Application-Specific FAQ
Q: Is the CPX8541S/F4 compatible with third-party servo motors?
A: Yes, with proper motor data configuration in C3 ServoManager. Parker provides a motor database; unlisted motors require manual parameter entry and test runs.
Q: Can this drive operate in torque-control mode for tension applications?
A: Yes. The COMPAX-S supports position, velocity, and torque control modes, selectable via software or digital inputs.
Q: What is the maximum cable length between drive and motor?
A: Parker recommends ≤25 m for standard cable; up to 50 m with optional output choke to limit dV/dt stress on motor windings.
Q: Does the /F4 variant support absolute encoders?
A: The F4 feedback option is optimized for resolver and incremental encoder. For absolute multi-turn encoder support, consult the /F5 or /F6 variants.
Q: Is a safety function (STO) available on this model?
A: STO availability depends on the specific hardware revision. Please provide your serial number for confirmation, or contact our technical team.
