More Information

Overview Manuals Configuration Key Fit Planning Evidence Package Product Applications

Features:

  • Brake-equipped configuration: Yaskawa lists a 24 VDC holding brake for this exact model.
  • Keyed mechanical output: The shaft end is straight with key and tap.
  • Incremental feedback: A 24-bit incremental encoder identifies the control-feedback variant.
This model combines the 400 W SGM7J frame with the specific A6C shaft-and-brake option set.

Its official record also identifies a 200 V supply class, 3000 1/min rated speed and 6000 1/min maximum speed.

Selection should preserve the complete model because power rating alone does not identify encoder type, shaft form or brake content.

Apter Power can review an SGM7J-04AFA6C enquiry against the official incremental-feedback, keyed-shaft and 24 VDC holding-brake configuration.

Important Notice: No qualified exact-model English PDF is attached. Use the complete product model in every document request.
  • Feedback identifier: Confirm the official 24-bit incremental encoder entry.
  • Shaft identifier: Confirm straight shaft with key and tap rather than a plain shaft.
  • Option identifier: Confirm the listed 24 VDC holding-brake option.
  • Model control: Keep the final 6C characters in quotations, receiving checks and maintenance records.
  • Published envelope: Use 74.7 mm height, 60 mm width and 156 mm depth as the official outline reference.
  • Coupling plan: Base hub selection on the keyed shaft shown in the exact-model record and CAD resource.
  • Flange statement: Treat Sigma-5 flange compatibility as one fit input, not as proof of a complete configuration match.
  • Brake allowance: Include the brake-equipped body and associated connection requirements in the installation review.
  • Exact product record: Retain the Yaskawa page that names SGM7J-04AFA6C and its option set.
  • CAD reference: Use the official SGM7J-04A_A6C data package for mechanical review.
  • Catalog context: Use the current Sigma-7 200 V catalog for series-level planning only.
  • Receiving evidence: Photograph the complete nameplate code before accepting the motor into the spare pool.
  • Brake-equipped servo axes: Consider this variant where the documented SGM7J configuration calls for a holding brake.
  • Keyed coupling designs: Use it where the machine drawing specifies a straight shaft with key and tap.
  • Incremental-control architectures: Match it to systems documented for 24-bit incremental feedback.
  • Compact Sigma-7 layouts: Apply the official outline and Sigma-5 flange statement during fit assessment.
Description
Where a 400 W Sigma-7 axis requires a straight shaft with key and tap, SGM7J-04AFA6C provides that mechanical interface together with Yaskawa's medium-inertia, high-speed motor design.

The 24-bit incremental encoder and 24 VDC holding-brake option define SGM7J-04AFA6C as a brake-equipped incremental configuration, keeping its feedback and stationary-holding functions explicit in the machine record.

Yaskawa lists high efficiency, low heat generation, up to 20% downsizing and Sigma-5 flange compatibility for SGM7J-04AFA6C; these features support compact fit planning while the complete suffix remains the configuration authority.

Technical notes
The holding brake on SGM7J-04AFA6C has a separate 24 VDC function and must not be confused with the motor power connection. A release fault can leave the shaft restrained even when the SERVOPACK is ready. Diagnose the brake circuit and command timing before replacing motion-control hardware or forcing the coupled load.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which Yaskawa file should be used to check coupling clearance for SGM7J-04AFA6C?
Use the official SGM7J-04A_A6C CAD package and verify the full brake-equipped outline; the flange statement alone does not define coupling or rear clearance.
A received motor shows 400 W but the final 6C is missing from SGM7J-04AFA6C paperwork. Can it be booked into stock?
Place it on hold until the complete nameplate code is verified because the 6C ending identifies the keyed-shaft and brake configuration.
What feedback detail must the control record retain for SGM7J-04AFA6C?
Record the official 24-bit incremental encoder type so commissioning documents do not treat this variant as an absolute-feedback motor.
Does Sigma-5 flange compatibility make SGM7J-04AFA6C a complete drop-in match?
No. Use the flange statement only as one mechanical input and separately confirm shaft form, encoder type, brake option and overall depth.
How should the low-heat feature of SGM7J-04AFA6C be used in an enclosure review?
Treat Yaskawa's high-efficiency, low-heat statement as a planning benefit, then check the actual cabinet and machine thermal conditions for the installed duty.
Which exact option should a buyer call out for SGM7J-04AFA6C?
Call out the 24 VDC holding brake together with the keyed shaft and 24-bit incremental feedback so the quotation is tied to the full configuration.
