Code Analysis
| Character Segment | Description | Detailed Explanation |
|---|---|---|
| MPL | Series Identifier | MPL series low-inertia brushless AC servo motor, featuring high dynamic response and high-precision positioning, suitable for medium and small power motion control applications |
| A | Voltage/Frame Derivative Code | 230V AC three-phase voltage rating; code B corresponds to 460V AC, which must be strictly matched with the drive’s power supply specification |
| 420 | Frame + Stack Length | Combined code:
– 4: Frame 4 (115mm flange size, IEC Metric FF mounting) – 20: Stack length code (corresponding to 50.8mm stack length, directly determining torque/power rating) |
| P | Performance/Configuration Code | Standard performance grade, without enhanced heat dissipation or protection; derivative codes such as S stand for high protection, and E stands for customized configuration |
| HJ | Feedback + Connector | Combined code:
– H: 2000-line incremental encoder; code K stands for absolute encoder (suitable for power-off memory positioning) – J: SpeedTEC DIN connector (180° rotatable right-angle type), compatible with single-cable solutions |
| 72 | Mechanical Configuration (Shaft + Brake) | Combined code:
– 7: Keyed shaft (no shaft seal); code 8 stands for keyless shaft – 2: No brake; code 4 stands for with 24V DC brake |
| AA | Version/Customization Attribute | Industrial-grade standard configuration, without non-standard customization (such as non-standard shaft diameter, special protection, etc.) |
FAQ:
1.Can the MPL-A420P-HJ72AA be directly connected to a 460V AC three-phase power supply?
MPL-A420P-HJ72AA cannot be directly connected to 460V AC three-phase power supply. The rated voltage is 230V AC three-phase (the model suffix “A” corresponds to this voltage level), 460V is far beyond the tolerance range of its insulation and windings, and direct connection will burn the windings.
2.What is the standard bolt torque for MPL-A420P-HJ72AA flange installation?
| Bolt Specification | Strength Grade | Standard Torque (Dry Condition) | Remarks |
|---|---|---|---|
| M12×1.75 | Class 8.8 | 45–50 N·m (33–37 lb‑ft) | Recommended value; tighten diagonally in 3 stages (50%→80%→100%) |
| M12×1.75 | Class 10.9 | 60–65 N·m (44–48 lb‑ft) | Adapted value for high-strength bolts |
3.What is the core difference between MPL-A420P-HJ72AA and the same series model MPL-A420P-HJ74AA with holding brake?
| Key Item | MPL‑A420P‑HJ72AA | MPL‑A420P‑HJ74AA |
|---|---|---|
| Holding Brake | None | Integrated 24V DC spring‑applied power‑off brake |
| Model Suffix Significance | “72AA” = no brake | “74AA” = with brake |
| Weight | ~12.56 lb | Slightly heavier (brake assembly added) |
| Wiring & Connection | No brake power/feedback lines | Requires 24V DC brake power & signal wires |
| Typical Application | Horizontal axes, non‑load‑holding scenarios | Vertical axes, load‑holding, emergency stop |
| Rotor Inertia | Standard | Slightly higher (due to brake rotor) |
