Good Price Panasonic AC Servo Motor MDMA202P1G MDMA2O2P1G IN STOCK

Panasonic MDMA202P1G | MINAS A4 2 kW Medium Inertia AC Servo Motor — 9.55 Nm / 2000 rpm / 17-bit Absolute / IP65

Medium Inertia — Where This Fits in the A4 Lineup

Panasonic's MINAS A4 family covers three inertia classes: low, medium, and high. Medium-inertia motors have a heavier rotor than low-inertia motors — this rotor mass absorbs load variation more gracefully rather than responding to every fluctuation, producing stable, predictable axis behaviour that simplifies gain tuning on machines with moderate mechanical compliance.

The MDMA202P1G at 9.55 Nm continuous torque and 2,000 rpm gives real torque authority over loaded feed axes without needing a gearbox. At 10.6 kg, the motor weight should be factored into axis design calculations — this is not a compact light-duty motor.

Key Specifications

17-Bit Encoder — Absolute and Incremental in One

The G encoder designation identifies a combined absolute/incremental 17-bit encoder at 131,072 ppr. The same motor serves applications requiring true absolute position retention (no homing cycle at power-up, when the A4 driver is fitted with a backup battery) and applications where incremental operation is sufficient — no hardware change required between the two modes.

At 131,072 ppr, the encoder provides fine feedback granularity for stable low-speed operation and precise stop positioning. Absolute position backup requires the lithium battery to be fitted and healthy in the A4 driver — without the battery, the encoder operates in incremental mode only.

Cannon Connector and IP65

The Cannon (MS series) bayonet-locking connectors at both the motor power and encoder cable connections provide secure mechanical retention that resists vibration-induced loosening — relevant for machine tool and robotics applications where the motor environment involves continuous vibration and coolant exposure. IP65 confirms full dust exclusion and water jet protection for the motor body.

Compatible Driver

This motor works with Panasonic MINAS A4 series drivers. For a 2 kW motor, the standard A4 driver match is the MADDT3207 or equivalent in the A4 driver family.

FAQ

Q1: What Panasonic driver is compatible with the MDMA202P1G?

The MINAS A4 series driver MADDT3207 or equivalent in the A4 driver family for a 2 kW motor. Confirm the driver's rated current covers the motor's rated current and verify driver-motor compatibility in Panasonic's A4 motor selection documentation before pairing.

Q2: Does this motor retain absolute position after power is cut?

Yes — when the A4 driver is fitted with a backup lithium battery. Position data is retained through power interruptions via the battery. Without the battery, the encoder operates in incremental mode only and requires a homing cycle at each power-up to re-establish the position reference.

Q3: What is the practical difference between medium and low inertia for this application?

Medium-inertia motors buffer load variation more effectively — the heavier rotor smooths out fluctuations rather than reacting to every change. They are more forgiving to tune on machines with moderate mechanical compliance. Low-inertia motors accelerate faster and suit high-cycle dynamic applications where rapid acceleration response is the priority. For feed axes with moderate load mass variation, medium inertia typically gives more stable behaviour with less gain-tuning effort.

Q4: Is the MINAS A4 series still in production?

The A4 series has been discontinued by Panasonic. The MDMA202P1G is available through industrial distributors as surplus or new-old-stock. Verify the encoder condition (absolute counter function, connector integrity) and bearing condition on any non-new unit before installation.

Q5: Does the MDMA202P1G include a holding brake?

No. The MDMA202P1G (P1G suffix) does not include an electromagnetic holding brake. For vertical axes or gravity-loaded mechanisms where the motor must hold position when servo-off, specify a brake-equipped variant within the MINAS A4 MDMA202 series.
