🔍 Product Overview
The Siemens 6RA70 DC Drive series has been the industry benchmark for electrical drives and control for over two decades. The model 6RA7018‑6DV62‑0 is a microprocessor‑based, four‑quadrant converter designed to power and regulate DC motors with exceptional accuracy. It is part of the SIMOREG DC‑Master line, which covers a power range from 15 A to 3000 A (single unit) and can be paralleled for even higher currents. This specific DC Drive Unit is rated for 400 V three‑phase AC input, delivers 420 V DC output, and handles a continuous armature current of 30 A, making it ideal for medium‑power electrical drive applications.
All control, monitoring, and auxiliary functions are implemented in software – no additional hardware is required for parameterization. The integral parameterization unit (PMU) and the free PC‑based commissioning tool SIMOVIS make start‑up fast and straightforward. This Siemens 6RA70 DC Drive is therefore a true “plug‑and‑work” electrical drive that reduces engineering time and helps you get your machinery up and running in the shortest possible time.

⚡ Key Features of the 6RA7018‑6DV62‑0 DC Drive Unit
Every element of this Siemens 6RA70 DC Drive has been engineered with real‑world production in mind. Below are the standout characteristics that make it a preferred choice for electrical drives and control projects:
🗜️ Compact Design
The unit integrates armature and field converters in a single, space‑saving enclosure. Its small footprint (≈ 385 × 265 × 283 mm) saves valuable cabinet space.[reference:0]
🔧 Integrated Field Unit
A built‑in field rectifier supplies up to 325 V DC / 5 A, eliminating the need for an external excitation module and simplifying system wiring.[reference:1]
🧵 Built‑in Winder Software
Standard technology software (S00 option) includes tension control, dancer position regulation, and winder/unwinder functions – ideal for converting, paper, and wire industries.[reference:2]
🌐 Multi‑protocol Connectivity
Optional communication boards (CBP for PROFIBUS‑DP, CBC for CAN) allow seamless integration into any automation hierarchy. RS‑232 and RS‑485 ports come standard.[reference:3]
📈 PID & Closed‑Loop Control
Dual 16‑bit microprocessors execute speed, current, and field control loops. The integrated PID controller can be freely configured for process variables such as pressure or flow.[reference:4][reference:5]
🚀 Easy Start‑up Wizard
A guided commissioning assistant (PMU + SIMOVIS) walks you through motor identification, optimisation, and parameter setting – no specialised programming skills needed.[reference:6]
🖥️ Large Control Panel
A bright, multi‑line PMU display provides clear status readouts and access to all drive parameters directly at the device – no additional HMI required.[reference:7]
🛡️ Rugged, Maintenance‑Friendly
Plug‑in terminals for signal connections, easy‑to‑swap electronic boxes, and flash‑EPROM firmware ensure high uptime and simple servicing.[reference:8]

❓ Frequently Asked Questions
Q: What is the input voltage tolerance of the 6RA7018‑6DV62‑0?
The drive accepts a three‑phase supply of 400 V AC with a tolerance of +15 % / –20 %. It also operates at 50 Hz or 60 Hz without derating. For other supply voltages (575 V, 690 V, 830 V, 950 V), refer to the broader 6RA70 series.[reference:9]
Q: Can this DC Drive Unit operate in all four quadrants?
Yes. The 6RA7018‑6DV62‑0 employs a bidirectional bridge configuration (B6) A (B6) C, which allows motoring and regenerating operation in both directions of rotation. This makes it suitable for applications requiring rapid braking or reversing.[reference:10]
Q: How is the drive commissioned and programmed?
Commissioning is performed via the built‑in PMU panel or through the free SIMOVIS PC software. A start‑up wizard guides you through motor data entry, self‑identification, and optimisation. The BICO parameterisation concept allows custom interconnections without additional programming tools.[reference:11][reference:12]
Q: Is overload protection included?
Yes. The drive can handle an overload of 1.5 × rated DC current. The exact permissible duration depends on the preceding load cycle and ambient temperature. The manual DA21 provides detailed overload curves for system design.[reference:13]
Q: What communication protocols are supported?
The base unit provides an RS‑232 and an RS‑485 port. With optional plug‑in boards, PROFIBUS‑DP (CBP module) and CAN bus (CBC module) can be added. This enables full digital integration with SIMATIC PLCs and third‑party controllers.[reference:14][reference:15]
