The Jetter JM-108 (Part No. 10000749, Rev 02A) is a high-performance digital servo drive designed for precision motion control. Engineered by Jetter AG, this compact drive is typically integrated into the JetMove series, providing robust torque, speed, and position control for synchronous servo motors. It is widely utilized in high-speed industrial machinery, such as labeling equipment, packaging lines, and automated assembly systems, where consistent motion profiling is critical.

Mechanical Installation Requirements

• Mounting Method: Designed for vertical mounting within a control cabinet on a standard mounting plate. Ensure the drive is installed upright to allow for natural chimney-effect cooling.
• Clearance: Provide at least 100mm of vertical space above and below the unit. This is essential for the cable entry and the heat sink’s airflow requirements.
• Thermal Management: Maintain a lateral gap of at least 20mm from adjacent drives. If multiple drives are mounted in a row, consider the total heat dissipation and ensure the cabinet is properly ventilated with filtered air.

 

Electrical Wiring & Grounding

• Terminal Definitions: Power and motor connections are typically handled via pluggable spring-clamp or screw-terminal connectors. The front panel features clearly marked terminals for 24VDC control supply, DC-bus power, and motor phases (U, V, W).
• Wire Gauge: Use shielded power cables for the motor connection (minimum 1.5mm² recommended) and shielded twisted-pair cables for encoder feedback to minimize noise coupling.
• Grounding Norms: The heat sink of the JM-108 must be connected to the cabinet’s main grounding bus using a low-impedance connection (e.g., a short copper braid). Ensure cable shields are grounded directly to the drive’s dedicated PE terminal to maximize EMI immunity.

 

Configuration & Communication

• Address/Node ID: Node addressing is typically configured via internal software parameters or physical rotary switches (if equipped) to integrate the drive into the fieldbus network.
• Startup: Parameterization is performed using the Jetter “JetSym” or “JetMove” configuration software. The drive must be commissioned by defining motor type, encoder resolution, and current loop gains.
• Baud Rate: For CANopen configurations, the baud rate is software-selectable (typically up to 1 Mbps depending on bus length).

 

Frequently Asked Questions (Q&A)

Q: What does the “Rev 02A” designation signify? A: The revision code indicates the specific hardware iteration of the JM-108. Always ensure your software version is compatible with this hardware revision, as firmware feature sets may vary between releases.

Q: Can I use this drive with non-Jetter motors? A: While the JM-108 is optimized for Jetter servo motors, it can be adapted to other brushless AC motors, provided the motor parameters (pole count, encoder type, and phase sequence) are correctly identified and configured in the software.

Q: Why is the “Error” LED flashing? A: A flashing error LED typically indicates a drive trip. Common causes include under/over-voltage, short circuit at the motor output, or a loss of encoder signal. Check the error register in the JetSym software for the specific fault code.

Q: Is the DC-bus link shareable? A: Yes, the JM-108 supports DC-bus coupling with other JetMove drives, allowing energy exchange during braking phases, which can significantly improve energy efficiency.
