Application-Specific FAQ
Q: Is the CR1QA-761 compatible with older MELFA RV-1A / RV-2A robot arms?
A: No. The CR1QA series is designed for the current-generation RV-2F/4F/7F and RH-3FH/6FH platforms. Legacy RV-1A/2A arms require the CR750-Q or CR750-D controller.
Q: Can the CR1QA-761 control a 7th external axis (e.g., a linear track)?
A: Yes. An additional servo amplifier module can be added to control one external axis (e.g., a positioner or linear slide), coordinated in the robot’s motion program.
Q: Does this controller support EtherNet/IP or PROFINET for integration with Allen-Bradley or Siemens PLCs?
A: EtherNet/IP and PROFINET are supported via optional communication option cards. Please specify your PLC brand when requesting a quote so we can confirm the correct option card part number.
Q: What is the warranty period?
A: Konmask.com provides a 12-month warranty against manufacturing defects. Warranty claims are processed via our RMA procedure; replacement or repair is completed within 15 business days.
Q: Can you supply the complete robot cell (arm + controller + software)?
A: Yes. Contact us with your application requirements (payload, reach, cycle time, environment) and we will configure a complete MELFA system BOM with competitive pricing.
