Predictika · Conveyor drive configuration checks

An AI sales agent's RollerDrive order, checked before it goes out

An AI sales agent assembles an order for 50 mm RollerDrive motorized conveyor rollers for a warehouse conveyor: the supply voltage and motor power, the gear ratio, the conveyor speed, the torque the application needs, the reference length and drive head, the static load and the ambient temperature. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public EC5000 IP66 data sheets and returns a verdict, every reason and the figures it computed.

Scope: Interroll RollerDrive EC5000 (50 mm, IP66): motor, gear ratio, speed, torque, length, drive head, load and temperature. See everything this validator covers

This validator models the public data sheets of the EC5000 RollerDrive (50 mm tube, IP66 version for 0 to 40 °C), not just the scenarios shown below.

  • Motor and gear ratio — 24 V or 48 V, 35 W or 50 W, and the seven listed gear ratios (18:1 to 108:1), each with its published speed range and its rated and acceleration torque.
  • Length, drive head and load — the 500 to 1,500 mm reference length, the installation length (reference length plus 14 mm for a female thread or 35 mm for a PolyVee drive head), and the maximum static load for each length with or without a drive head.
  • Temperature and stated length — the 0 to 40 °C range of this IP66 version, and whether the installation length stated on the order equals the one the data sheet gives.

Any EC5000 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Interroll publishes none here, so no price build-up or line-item quote is produced), other RollerDrive series (EC310, the IP54 versions), controls and power supplies, tube lagging and sleeves, and sizing the torque for a given conveyor. Assumptions: torque figures are in centi-newton-metres from the published Nm values; a length between two listed load steps uses the next longer step; a reference length of exactly 500 mm goes to a person because the data sheet notes the minimum depends on the drive box variant; the speed minimums are the rounded values in the data sheet.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Rated torque, acceleration torque and speed range that change with each gear ratio and motor powerOnly with care
A table of values per ratio and power, each checked against the application, and kept in step with the data sheet.		The motor, ratio and requirements are in one request and every limit is checked on every call.
A load limit that falls as the tube gets longer and differs with a drive headOnly with care
A step table by length and head type, with a rule for lengths between the steps.		The length, head and load are in one request, and the limit is looked up and compared on every call.
A stated installation length that disagrees with the reference length plus the head allowanceOnly with workarounds
The length comes from an addition that depends on the head; checking a stated figure against it takes extra formulas.		The stated figure is one more field in the request and is compared with the computed length on every call.
Ambient temperature outside the range of the IP66 versionEasy
A simple range rule on one field; routine in a product-rules CPQ.		The same rule, checked together with all the others on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent assembles an order for 50 mm RollerDrive motorized conveyor rollers for a warehouse conveyor: the supply voltage and motor power, the gear ratio, the conveyor speed, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public EC5000 IP66 data sheets and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please prepare an order for 16 Interroll RollerDrive EC5000 rollers (24 V, 35 W) with a 42:1 gear ratio and a PolyVee drive head, a reference length of 1,300 mm. The conveyor runs at 400 mm/s and needs 250 cNm of continuous torque and 500 cNm at acceleration, with a static load of 600 N per roller. The rest of the request is on screen. The order states an installation length of 1,335 mm.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The application needs 250 cNm of continuous torque; this motor and gear ratio give 207 cNm rated. The static load is 600 N; the data sheet limit for this length and drive head is 350 N.
    6. 
      
  6. The validator returned two blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for rated torque, acceleration torque and speed range that change with each gear ratio and motor power, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the motor power to 50.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The static load is 600 N; the data sheet limit for this length and drive head is 350 N.
    12. 
      
  12. One finding cleared. Still blocking: static load above the limit for this length.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the drive head to female thread (no drive head) and the stated installation length to 1,314 mm.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared.
    18. 
      
  18. Two problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    19.
