Kollmorgen SAM-DA-400-07N-P4N-E – 400 VAC Analog Servo Drive for Reliable Motion Control

The Kollmorgen SAM-DA-400-07N-P4N-E is a 400 V class servo amplifier built for dependable speed/torque control in industrial machinery. It typically suits retrofits or expansions where an analog ±10 V command is already in place, and in many cases the “07N” code denotes a 7 A current class that pairs nicely with mid-frame servo motors. One thing I appreciate is how forgiving this series is in mixed-technology lines—legacy analog references, resolver feedback, and straightforward I/O keep integration clean without forcing a full controls redesign.

Key Features

• 400 VAC class input – Designed for 3-phase 380–480 VAC mains; ideal for European and international plants running 400 V networks.
• Analog command (±10 V) – Simple velocity/torque loop control from a PLC or motion card without rewriting the whole control architecture.
• Resolver feedback (P4N option) – Robust feedback for harsh environments; it tends to tolerate electrical noise better than some digital encoders.
• 7 A current class – Suits many mid-size axes in packaging, printing, and material handling where continuous loads are moderate but dynamic response is still important.
• Practical protection features – Overcurrent, overvoltage, and overtemperature protections help safeguard the drive and motor during faults or power events.
• Regenerative handling – Supports external braking resistor for deceleration energy, which is handy on fast indexers and short-stroke actuators.
• Service port for setup – A serial service connection is typically provided for parameterization, backups, and diagnostics.
• Straightforward I/O – 24 V digital inputs/outputs for enables, fault resets, motor brake control, and limit/home signals in most setups.

Technical Specifications

Application Fields

You’ll typically find this model driving mid-size axes where uptime matters more than new-to-the-world features: horizontal form-fill-seal machines, turret indexers, unwind/rewind stands, labeling lines, light-duty CNC positioning, and automated test stands. From my experience, it’s especially useful when you need to keep an existing analog motion architecture but still want modern protections and stable tuning.

Advantages & Value

• Reliability – Mature design with protective fault handling reduces unplanned stops in many cases.
• Compatibility – Works with existing ±10 V motion cards and PLCs, plus resolver-equipped motors already on the machine.
• Cost control – Avoids a full controls refresh; wiring changes are minimal compared to switching to a completely new bus-based platform.
• Support ecosystem – Cables, filters, and braking resistors are readily available; documentation is straightforward for maintenance teams.

A maintenance manager in a beverage-packaging plant told me they swapped a failed analog drive with this unit over a weekend—motor resolver stayed the same, parameters were close, and they were back in production before Monday’s startup.

Installation & Maintenance

• Cabinet standards – Mount on a grounded metal backplate in a ventilated cabinet; keep ambient at or below 40°C. Allow clearance above/below the heatsink for airflow.
• Wiring – Use shielded motor/feedback cables; bond shields 360° at the drive. Follow proper PE grounding. Size line fusing and contactors per the 400 V class rating.
• Regen resistor – For fast deceleration, connect an external braking resistor sized to the axis inertia and duty cycle. Keep it away from heat-sensitive components.
• Tuning – Start with conservative loop gains; many technicians use a step-test at low speed, then raise gains until response is crisp without audible oscillation.
• Routine checks – Inspect fan/airways quarterly, re-torque power terminals after thermal cycling, and back up parameter files after any change.

Quality & Certifications

• CE and UL conformity for industrial environments (typical for this series)
• RoHS-compliant construction where applicable
• Manufacturer warranty as per Kollmorgen policy; our supplied units include a 365-day warranty

Suggested Supporting Components

• Kollmorgen AKM series servo motors with resolver feedback (match the motor’s continuous torque/current to the 07N class).
• External braking resistor sized to the application’s kinetic energy (short, frequent decel moves typically require higher wattage).
• EMI line filter and proper line reactor for noisy mains or long cable runs.
• Shielded motor power and feedback cable sets with robust 360° shield terminations.
