Frequently Asked Questions

What communication buses are available on HCS01.1E-W0008-A-03-B-ET-EC-PB-L3-NN-FW?

The controller offers both MultiEthernet for modern Ethernet networks and PROFIBUS for legacy fieldbus integration. This dual-bus approach eases phased upgrades and allows coexistence with older PLC systems while migrating control strategies.

How does STO safety function on HCS01.1E-W0008-A-03-B-ET-EC-PB-L3-NN-FW operate?

Safe Torque Off disconnects the drive’s ability to generate torque when safety inputs are asserted, preventing motion during hazards. Implement STO as part of a larger functional safety strategy and validate wiring and response times during commissioning.

Which encoder interface is provided on HCS01.1E-W0008-A-03-B-ET-EC-PB-L3-NN-FW?

The drive supports IndraDyn Hiperface and EnDat encoder interfaces, supplying high-resolution feedback and enhanced diagnostics for closed-loop control. High-fidelity feedback reduces overshoot and improves positional repeatability in coordinated motion tasks.

How does the dual-bus capability affect network architecture for HCS01.1E-W0008-A-03-B-ET-EC-PB-L3-NN-FW?

Dual-bus capability requires IP and fieldbus planning so that Ethernet and PROFIBUS segments are appropriately segregated yet synchronized where necessary. Use gateways deliberately and minimize protocol translation in the motion-critical loop to maintain deterministic behavior.

What cooling practices best support HCS01.1E-W0008-A-03-B-ET-EC-PB-L3-NN-FW in panels?

Provide sufficient cabinet ventilation and ensure the blower’s intake is unobstructed to maintain component temperatures. Schedule proactive blower inspections and clean air pathways to prevent performance degradation over long production runs.
