Fanuc alarm SV0468: HI HRV SETTING ERROR (AMP)
αi/βi Servo (SV0xxx) · Fanuc 0i-D
What it means
High-speed HRV control was enabled for an axis on an amplifier that does not support it. High-speed HRV demands specific current-control hardware and sufficient processing bandwidth per amplifier. Either lower the HRV level in parameters or use an amplifier variant qualified for the desired HRV level.
Likely causes
- HRV level parameter set above amplifier capability
- Multi-axis amplifier sharing bandwidth across unsupported combination
- Amplifier order/specification not matching machine build sheet
