Compatible Replacement & Equivalent Models
The following models are functionally equivalent or direct replacements for the MPL-B320P-MK24AA. Always verify electrical and mechanical compatibility before substitution.
- MPL-B320P-MK22AA — Same motor, standard DIN connector (non-rotating); drop-in mechanical replacement
- MPL-B320P-SK24AA — Keyed shaft variant; compatible if drive/coupling allows keyway
- MPL-B320P-HK24AA — With holding brake; use when axis requires power-off braking
- MPL-B320E-MK24AA — Extended temperature range (-20°C to 55°C); suitable for harsh environments
- VPL-B0631F-PJ12AA — Kinetix VP series equivalent; same frame, higher IP rating (IP67)
- TLY-A120T-HK64AA (Kollmorgen) — Cross-brand equivalent for legacy system retrofits
Note: Cross-brand replacements require drive parameter re-tuning. Contact Konmask for compatibility verification.
Why Choose the Original Model
- Plug-and-play with Kinetix drives: Native auto-configuration via ECAT/EtherNet/IP — no manual motor file loading required

- Genuine warranty: Original Allen-Bradley parts carry Rockwell Automation’s standard warranty and global service network support
- Traceability: Factory-serialized with full lot traceability — critical for regulated industries (pharma, food & beverage)
Typical Applications
- Packaging machinery (pick-and-place, form-fill-seal)
- Semiconductor wafer handling and precision positioning
- CNC machine tool axes (small-frame, high-speed spindle assist)
- Robotics joint drives and SCARA arm axes
- Printing and converting equipment
- Medical device assembly automation
System Compatibility
The MPL-B320P-MK24AA is compatible with the following Kinetix servo drive families:
- Kinetix 5700 (2198-Dxxx) — Recommended for new designs; EtherNet/IP motion
- Kinetix 5500 (2198-Hxxx) — Single-axis EtherNet/IP drive
- Kinetix 5100 (2198-Exxx) — Entry-level EtherNet/IP servo drive
- Kinetix 6500 (2094-BCxx) — Legacy integrated motion on EtherNet/IP
- Kinetix 6200 / 6000 — SERCOS III / analog interface (requires motor file)
Cable compatibility: Use 2090-XXNPMF-xxSxx series SpeedTec power cables and 2090-XXNFMF-xxSxx feedback cables for the K24 connector style.
Selection Guide
Use the MPL model number decoder to select the correct variant:
- MPL — Bulletin: Low-inertia permanent magnet servo motor
- B — Frame size: B = 63 mm
- 320 — Continuous stall torque code
- P — Shaft: P = Smooth (plain), S = Keyed
- M — Brake: M = No brake, H = Holding brake
- K24 — Connector: K24 = SpeedTec DIN rotating, K22 = SpeedTec DIN standard
- AA — Feedback: AA = Multi-turn absolute encoder (standard)
Torque-speed selection tip: For applications requiring >3000 RPM continuous, verify the motor’s torque-speed curve against your load profile. The MPL-B320P series maintains rated torque to 5000 RPM with appropriate drive bus voltage.

Replacement & Compatibility FAQ
Q: Can I replace MPL-B320P-MK24AA with MPL-B320P-MK22AA?
A: Yes. The only difference is the connector rotation style (SpeedTec rotating vs. standard). Electrically and mechanically identical. Verify cable connector compatibility.
Q: Is this motor compatible with Kinetix 5700?
A: Yes. The Kinetix 5700 drive auto-recognizes MPL series motors via the feedback cable. No manual motor file configuration required.
Q: Can I use a third-party servo motor as a replacement?
A: Functionally possible with parameter re-tuning, but not recommended for safety-critical or regulated applications. Contact us for cross-brand equivalency analysis.
Q: What is the difference between MPL and VPL series?
A: VPL (Kinetix VP) motors offer higher IP rating (IP67) and stainless-steel shaft options for washdown environments. MPL is the standard industrial series. Both are Kinetix-compatible.
Q: Do you provide a warranty on surplus units?
A: Yes. All units sold by Konmask carry a 90-day functional warranty. Extended warranty available upon request.
