Frequently Asked Questions
What are the wiring and drive requirements for a Hiperface multiturn capacitive encoder?
Hiperface uses a 1 Vpp sin/cos analog track plus an RS-485 parameter channel; IndraDrive control sections provide a native Hiperface evaluation (ENS). Use shielded Rexroth encoder cables and follow the pinout to avoid noise and compatibility issues.
How should I size the drive for the specified peak current and torque?
Dimension the drive to supply the motor’s peak current while respecting the speed-torque curves of the 0300 winding; verify the DC-bus/feed variant because max torque depends on supply topology. Use the Rexroth MSK speed-torque charts for the 0300 winding as your acceptance check.
What are the practical benefits of a capacitive encoder versus optical on this motor?
Capacitive encoders are tolerant to dust/oil, vibration, and temperature swings and typically have lower current draw and longer life than LED-based optical types—helpful in packaging and machining environments. That robustness reduces drift and maintenance for high-duty B2B lines.
What cable and installation rules matter for high-current runs to this frame size?
Follow VDE/EN machinery wiring tables and Rexroth current-carrying guidance to choose cross-sections and installation methods; bundling or higher ambient temps lower permissible current. For IndraDrive systems, use shielded RKL power/encoder cables to limit EMI and bearing currents.
How should I evaluate the 70 Nm holding brake for a vertical axis?
Holding brakes are for static holding and E-stop retention, not dynamic stopping—check load torque at standstill (gravity + friction) and include a safety factor so it remains < 70 Nm. Use the drive for controlled stops; the brake engages once motion ceases.
