Reliance Electric 6MDBN-8P0101 | MD60 2HP 230V AC Drive In Stock

Architect’s Product Breakdown

The 6MDBN-8P0101 is a compact 200–240V AC variable frequency drive belonging to the Reliance Electric MD60 family. Designed as a cost-effective micro-drive for standalone machine tools, small conveyors, fans, pumps, and packaging equipment, it controls standard 3-phase induction motors up to 2.0 HP (1.5 kW).

The model number configuration breaks down as:

• 6MD: MD60 Drive Series
• B: Voltage Class (200–240V AC, 3-Phase Input)
• N: Filter Type (No Integrated EMC/RFI Filter)
• 8P0: Current Rating (8.0 Amps Output)
• 101: Enclosure / Frame Size (IP20 / NEMA Open Type, Frame A)

Because the MD60 platform shares underlying hardware architecture with Allen-Bradley PowerFlex 4 series drives (due to historical Rockwell Automation branding crossovers), the unit offers quick parameter setup, digital I/O control, and flexible keypad navigation in an space-saving DIN-rail/panel mount footprint.

Key Technical Specifications

Field Engineer’s Pitfall Guide (Unique Value)

• RUNNING 1-PHASE INPUT ON A 3-PHASE DRIVE: Do not wire single-phase power directly into a 3-phase input drive without derating. The 6MDBN-8P0101 expects 3-phase power. While it may power up on single-phase supply across L1/L2, doing so without at least 50% load current derating will cause excessive DC bus ripple voltage, thermal stress on input diodes, and premature capacitor failure.
• MOUNTING IN HIGH-EMI/CE ENVIRONMENT WITHOUT EXTERNAL FILTER: Because this unit lacks an internal EMC filter (“N” code), extra line filtration is required in sensitive environments. If installed near sensitive PLC analog inputs, sensors, or radio equipment, high-frequency switching noise on motor leads can bleed into nearby instrumentation. Install an external EMC line filter on the AC input side.
• USING UN-SHIELDED MOTOR LEADS FOR LONG RUNS: Keep motor cable lengths under 50 meters (160 ft) unless an output reactor is installed. Long cable runs generate high dv/dt voltage spikes at motor terminals due to transmission line reflections, which can break down motor winding insulation and trip the drive on instant Overcurrent (F12 / F004) faults.

QA & Testing SOP (Transparency)

1. Visual & Mechanical Inspection: Inspection of heatsink fins, housing latches, keypad buttons, and terminal block screws for thermal discoloration or mechanical wear.
2. DC Bus & Capacitor Bus Health Test: Equivalent Series Resistance (ESR) and capacitance checks on main DC bus electrolytic filter capacitors to ensure low ripple voltage under load.
3. Power Component Static Test: Diode bridge and IGBT power module forward/reverse diode drops measured using a multimeter to detect shorted or degraded phases.
4. Full-Load Dynamic Dynamometer Test: Drive configured and run at full rated 8.0 A load for 2 hours while monitoring thermal output, current balance across all 3 output phases, and speed stability.
5. Factory Default Reset & Protective Packaging: Reset to default motor parameters (60Hz, 230V base), packed with anti-static static-shielding wrap, and fitted with custom foam inserts in a heavy-duty shipping box.

Technical FAQ

Can I replace the Reliance 6MDBN-8P0101 with an Allen-Bradley PowerFlex 4 drive?

Yes. The Reliance Electric MD60 series (including 6MDBN-8P0101) shares its core design and footprint with the Allen-Bradley PowerFlex 4 series (e.g., catalog number 22A-B8P0N104). Parameter structures, terminal layouts, and physical dimensions are functionally identical.

What causes an “Overcurrent” or “F004” fault on start-up?

This fault indicates motor current has exceeded the drive’s instantaneous current limit. Check for:

1. Ground faults or short circuits in motor wiring.
2. Acceleration time (A067) set too aggressively for the load inertia.
3. Incorrect motor nameplate FLA parameters programmed into the drive.

Does the 6MDBN-8P0101 include an internal dynamic braking resistor?

No. Frame A drives do not have an internal dynamic braking resistor. For applications requiring rapid deceleration of high-inertia loads, an optional external braking chopper / resistor unit must be added, or the deceleration time must be extended to prevent DC Bus Overvoltage trips.

What is the maximum carrier frequency supported by this drive?

The drive supports carrier frequencies up to 16 kHz. However, operating at higher carrier frequencies (above 4 kHz) reduces audible motor noise but requires derating the drive’s continuous output current to prevent thermal shutdown of the IGBTs.
