: Internal EEPROM corruption. Attempt a hard factory reset. If the error persists, the control board requires replacement.
The LE-30CTA manual highlights several safety and operational tips:
Realizes fine-tuned control with a minimum trigger adjustment time of 25 ns. Manual Installation & Safety Guidelines
Tighten screws within the specified torque range to avoid short circuits or operational failures. mitsubishi tension controller le 30 cta manual exclusive
To prevent EMI (Electromagnetic Interference), shielded cables are mandatory for load cell connections. 2. Configuration and Calibration
The Mitsubishi LE-30CTA and LE-40MT series have been officially designated for replacement with the model. Key considerations when planning a migration:
For replacing LE-40MT or LE-30CT series controllers with the LE7-40GU, Mitsubishi offers the , which facilitates physical and electrical integration. : Internal EEPROM corruption
Use for terminal block connections, tightened to a torque of 0.5 to 0.8 N·m .
Must be installed on a flat surface inside a shielded conductive control box to ensure safety and minimize electrical noise. Wiring Precautions:
For new projects, Mitsubishi recommends transitioning to a current model like the for full technical support, software, and modern features such as Ethernet/IP connectivity and advanced autotuning. However, the LE-30CTA remains an excellent choice for operating and maintaining existing machinery. Use for terminal block connections
: With material not threaded through the machine, measure voltage between the white and green wires of the tension detector. If the voltage exceeds ±120mVDC, the selected tension detector is inappropriate (tare weight ≥80% of rated value). Check detector roller mass and replace with appropriate detector if necessary.
: Ensures uniform thickness and flatness in strip coating and slitting lines for steel or aluminum. Manual and Documentation Resources
Linear counter, ring counter, sampling, and periodic pulse functions Response Time Minimum 25 ns for ON/OFF adjustments Safety Features
If your tension readings are "fluttering," check the distance between your signal cables and high-voltage motor wires. The manual recommends a minimum clearance of 200mm.
