Solving the Discontinued Hardware Crisis

The Jetter JM-600 series was designed for deterministic, high-speed motion control in applications where cycle time tolerances are measured in microseconds. Facilities running packaging lines, press feeders, or multi-axis assembly cells on this platform built their process logic around the JetControl instruction set and the specific interpolation behavior of the JM-620-480-SB1. That logic does not transfer to a different motion controller without rewriting cam profiles, synchronization routines, and position registers.

The industrial automation market has moved toward EtherCAT-based distributed servo drives, and Jetter's own current portfolio reflects that shift. The JM-600 series has no direct modern successor that accepts the same configuration without software migration. For a plant manager facing a failed unit, the realistic options are: locate a verified spare, or commit to a platform migration that will consume engineering resources for 6 to 18 months.

How to extend your JetControl system life by 5 to 10 years:

Condition & Reliability Assurance

Obsolete servo controllers present specific failure modes that differ from standard wear. Our 5-step QA process for the JM-620-480-SB1 addresses the failure patterns most commonly observed in units that have been in storage or removed from service:

1. Electrolytic capacitor inspection. Capacitors in the power supply and DC bus sections are the primary age-related failure point in servo controllers of this generation. Each unit is inspected for capacitor bulging, electrolyte leakage, and ESR deviation. Units with degraded capacitors are either recapped with equivalent-specification components or rejected.
2. Firmware version verification. The firmware version is read and recorded before any other intervention. Units are not flashed or modified unless explicitly requested by the customer. The original firmware state is preserved and documented.
3. RFQ terms review: Commercial terms are confirmed during RFQ review based on model, condition, documentation, quantity and destination.
4. Functional power-on test. Units are powered and tested for correct initialization, fault-free startup, and communication response where test fixtures permit. Units that fail to initialize cleanly are quarantined and not sold as functional.
5. Packaging for long-term storage. Units intended for cold-spare inventory are packaged in anti-static bags with desiccant, sealed, and labeled with inspection date and firmware version. This extends reliable storage life by a minimum of three years beyond standard packaging.

Key Features for System Maintenance

• Drop-in replacement. The JM-620-480-SB1 is a direct hardware replacement for the same part number in any JetControl installation. No mechanical modification is required.
• No reprogramming required. Provided the replacement unit carries the same firmware version as the failed unit, the JetControl CPU will recognize it without parameter re-entry. Axis configuration is stored in the CPU, not the servo module.
• Avoids engineering reconstruction costs. A verified spare eliminates the need to engage a systems integrator for platform migration. The cost difference between a spare unit and a migration project is typically two to three orders of magnitude.

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

How do I know the unit is genuine and not a counterfeit?
All units are inspected for OEM labeling consistency, PCB markings, and component date codes. We do not source from markets known for counterfeit industrial components. A certificate of inspection is available on request.
