on the ON button.




Click on “ON” to switch off the motion. The module must be “OFF”.
The drive must be disabled in order to freely move the reciprocating and get access to the adjustment screws.

2. Drive disabled, turn the central shaft until the stroke adjusting assembly appears through the front opening of the module.



 

3. Using a 5/64” Allen wrench, loosen the brake screws on both sides



 

4. Insert a 9/64” in Allen wrench into the center adjustment screw to adjust the stroke length.



 



Turn clockwise (right) to decrease stroke length.
Turn counterclockwise (left) to increase stroke length.

5. Measure the amplitude with the LVDT if available in your configuration, a ruler or a dial gauge while the drive motion is on.

Manual measurements of the reciprocating amplitude may differ slightly from the drive motion amplitude. For accurate stroke length, measure with a dial gauge while the drive is running, or use the LVDT sensor if avalaible.

6. After adjusting, re-tighten the brakes with the 5/64” in Allen wrench.
