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

An AI sales agent prepares an order for MOVITRAC LTE-B+ frequency inverters from SEW-EURODRIVE: supply voltage and phase, power, internal EMC filter, brake chopper, IP20 or IP66 housing, motor match, braking resistor and external filter. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model and returns a verdict, every reason and the figures it computed. The type designation, power ranges and the ratings up to 11 kW are from public SEW-EURODRIVE documents; the prices and several rules are modeled for this demonstration and are not SEW-EURODRIVE's.

Scope: SEW-EURODRIVE MOVITRAC LTE-B+ inverter orders (0.37 to 37 kW, 110 to 480 V, IP20 and IP66/NEMA 4X): supply, power, filter, brake chopper, housing, motor match, accessories and an illustrative price. See everything this validator covers

This validator models an order for one MOVITRAC LTE-B+ inverter type at a time, not just the scenarios shown below. It separates what is public from what is modeled.

  • Public, from SEW-EURODRIVE documents — the type designation (power, line voltage 110-115, 200-240 or 380-480 V, interference suppression 0, A for C2 or B for C1, 1 or 3 phase, 1 or 4 quadrants, housing IP20, IP66 or IP66 with switch, 60 Hz variant), the power ranges for each line voltage, and the rated output currents up to 11 kW (from the LTE-B catalog tables; the 4 kW, 400 V, 9.5 A unit also appears on the LTE-B+ nameplate example). The braking resistors and external EMC filters come from the public accessories manual.
  • Modeled, not published by the company — every price is an illustrative figure typical for the industry, not a SEW-EURODRIVE price. So are the rated currents above 11 kW at 400 V and above 5.5 kW at 230 V, the 22 kW limit for the IP66 housing, the rule for an external filter, and the discount and approval thresholds.
  • What is checked — supply and power against the offered ratings, the internal filter and brake chopper against the supply and power, the motor against the inverter, the braking resistor and EMC requirement, the discount, and two figures the agent states (the order total and the rated output current), which must equal the computed ones.

Any LTE-B+ order that touches these rules is in scope — not only the scenarios pictured here. Not covered: MOVITRAC LTP-B, MOVITRAC B, MOVIDRIVE and MOVIMOT, fieldbus gateways, keypads, line chokes, parameter sets, and any real SEW-EURODRIVE price or term. The customers and the prices on this page are fictional or illustrative.

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
Filters, brake choppers and ratings that depend on supply and powerOnly with workarounds
The C1 and C2 filters are offered on different supplies, the brake chopper depends on the power, and the power list differs for each voltage and phase. A rules-based CPQ needs a rule per combination, and a new type code multiplies them.		Supply, phase, power, filter and brake chopper arrive in one request and every combination is checked on every call.
A motor that must fit the inverterOnly with care
A comparison of the motor power and current with the rating of the chosen unit, which itself comes from a table. It works, but the table must be kept in step with the catalog.		The rating is looked up and compared with the motor on every call.
An EMC requirement met by a filter inside or outside the unitOnly with care
The requirement links the site, the internal filter and an optional accessory on another line.		The site requirement, the internal filter and the external filter are checked together.
A total and a rated current the agent statesOnly with care
The price is recomputed on save, but nothing compares it with what the agent wrote in its request.		Both figures are computed on every call and compared with the stated ones.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The order has 0 inverters; at least 1 is needed.
2The 110-115 V inverters are single-phase units; a 3-phase connection is not offered.
3The selected quadrant version is not offered at this power: 1-quadrant units (no brake chopper) are offered up to 1.5 kW and 4-quadrant units (with brake chopper) from 1.1 kW.
4The 380-480 V inverters are 3-phase units; a 1-phase connection is not offered.
5A power of 1.5 kW is not offered for the selected supply voltage and phase.
6A power of 5.5 kW is not offered for the selected supply voltage and phase.
7A power of 0.37 kW is not offered for the selected supply voltage and phase.
8The selected internal filter is not offered for this supply: C1 is offered only on 230 V single-phase units, C2 only on 3-phase units, and the 115 V units have no filter.
9The IP66/NEMA 4X housing is quoted up to 22 kW; the order is for a larger unit.
10The motor power of 5.5 kW is larger than the inverter power of 4 kW.
11The motor rated current of 9.6 A is above the inverter rated output current of 9.5 A.
12A braking resistor needs a 4-quadrant unit with a brake chopper.
13The site EMC requirement is not met by the internal filter, and no external EMC filter is quoted.
14An external EMC filter is quoted only with a unit that has no internal filter.
15The discount is more than 10 percent of the gross price; a sales manager should approve it.
16The discount of $1,126 is more than 25 percent of the $4,500 gross price.
17An order of more than 500 inverters needs a supply and lead-time confirmation.
18The inverter is more than twice the motor power; an application engineer should confirm the sizing.
19The quote states an order total of $2,000; the modeled price build-up gives $4,500.
20The quote states a rated output current of 10.0 A; the selected unit is rated 9.5 A.
21The quote states an order total of $1; the modeled price build-up gives $6,050.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for MOVITRAC LTE-B+ frequency inverters from SEW-EURODRIVE: supply voltage and phase, power, internal EMC filter, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model and returns a verdict, every reason and the figures it computed. The type designation, power ranges and the ratings up to 11 kW are from public SEW-EURODRIVE documents; the prices and several rules are modeled for this demonstration and are not SEW-EURODRIVE's.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 150 MOVITRAC LTE-B+ inverters of 5.5 kW for a 380-480 V 3-phase supply. The motor is 7.5 kW and draws 16.0 A, and the site needs C1 EMC compliance. The rest of the request is on screen. The quote states an order total of $249,750 and a rated output current of 18.0 A.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with seven findings, all in one answer. The selected internal filter is not offered for this supply: C1 is offered only on 230 V single-phase units, C2 only on 3-phase units, and the 115 V units have no filter. The selected quadrant version is not offered at this power: 1-quadrant units (no brake chopper) are offered up to 1.5 kW and 4-quadrant units (with brake chopper) from 1.1 kW. The motor power of 7.5 kW is larger than the inverter power of 5.5 kW. The other four are on screen.
    6. 
      
  6. The validator returned seven 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 and against the stated total.
    7. 
      
  7. What this shows: for filters, brake choppers and ratings that depend on supply and power, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the power to 7.5 kW, the internal filter to none, the quadrants to 4 and the stated order total as to $219,750. It sets the External EMC filter to yes and the discount to $30,000.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The seven blocking findings are cleared; one approval remains for a person: discount above 10 percent.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the discount to $15,000 and the stated order total as to $234,750.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's total, $234,750, matches the quote.
    18. 
      
  18. Seven problems caught in one call, fixed in two passes, and a clean $234,750 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.
