Troubleshooting HMI Integration programs for Motor Control in Inovance's InoProShop / AutoShop benefits from a systematic diagnostic process and a clear understanding of likely failure modes. This guide provides a repeatable path from observed symptom to evidence, hypothesis, controlled test, and documented correction.
Start by recording the controller model, firmware, InoProShop / AutoShop version, task state, active faults, I/O status, and the exact conditions that reproduce the problem. Preserve the original project and collect diagnostic evidence before changing logic.
Common challenges in Motor Control systems include soft start implementation, overload protection, and speed ramping. When implemented with HMI Integration, additional considerations include additional cost and complexity, requiring specific diagnostic approaches. Inovance's diagnostic tools in InoProShop / AutoShop provide powerful capabilities, but knowing exactly which tools to use for specific symptoms dramatically improves troubleshooting efficiency.
This guide walks through systematic troubleshooting procedures, from initial symptom analysis through root-cause verification and corrective-action testing. It explains how to use relevant InoProShop / AutoShop diagnostic features and interpret system behavior in a Motor Control context without assuming that one symptom always has the same cause.

Inovance Function Design:
InoProShop strongly favours function-block reuse via the Library Manager — Inovance ships standard libraries for motion, drives, HMI, OPC UA, and industry-specific applications (lithium-battery, EV, elevator). AutoShop reuse is open-coded via P-label subroutines. OEM machine-builders increasingly default to InoProShop / AM600 to access the FB libraries.
Common Challenges and Solutions:
1. Managing starting current within supply limits
- Solution: HMI Integration addresses this through User-friendly operation.
2. Coordinating acceleration with driven load requirements
- Solution: HMI Integration addresses this through Real-time visualization.
3. Protecting motors from frequent starting (thermal cycling)
- Solution: HMI Integration addresses this through Remote monitoring capability.
4. Handling regenerative energy during deceleration
- Solution: HMI Integration addresses this through Alarm management.
Safety Considerations:
- Proper machine guarding for rotating equipment
- Emergency stop functionality with safe torque off
- Lockout/tagout provisions for maintenance
- Arc flash protection and PPE requirements
- Proper grounding and bonding
Performance Metrics:
- Task and I/O timing: Record minimum, average, and maximum values under a defined test load
- Accuracy: Define an acceptable tolerance and compare it with calibrated reference measurements
- Throughput: Count completed cycles over a fixed interval and record rejected or incomplete cycles
- Fault response: Measure detection, safe-state, alarm, and recovery behavior for each test case
- Resource use: Record memory, communications load, and diagnostic-buffer behavior
