Frequently Asked Questions

How does regenerative operation affect plant energy use and braking hardware sizing?

It pushes deceleration energy back to the mains, reducing brake resistor load and heat in the cabinet. Bosch Rexroth’s HMV01 “R” variants are designed for regeneration on a 750 V DC bus used with IndraDrive power sections.

For multi-axis CNC/robot cells, how do I size the DC bus when several inverters share one supply?

Sum peak/continuous inverter demands and confirm intermediate-circuit capacity and bus voltage limits to prevent undervoltage during regen and overvoltage on rapid stops. Rexroth HMV sizing tables show intermediate-circuit data and 750 V regulated bus behavior for shared-bus systems.

How do IP20 and 0…+40 °C ambient affect enclosure design on factory floors?

Use a protective cabinet and consider heat-exchanger or air-to-air units if ambient rises above 40 °C to keep the electronics in spec. IndraDrive documentation specifies IP20 units for control cabinets and gives thermal planning rules.

What line components mitigate harmonics and protect the HMV supply on 380–480 V networks?

Install approved mains chokes/transformers per the project planning manual to limit THDi and inrush, and ensure proper earthing for EMC. Rexroth provides transformer and choke selection as part of IndraDrive system accessories.

What commissioning behaviors should I expect on first power-up and during faults?

Expect DC-bus precharge, quick-discharge, and status messages (e.g., VM.A0502/A0520/A0800) that indicate charging, discharge, and operating states. Use these diagnostics along with the project planning manual to validate wiring and remedy faults.
