Kollmorgen CB10661-MZ
Product Series: Kollmorgen SERVOSTAR CD (Compact Drive) Family — 230 VAC Class
Product Brief: Digitally controlled 3-phase PWM servo amplifier for brushless (BLDC/PMSM) and brushed DC servo motors. Designed for stand-alone or multi-axis machine control with SERCOS optical fiber interface for deterministic real-time communication with a motion controller. CB10661-MZ is a 230 VAC input, medium-current variant of the CD series.
Detailed content
Input Supply Voltage (Power): 208 – 230 VAC 3Φ (some CD units accept 115/230 VAC 1Φ — CB10661 is 3Φ 230 V class)
DC Bus Voltage (Nominal): ≈ 325 VDC
Continuous Output Current (RMS): 6.0 A (CD10661 base model — CB10661-MZ shares CD10661 power stage; certain references cite 13 A cont / 26 A pk for CD10661-13 variants — verify nameplate)
Peak Output Current (RMS, 0.5 s): 12 – 26 A (model-dependent; CD10661-13 = 26 A pk)
Control Logic Supply: +24 V DC (18–30 VDC), isolated
Communication Interface: SERCOS Interface (IEC 61491) — optical fiber ring (transmit/receive)
Analog / Digital I/O: ±10 V analog command input (when used in standalone analog mode — not primary in SERCOS config), programmable digital I/O, resolver/encoder feedback interface onboard
Supported Feedback: Resolver (standard), Incremental Encoder (TTL/Line Driver), SinCos 1 Vpp (depends on feedback option card fitted)
PWM Switching Frequency: 8 kHz / 16 kHz (selectable via parameter)
Protections: Overcurrent, over/undervoltage (UV trip ≈ 90 VDC bus, OV trip ≈ 430 VDC bus), I²t motor thermal model, short-circuit, heatsink overtemperature
Dimensions (H × W × D): 244 mm × 100 mm × 163 mm (typical CD book-style)
Weight: ≈ 2.6 kg
Cooling: Forced convection (internal fan) or convection in ventilated cabinet
Protection Class: IP20 (panel mount only)
Operating Temperature: 0 °C to +45 °C (full rated); derating to +55 °C
Certifications: CE, UL, cULus, TÜV
Applicable Industries: Legacy high-speed packaging lines, printing press drives, textile machinery, paper converting, specialty machine tools originally designed around SERCOS motion buses
Installation Requirements: Mount vertically in grounded enclosure with ≥ 50 mm top/bottom clearance; connect 3Φ 230 VAC via isolating contactor + line filter; bond PE terminal; connect SERCOS fiber; set node address via DIP switches before ring closure.
Usage Notes: CB10661-MZ is obsolete / legacy — replacement is AKD or AKD2G with EtherCAT/Profinet; SERCOS master/ring must be properly terminated; verify actual continuous current rating on unit nameplate (CD10661-06 = 6 A, CD10661-13 = 13 A); regen resistor may be required for high-inertia deceleration — check parameter for external brake resistor value.
