Predictika · multi-axis drive line-ups: Motor Modules, infeed, safety, lead time, discount and total price

An AI sales agent's drive line-up quote, checked before it goes out

An AI sales agent prepares a SINAMICS S120 drive line-up quote for a fictional machine builder, with the total price it expects. Before the quote goes out, the agent sends it to Predictika’s validator, which checks it against Motor Module current, infeed and DC bus, control, safety, mechanics, lead time and discount rules, compares the total the agent states with the one it computes, and returns a verdict with every reason.

Scope: Siemens SINAMICS S120 multi-axis drive line-up quotes: Line Modules, Motor Modules, SIMOTICS motors, Control Unit, safety, commissioning, lead time, discount and total price. See everything this validator covers

This validator models booksize and chassis S120 Line Modules, single and double Motor Modules, and SIMOTICS servo, main and induction motors, with up to four motor slots per quote. It handles any combination of infeed, Motor Module, motor, control mode, supply voltage, safety, commissioning, cabinet, lead time and discount choices the model supports, not just the scenarios shown below.

  • Line Modules and Motor Modules — Basic, Smart and Active Line Modules in booksize and chassis form, single and double Motor Modules, and the current, power, voltage and form-factor limits between them.
  • Motors and feedback — SIMOTICS servo, main and induction motors with DRIVE-CLiQ encoder, resolver or no encoder, including the Sensor Modules resolvers need.
  • Control, safety and mechanics — Axes per CU320-2 Control Unit in servo and vector mode, Safety Integrated Extended Functions, braking, harmonics, motor cable length and reactors, cabinet width and chassis cabinet integration.
  • Service, lead time and pricing — Commissioning service with the safety acceptance test, lead time against the need date, line-item pricing with discount authority by quote size, and a check that the total price the agent states matches the validator total.

It does not cover other Siemens drive families, standalone parts orders, engineering of motor sizing from a load profile, real list prices or contract terms, or any real customer.

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 or Revenue Cloud) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator catchesTypical rules-based CPQPredictika
Motor current checked against the Motor Module on every axisOnly with care
Each axis is a separate comparison of a motor property with a module property, and a double module drives two motors at once.		Every axis is checked in the same pass, and the finding comes back with the others.
DC bus load against the infeedOnly with workarounds
The load is a sum over axes scaled by simultaneity, then compared with the Line Module rating at two thresholds, so it takes a chain of dependent price and validation rules.		The load is computed once and used for the size check and the 90 percent approval.
Line Module kind and form factor against the siteOnly with care
Harmonics, regeneration and voltage each depend on the Line Module chosen, and 690 V needs a different form factor altogether.		Kind, form factor and voltage are checked together, and every miss is returned.
Safety option as a prerequisite for encoders and commissioningEasy
A dependency between options is a standard product rule.		The same rule, returned with the other findings.
Lead time across several componentsOnly with care
The longest of the Line Module and every motor must be compared with the need date.		Lead time is computed once from the chosen items and compared with the weeks needed.
Discount authority that scales with quote sizeOnly with care
Engineer and manager limits that depend on the size of the quote are doable but tend to be hard-coded per tier.		Limits come from the same computed list price, so approval and block follow the quote size.
The total price the agent statesOnly with workarounds
Comparing a stated total with a computed one means a separate rule per quote layout, and price rules rarely run on stated figures.		The stated total is a field in the request and is checked against the computed total.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches
Click to expand
    
Every rule is checked on every call, in whatever order the choices arrive, and one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
RuleEffectWhat it checks
1blockEach motor must not draw more rated current than its Motor Module delivers
2blockLine Module and Motor Modules must share a form factor (booksize with booksize, chassis with chassis) on one DC bus
3blockThe supply voltage must not exceed the Line Module rating; 690 V needs a chassis line-up
4blockDC bus load, the sum of motor power times simultaneity, must not exceed the Line Module rating
5approvalA load above 90 percent of the Line Module rating needs drive engineering confirmation
6blockA site that requires low line harmonics needs an Active Line Module with Active Interface Module
7blockA Basic Line Module cannot feed energy back, so heavy braking duty needs a Braking Module and resistor or a Smart or Active Line Module
8blockOne CU320-2 Control Unit controls up to 6 axes in servo mode or 4 in vector mode
9blockSafety Integrated Extended Functions need an encoder on every axis and the commissioning service with a safety acceptance test
10computedResolver motors need an SMC Sensor Module per axis, which is priced into the quote
11blockA booksize line-up must fit the cabinet width; chassis units must be quoted with S120 Cabinet Modules integration
12blockA motor cable over 50 m needs a motor reactor, and 150 m is the maximum
13blockLead time is the longest of the Line Module and the motors, plus the cabinet build, and must fit the weeks the customer needs
14approval, then blockDiscount authority: a sales engineer can give 10 percent; the maximum is 20 percent, or 30 percent on a quote of EUR 100,000 or more

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a SINAMICS S120 drive line-up quote for a fictional machine builder, with the total price it expects. Before the quote goes out, the agent sends it to Predictika’s validator, which checks it against Motor Module current, infeed and DC bus, control, safety, mechanics, lead time and discount rules, compares the total the agent states with the one it computes, and returns a verdict with every reason.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. A drive line-up quote for a machine builder: one Siemens SINAMICS S120 Active Line Module 16 kW booksize. Total price €10,190.00. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with one finding, all in one answer. At least one SIMOTICS motor needs more rated current than its Motor Module delivers; choose a larger Motor Module for that axis.
    6. 
      
  6. The validator returned one blocking finding 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 motor current checked against the Motor Module on every axis, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the module 1 to Single Motor Module 5 A and the stated total as to 10,260.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. The validator also returns the line-item quote. It starts with Active Line Module 16 kW booksize with AIM and Slot 1: Single Motor Module 5 A; the other two lines are on screen.
    13. 
      
  13. The earlier finding is cleared, and the validator's total, €10,260.00, matches the quote.
    14. 
      
  14. One problem caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    15.
