# Open Questions for Cédric
|
|
|
|
## Table interface
|
|
|
|
- Confirm KBSI-240D opto-isolated interface or replacement.
|
|
- Confirm ordered BiSS-C table/arm encoder frame timing, CRC/status bits, RS422 transceiver/pinout, shielding, and startup/error handling.
|
|
- Confirm whether the table drive or command path changes electrically.
|
|
|
|
## Spindle / AK60
|
|
|
|
- Define AK60 runtime command and telemetry path; freeze CAN topology, IDs, frame rates, stale-frame timeout, startup behavior, and error isolation.
|
|
- Define command scaling for velocity, direction mapping, enable/disable, fault reset, ramp-to-zero / live-reversal policy, and safe stop behavior.
|
|
- Define telemetry subset: actual RPM, actuator state/error, bus/supply voltage, torque/current if available, motor/drive temperature if available.
|
|
- Export final AK60 commissioning parameters with each machine software release.
|
|
- Define spindle enable/fault I/O and the hardwired AK60 power-removal path through HOA + safety chain; prove E-stop/power-loss behavior on bench.
|
|
|
|
## Z-axis / force actuator
|
|
|
|
- Confirm SV2A-2150 torque/current command mode and scaling.
|
|
- Confirm enable/fault wiring and Iq/current monitor path.
|
|
- Define Z limit-switch / hard-stop wiring into safety chain.
|
|
- Define NC 24 VDC brake coil driver and brake-engaged diagnostic feedback.
|
|
|
|
## Cross-cutting
|
|
|
|
- Select safety relay model.
|
|
- Confirm KWR75B-CAN frame map, byte order, scaling, status bits, and update rate.
|
|
- Confirm final serial/protocol wire format.
