Application-Specific FAQ
Q: Is the CR750-02VQ-1 compatible with older MELFA RV-2AJ or RV-6S robots?
A: No. The CR750 series is designed for the current MELFA F-series (RV-2F, RV-4F, RV-7F, RV-13F, RH series). Legacy robots require CR1D or CR2D controllers. Please confirm your robot model before ordering.
Q: Can this controller be integrated with a Siemens S7 PLC via PROFINET?
A: Yes. The CR750 supports PROFINET IO as an optional communication protocol, enabling direct integration with Siemens, Beckhoff, and other PROFINET-compatible PLCs.
Q: What is the maximum cable length between the controller and robot arm?
A: Standard cable sets are available in 5m, 10m, and 15m lengths. Custom lengths up to 30m are available as special orders through Mitsubishi Electric.
Q: Does the CR750-02VQ-1 support force/torque sensor integration?
A: Yes, via the optional force sensor interface unit. This enables compliant assembly, insertion tasks, and contact detection applications.
Q: Is this unit suitable for cleanroom (ISO Class 5) environments?
A: The controller itself is rated IP20 and is designed for installation outside the cleanroom. The compatible MELFA RV-F cleanroom variants handle in-cell requirements.
