UNI Pro 90 is a machine-control platform developed by Heller for its machining centers. Because the evidence covers several machine configurations and dates, identify the exact machine and installed controller hardware before planning repairs or migration.
Confirm the UNI Pro 90 installation
Start with the machine nameplate, controller designation, and installed board identifiers. UNI Pro 90 installations were reported on Heller MCA-H150, MC16, MCP H-150, and MCP H-200 machines, but this does not establish that every machine of those types used identical hardware.
| Evidence item | Engineering interpretation |
|---|---|
| UNI Pro 90 | Heller-developed machine control |
| MCP H-150 and MCP H-200 | Reported with Motorola 68030-family CPUs and a Unix operating system |
| MCA-H150 and MC16 | Reported as operating with UNI Pro 90; internal hardware was not identified |
| Newer Heller machines | Reported as supplied with Siemens 840D controls |
Interpret the hardware evidence carefully
The Motorola 68030-family CPU and Unix operating-system details apply only to the two reported MCP installations. Do not assume that an MCA-H150, MC16, or another UNI Pro 90 machine contains the same processor, board revision, storage device, or software image. Inspect the installed modules and documentation before ordering replacements.
A report of one system crash over four years describes one site's experience, not a guaranteed reliability specification. Use machine-specific alarms, diagnostics, and maintenance records when evaluating an operating fault.
Assess support and replacement status
A January 2004 report stated that UNI Pro development had stopped approximately five years earlier. A March 2006 report likewise stated that the control was no longer being developed for cost reasons and that new Heller machines used the Siemens 840D. These historical statements support treating UNI Pro 90 as a discontinued legacy platform, but they do not prove present-day parts availability or define a direct retrofit path.
- Record the Heller machine type, serial identification, UNI Pro designation, and every controller board or module identifier.
- Preserve the available machine programs, parameters, tool data, and documentation using the machine's existing supported procedures.
- Ask Heller through its official support channels to confirm parts, documentation, and migration options for the recorded configuration.
- If replacement is required, obtain a machine-specific engineering assessment; the reported use of Siemens 840D on newer machines does not establish plug-compatible hardware or software.
Verify the engineering decision
For continued operation, verify that recoverable documentation and configuration data exist and that replacement components can be matched to the installed revisions. For modernization, verify the complete machine interface scope—including axes, spindle, I/O, pallet handling, safety functions, and application logic—against the proposed control. The supplied evidence provides no electrical drawings, software versions, interface specifications, or conversion procedure.
FAQ
Is the Heller UNI Pro 90 still manufactured?
Historical reports from 2004 and 2006 state that UNI Pro development had ended and that newer Heller machines used Siemens controls. Confirm current parts and service status with Heller for the exact machine configuration.
What CPU and operating system does UNI Pro 90 use?
Two reported installations on MCP H-150 and MCP H-200 machines used Motorola 68030-family CPUs and a Unix operating system. Inspect the installed hardware before applying that description to another UNI Pro 90 machine.
Can a UNI Pro 90 be replaced directly with a Siemens 840D?
The evidence only states that newer Heller machines were supplied with Siemens 840D controls. It does not establish a direct retrofit, so verify all machine interfaces, application logic, safety functions, and hardware compatibility through a machine-specific engineering assessment.
