The Real Cost of Ignoring Small Drive Issues



Small problems become big failures. Here’s how to stop the snowball.

In industrial environments, drives keep motors running, production lines moving, and processes stable. Too often, small drive issues get brushed aside as minor annoyances. The reality: a slight vibration, intermittent fault, or faint smell of overheating can escalate into catastrophic failures, unplanned downtime, and major costs.

At Delta Automation, we see this story play out all the time. Here’s why addressing small issues early protects uptime and budget.

Minor Symptoms, Major Consequences

Drives rarely fail without warning. They send signals—sometimes subtle—that something isn’t right:

  • Intermittent error codes often point to failing capacitors, loose connections, or power supply problems.
  • Unusual noises or vibrations can indicate worn bearings, fans, or cooling components that lead to heat build-up.
  • Overheating or a burnt odor may stem from dust buildup, clogged fans, or aging power components—precursors to shutdowns.
  • Slow response or inconsistent performance can flag early logic, I/O, or communication issues.

Fixing these early often costs a fraction of a full replacement—or the ripple effects of extended downtime.

How Small Problems Snowball

  1. Heat cascades through the system. A failing fan compromises cooling and stresses IGBTs, capacitors, and boards.
  2. Unplanned downtime multiplies costs. A minor fault that trips a line can derail schedules and service levels.
  3. Emergency replacements are expensive. Rush buys mean premiums, longer lead times, or ill-fitting substitutes.
  4. Collateral damage spreads. A malfunctioning drive can strain motors, gearboxes, and downstream equipment.

The Hidden Costs of Waiting

Typical early fixes

Fan replacement, capacitor swap, cleaning, re-termination — often $300–$600.

Major failure scenario

Drive replacement, reprogramming, re-commissioning — commonly $5,000–$10,000+, plus downtime.

Downtime impact

Even one hour of a mid-size line down can cost thousands of dollars in lost production.

Waiting feels like saving until the hidden costs surface all at once.

Why Regular Drive Service Pays Off

  • Extends equipment life by addressing heat, dust, and wear before they cascade.
  • Reduces emergency calls through planned inspections and parts refreshes.
  • Improves reliability for steadier throughput and fewer mid-shift surprises.
  • Supports sustainability by repairing instead of scrapping—less waste, more lifecycle value.
