Model Analysis (CFG-RD500-P2-NN)

CFG: Configuration (Module type)

RD500: Product Series (RD = Drive, 500 = Power / Platform Level)

P2: Power Level 2 (Medium Power)

NN: Standard Firmware / No Special Customization Basic Information

Alternative model: RD51.2-4B-007-L-A2-FW (Part number: R911200838)

Structure: Book-style / Rack-mounted, single-module integrated drive + control

Dimensions (approx.): 305 × 102 × 432 mm

Weight (approx.): 7.9 kg

Cooling: Air cooling (built-in fan)

Origin: Germany Core parameters

Input voltage: Three-phase AC 200～480V (±10%)

Control mode: Vector control (VC) / V/F control, supporting spindle positioning

Power range: Approximately 7.5～15 kW (corresponding to P2 level)

Output frequency: 0～400 Hz (spindle application can reach 800 Hz)

Overload capacity: 150%/60 s, 200%/10 s

Communication: Standard SERCOS, optional PROFIBUS-DP

I/O: Digital 8 inputs / 6 outputs, analog 2 inputs / 1 output

Function positioning

Positioning: General-purpose frequency converter + spindle servo drive, suitable for machine spindle and ordinary frequency converter load

Control characteristics: Spindle orientation, rigid tapping, speed / position closed loop

Applicable motors: IndraDyn M series spindle motors (MAD, MAF) + standard asynchronous motors

Difference from CDM series: CDM = multi-axis motion controller (without drive); CFG-RD500 = drive + control integration

Typical applications

Machine tools: Machining center spindle, lathe spindle, grinding machine spindle

Automation: High-speed spindle, synchronous drive, tension control

Alternative scenarios: Upgrade of Indramat's old TDM/TDC series drives

Adaptable accessories

Communication cards: SERCOS interface card, PROFIBUS-DP card

Encoders: 1Vpp/TTL spindle encoder, Hiperface absolute encoder

Filters: Power EMC filter, output reactor
