The R911306439 (HMD01.1N-W0012) is a Rexroth drive controller designed for single and multi-axis motor and motion control tasks in industrial automation systems. It utilizes an internal air cooling method with an integrated blower and supports operation up to a 12 A effective peak current. The device accommodates a 24 V control voltage input (±20%) and operates within a rated input voltage range of 254 V DC to 750 V DC. Output parameters include a three-phase AC voltage from 0 to 530 V, an output current up to 6.9 A, and frequency range of 0 Hz to 800 Hz. The unit features modular construction with a separable control and power section and incorporates configurable interfaces and optional modules. Designed for copper field wiring and environments up to 40°C ambient temperature, the drive controller has a mass of 5.5 kg and a short circuit current rating of 42,000 A rms. Power consumption at rated control voltage is 17 W and power dissipation at continuous current is 2 x 95 W.

Frequently Asked Questions

What is the significance of the continuous vs. effective peak current rating on the HMD01.1N-W0012?

Continuous current defines what the drive can sustain indefinitely without overheating; the “effective peak” (12 A) allows short bursts (typically <60 s) for load surges or acceleration. Operating too long at or near peak current forces thermal derating or trigger of protection mechanisms.

How does the DC-bus voltage range (254-750 V) affect system design and safety margins?

A wide DC-bus range gives flexibility to use various rectifier modules or power supplies, but you must ensure upstream components (rectifier, capacitors) are rated for the highest DC level and transient overvoltage. Also, higher DC-bus voltage increases insulation requirements on motor cables and creepage distances.

What does the 0-800 Hz output frequency capability enable in real-world applications?

This range permits precision control over motor speed, especially in applications needing very high speeds (e.g., spindle drives, high-speed conveyors) or fine low-speed control; above standard 50/60 Hz use. But performance (torque, current capacity) may drop at extreme frequencies because of limitations in motor cooling and switching losses.

How should one interpret the Short Circuit Current Rating (42,000 A) for protection system coordination?

The SCCR defines the maximum fault current the device can safely withstand without catastrophic failure; protection devices upstream must have interrupting ratings above this value. Ensuring proper breaker or fuse sizing with appropriate breaking capacity is crucial to protect both the drive and the installation.

What is the meaning of “HMD01.1N-W0012 discharge time 30 minutes after power-off,” and when does it matter?

After you remove DC supply, the internal DC-bus capacitors will hold charge and take up to ~30 minutes to discharge to a safe level; it matters for safe maintenance or servicing to avoid electric shock. Always follow lock-out/tag-out procedures and ensure voltage has dropped before touching internal components.
