Infranor PACHP Brushless Servo Drives Review: Specs, Price and Applications
Updated: 4 days ago

PACHP is Infranor’s panel-mounted servo-drive platform for rotary and linear motors. The family includes different power/input arrangements, feedback and control variants. Standard STO and the separate PACHP Safety advanced-function product must be distinguished rather than assigning all functions to every drive.
Quick Verdict
Assess PACHP when the selected power stage, feedback and control interface fit the actual axis. Resolve the complete part/firmware configuration first. The largest current model and a smaller AC-input variant do not share one universal supply arrangement.
Infranor PACHP Brushless Servo Drives at a Glance
Specification | Details |
Motor scope | Applicable rotary and linear servo motors |
Source continuous range | 2.5–75 Arms across models |
230/11 example | 110–230 VAC single-phase input; 5.5 Arms continuous / 11 Arms peak |
Higher-current variants | Source identifies separate external DC power/GDPS arrangements on selected models |
Control choices | Analog, I/O, sequencer, RS-232 or applicable fieldbus variants |
Feedback | Applicable resolver, incremental/Hall and digital absolute interfaces |
Safety distinction | Standard STO; advanced Safety functions require the appropriate separate configuration |
Price | Request a quote for actual power, input, feedback, protocol and firmware scope |
Design and Engineering Assessment
Input AC voltage, internal DC bus and external-DC configurations are different electrical descriptions. Do not interpret a family DC-bus range as a universal mains input rating.
Peak current and continuous current differ, and their ratio is not constant across all table entries. Apply the selected drive’s permitted duration, switching frequency and installed cooling conditions.
Auto-phasing and tuning assist setup, while motor parameters, feedback alignment and the loaded mechanical system still need verification. A supported connector protocol does not remove signal/pinout or firmware compatibility work.
Resolve the Configuration
Select the actual control method and motor feedback with the power unit. Sensorless operation described with a special firmware arrangement is not a default property of every servo configuration.
For higher-power units, specify the required power supply, regeneration and protection architecture. Confirm cabling and current measurement conventions with the actual motor.
Commission and Accept
Check direction, commutation/feedback and current limits before loaded moves. Tune the mechanism, then test warm repeated duty and the required fault response.
Integrate STO into the intended machine stop strategy. Torque removal alone does not ensure controlled deceleration or gravity-load holding. Save the actual firmware and validated settings.
Applications and Selection
Configured panel-mounted rotary or linear servo axes with a defined power and control architecture.
For Infranor PACHP Brushless Servo Drives, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Price: Request a quote for the exact configuration. Compare the product, compatible control equipment, required mechanical parts, cabling and commissioning as one installed system. A component price alone does not represent the cost of a working automation axis.
Evaluate an alternative against the same duty and acceptance criteria. Match the continuous operating requirement first, then compare transient capability, feedback, mechanical fit and support. This avoids choosing between superficially similar products whose ratings describe different operating conditions.
Pros and Cons
Advantages
Broad rotary/linear servo platform
Several feedback and control choices
Configuration and tuning tools
Limitations
Input architectures vary by model
Peak-current duty is not universal
Advanced safety requires the correct product configuration
Who Should Consider Infranor PACHP Brushless Servo Drives?
Consider Infranor PACHP Brushless Servo Drives for configured panel-mounted rotary or linear servo axes with a defined power and control architecture. Establish the required operating point and installation interfaces before choosing the configuration, and use a representative loaded cycle as the acceptance basis.
Infranor PACHP Brushless Servo Drives FAQ
Can every PACHP take the same mains input?
No. Confirm the exact AC or external-DC power arrangement.
Is peak current always twice continuous current?
No. Use the actual selected model’s ratings and allowed duty.
Does the standard drive include every PACHP Safety function?
No. Advanced safety requires the correct separate Safety configuration.
Is sensorless operation automatically enabled?
No. The applicable motor, firmware and operating method must be specified.
Does auto-tuning complete machine commissioning?
No. The actual loaded mechanism still requires validation.
Does STO provide gravity holding?
No. Define the required mechanical holding and stop arrangement separately.
What should a quote include?
Power/input architecture, motor, feedback, network/control and firmware scope.
What should acceptance cover?
Loaded warm duty, limits, feedback, fault handling and restoration of validated settings.
Prices are indicative and may change. Confirm the final configuration, commercial terms and delivery schedule before ordering.
