Overview Manuals Selection Installation Service Checks Applications

Features:

  • Command architecture: Accepts analog-voltage and pulse-train references for a controller-driven Sigma-7 axis.
  • Axis class: Matches the 100 V, 400 W application represented by the complete drive code.
  • Service identity: Keeps the 00A suffix tied to the installed connectors, feedback and option arrangement.
SGD7S-2R8F00A is suited to machinery in which the motion controller sends an analog or pulse-train command rather than a network reference.

During service, the command interface, servomotor, encoder and parameter set must remain aligned as one axis; a similar Sigma-7 frame does not prove control compatibility.

Using the complete SGD7S-2R8F00A identity helps purchasing and commissioning teams avoid a drive that fits mechanically but cannot reproduce the installed command path.

Apter Power supports exact-model document review, quotation, and procurement for the YASKAWA SGD7S-2R8F00A Sigma-7 Analog/Pulse SERVOPACK.

  • Voltage and capacity: confirm 100 V class and 400 W motor capacity.
  • Interface: retain the analog-voltage/pulse-train command architecture.
  • Suffix: verify 00A and all installed hardware-option evidence.
  • Isolation: lock out main and control power and prove DC-bus discharge.
  • Connections: transfer power, motor, encoder, I/O, and grounding by terminal identity.
  • Parameters: back up and reconcile the approved servo settings before trial operation.
  • Before substitution: inspect wiring, motor insulation, encoder feedback, and mechanical load.
  • Trial operation: use the approved low-risk startup sequence and verify rotation and feedback.
  • Record: retain the old and new nameplates, parameter backup, alarms, and final test results.
  • Position control: pulse-train commanded Sigma-7 axes.
  • Speed or torque control: analog-reference applications configured for the exact drive.
  • Maintenance: like-for-like replacement of a verified SGD7S-2R8F00A.
Description
In a Sigma-7 motion axis, SGD7S-2R8F00A converts an analog-voltage or pulse-train command into controlled motor operation for the matched servomotor and encoder. This makes the command interface—not only the power rating—a key part of the drive identity.

When an axis powers up but does not follow the controller, SGD7S-2R8F00A should be checked as a complete signal chain: reference type and polarity, enable logic, encoder feedback, motor wiring and restored parameters. Separating those boundaries prevents an interface fault from being mistaken for failed power hardware.

For replacement work, SGD7S-2R8F00A should remain tied to the 100 V, 400 W application and the full 00A suffix. Retaining the exact code with the parameter backup and connector record reduces commissioning risk after installation.

Technical notes
For SGD7S-2R8F00A, isolate the main and control supplies, verify DC-bus discharge, record every connector, and match the complete model before replacement. Confirm the 100 V power class, 400 W motor pairing, analog/pulse command wiring, encoder interface, parameters, and grounding; stop commissioning if any suffix, feedback, or option differs.

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.
The machine record says only SGD7S-2R8F. What evidence is needed before ordering SGD7S-2R8F00A?
Recover the complete 00A suffix from the drive label, approved parts list, wiring drawings or parameter backup; the shortened frame code does not identify the command interface or option build.
SGD7S-2R8F00A powers up, but the axis ignores the controller command. What should be checked first?
Confirm whether the controller is supplying the expected analog-voltage or pulse-train reference, then check polarity, enable logic, I/O mapping and the restored control parameters before replacing hardware.
Can an EtherCAT version of the 2R8F drive replace SGD7S-2R8F00A without control changes?
No. The network and analog/pulse versions use different command architectures; a substitution requires an approved control, wiring and parameter redesign.
After SGD7S-2R8F00A is fitted, the axis alarms as soon as it is enabled. Where should diagnosis start?
Check motor and encoder identity, connector seating, phase wiring, load restraint, parameter transfer and the active alarm before attempting another start.
What must be done before disconnecting power or motor wiring from SGD7S-2R8F00A?
Lock out main and control supplies, wait the documented discharge interval and verify the DC bus is safe with an approved instrument before touching terminals.
What proves that SGD7S-2R8F00A has been commissioned successfully?
Record the exact model, restored parameter set, correct direction, stable feedback, limit and stop behavior, alarm-free trial operation and the final machine cycle.
