Kollmorgen AKD-B00607-NCA
Product Type: Digital AC Servo Drive (with Internal Brake Chopper)
Product Brief:
The AKD-B00607-NCA is a Kollmorgen AKD servo drive. “B” = AKD-B (standard format, slightly larger than AKD-P). “00” = 480 VAC three-phase input. “6” = fieldbus configurable. “07” = 7 A continuous. “NCA” = N (EtherCAT), C (with internal brake chopper), A (standard I/O).

Functional Features:
- Internal brake chopper — the “C” in NCA confirms an integrated braking transistor and resistor. This eliminates the need for an external dynamic brake resistor for standard deceleration profiles.
- Identical motion control features to AKD-P02407-NBCN-0000 and AKD-POO607-NBA
- Kollmorgen Automation Engine (KAE) with motion profiling, electronic gearing, camming
- EtherCAT with DC synchronization for multi-axis coordinated motion (< 1 µs jitter)
Key Difference from AKD-POO607-NBA:
| Feature | AKD-POO607-NBA | AKD-B00607-NCA |
|---|---|---|
| Brake Chopper | NOT included (external resistor required) | INCLUDED (internal) |
| Format | AKD-P (compact) | AKD-B (standard) |
| Weight | ~1.2 kg | ~1.3 kg |
Applicable Industries:
- Same as AKD-POO607-NBA and KD-P02407-NBCN-0000
- Preferred when an external brake resistor cannot be installed (e.g., enclosed cabinets, hazardous areas)
Installation Requirements:
- Same as AKD-POO607-NBA
- No external brake resistor needed (internal chopper handles standard loads up to 500 W regenerative power)
- For high-inertia loads (> 500 W regen), an external resistor is still recommended
Usage Notes:
- The internal brake chopper is rated for ~500 W continuous regenerative power — verify your application’s deceleration energy does not exceed this
- If regenerative power exceeds 500 W, connect an external brake resistor across the brake terminals (+BRK, −BRK) regardless of the internal chopper
