Sample Validation Workflow

The goal of a sample evaluation is not only to confirm that a product can rotate or transmit torque. It should also answer whether the selected configuration is suitable for the customer's mechanical, electrical and operating conditions.

This workflow is intended to make the first evaluation more structured and reduce avoidable setup delays.

Before the Sample Is Ordered

Confirm the exact configuration being evaluated.

At minimum, record:

  • product model
  • ratio or output-speed target
  • driver / no-driver configuration where applicable
  • encoder requirement where applicable
  • operating voltage where applicable
  • required communication interface where applicable
  • mounting or shaft requirements that affect the sample
  • sample quantity

Use the public Engineering Pack before ordering when one is available.

When the Sample Is Received

Before installation:

  1. confirm the model and quantity received
  2. compare the physical configuration with the order or quotation
  3. check for visible shipping damage
  4. identify the exact driver / connector / cable configuration where applicable
  5. use the documentation matched to that configuration

If anything is unclear, confirm the configuration before wiring or modifying the sample.

Step 1 - Mechanical Fit

Check the sample against the customer's assembly:

  • outer diameter and axial length
  • mounting-hole pattern
  • output shaft or output flange
  • locating features
  • cable and connector clearance
  • motor-side interface for gearbox-only evaluations
  • direction of external radial and axial loads

For public models, use the released simplified STEP for packaging and mounting evaluation. Use the controlled drawing before final production release.

Step 2 - First Power-Up or No-Load Check

For actuator or motorized configurations, first confirm the basic setup before applying the real application load.

Typical checks include:

  • supply voltage
  • wiring and connector orientation
  • communication link where applicable
  • enable / basic command response
  • direction of motion
  • encoder feedback where applicable
  • no-load motion

Detailed wiring, protocol and firmware-specific instructions must match the actual driver configuration.

For a gearbox-only sample, first confirm free assembly, input/output alignment and the selected motor interface before loaded testing.

Step 3 - Functional Test

Run the motion required by the application and record the operating condition.

Useful information includes:

  • output speed
  • applied or estimated load
  • motion cycle
  • acceleration / deceleration behavior
  • current where applicable
  • temperature where relevant
  • observed backlash, vibration or noise where relevant
  • any communication or control fault

Do not compare a short sample test directly with a lifetime or continuous-duty claim unless the applicable rating and test condition are documented for that configuration.

Step 4 - Application Test

After the basic function is stable, evaluate the sample in the real or representative mechanism.

Confirm:

  • actual installation geometry
  • actual load direction
  • continuous and peak load condition
  • peak duration
  • duty cycle
  • ambient / cooling condition
  • power-off behavior if important
  • controller / current-limit conditions for motorized actuators

If a Problem Appears

Send the smallest useful set of evidence first:

  • exact model and configuration
  • supply voltage
  • controller / driver information
  • command or operating mode
  • what was expected
  • what actually happened
  • fault code or log if available
  • short video or photo if it helps show the issue

This is usually more useful than sending a long general description without the operating condition.

Model-Specific Starting Points

Quick Start, detailed CAN and firmware-specific integration documents are supplied after configuration review.

32P

Public starting resources:

The current public 32P STEP represents the 4-stage reference only. Request configuration-specific CAD for other stage arrangements.

When the Sample Is Ready for the Next Stage

A successful sample test should lead to a concrete engineering decision, for example:

  • keep the current configuration
  • change the ratio
  • change the motor / driver
  • revise the mounting or output interface
  • request a controlled drawing
  • integrate into the next prototype
  • prepare for Design-In
