YASKAWA JAMMC-SV150A – Servo Control Circuit Board | Σ-Series AC Servo Drive Platform
Engineering Background
The YASKAWA JAMMC-SV150A is a dedicated servo control circuit board engineered for YASKAWA’s Σ-Series (Sigma) AC servo drive systems. Designed and manufactured in Japan to YASKAWA’s stringent industrial-grade standards, this PCB serves as the core motion-control intelligence within the servo amplifier unit, managing real-time current regulation, encoder feedback processing, and drive protection logic.
Product Positioning
Targeted at maintenance engineers, OEM integrators, and MRO procurement teams, the JAMMC-SV150A is the authoritative replacement board for failed or degraded servo amplifier control cards. It eliminates the need for full drive replacement, significantly reducing downtime costs and capital expenditure in production-critical environments.

System Architecture & Signal Flow
Within the YASKAWA Σ-Series servo amplifier, the JAMMC-SV150A occupies the control layer between the host controller (PLC/CNC) and the power stage (IGBT module). Signal flow: Host Command (MECHATROLINK / Pulse Train) → JAMMC-SV150A Control Board → PWM Gate Drive Signals → IGBT Power Module → Servo Motor. The board also processes encoder feedback from the motor, closing the position/velocity/torque control loops in real time.

Technical FAQ
Q: Is the JAMMC-SV150A compatible with all YASKAWA Σ-Series drives?
A: Compatibility depends on the specific amplifier model and revision. Please provide your drive model number before ordering. Our team will confirm fit.
Q: Does this board require parameter initialization after installation?
A: In most cases, parameters are stored in the drive’s separate memory unit (EEPROM/parameter card). The JAMMC-SV150A itself does not require re-parameterization, but a drive self-check (Fn000 series) is recommended post-installation.
Q: What warranty is provided?
A: We offer a 90-day functional warranty on all tested units. New/surplus units carry standard OEM warranty terms where applicable.
Q: Can you supply multiple units for a production line overhaul?
A: Yes. Contact us for volume pricing and scheduled delivery programs tailored to MRO and OEM procurement requirements.
