The smallest servo drive ever, now FSoE Certified.
Safety has never been this small.
The features you fell in love with…
The Denali Series is one of Novanta’s flagship servo drives, part of the Summit Collection. It’s compact design and best-in-class performance make it one of the most advanced servo drives on the market. Specifically designed for applications where space comes at a premium and maximum performance is a must, Denali has become a household name in the industry.
… and the ones that will rekindle the spark.
Built on top of the standard Denali servo drive, our Safety Certified version has reached new heights in the servo drive space. Improving Denali has been an exciting yet difficult challenge – improving such an advanced piece of technology requires a sum of research, development and coordination. Novanta has not only achieved this, but built on the existing platform advanced safety functions over EtherCAT, without compromising any specs or performance.

General
Our rotors and stators are designed together and should be used in unison. You cannot take a UTH rotor and use it with a UTS stator. More information about rotary motors.
Our motors are not vacuum rated, but have been used in vacuum environments. Baking the motors is one way to reduce particle count, resulting in reduced motor outgassing while under vaccum. For more information on our standard motor products click here.
If the drive being used has an algorithm for motor commutation, based on shaft position measured by an encoder, then hall devices are not necessary. Very high friction systems and very low friction systems sometimes cause the algorithms to incorrectly commutate the motor. Drives without motor phasing or “commutation” algorithms will need Hall sensors to function properly.

General Technology
It is likely that contamination over a period of time has prevented the shaft from floating freely. We strongly recommend the unit be returned to your local Westwind product service centre for investigation.
Zettlex inductive encoders are generally not susceptible to emissions from other sources due to a number of factors: – the Receive circuits are arranged as balanced quadrupoles (thus negating the effect of incoming plane waves), the signal from the Target is at a highly specific frequency and the sensor uses synchronous detection. Zettlex sensors are suitable for medical and SATCOM applications where permissible emission susceptibility is particularly stringent. The IncOder product range is particularly robust in harsh EMC conditions because it is housed in a metal casing that acts as a Faraday cage.
Yes, there are downsides to a talbot imaging based optical encoder. The talbot image is created by using a reflective diffraction grating, therefore the scale must be kept clean and generally free of debris. In certain applications like CNC, contaminants from the surrounding environment, like oil and grease, could affect the signal of your encoder. Talbot imaging based encoders should be used in relatively clean environments, or should be protected from contaminants. Click for more information on talbot imaging based optical encoders.
IncOder Specific
Contact Celera Motion or your local representative.
No. Magnets produce DC fields. IncOder’s operation is based on the detection of AC electro-magnetic fields at a highly specific frequency.
Yes. Clear, hard-anodized is standard and clear Alocrom or Surtec650 are available as extended Product Options. Custom finishes include olive drab, black anodized, red anodized and powder coated. Other finishes are also possible – contact Celera Motion or your local representative.
Light Industrial Precision Machining
Yes, the M321/M328 spindle is specifically designed to have replaceable collets without the need to rebalance the shaft. Click for more information on the Light Industrial Series spindles.
Both the M321 and the M328 need to be watercooled and connected to an external chiller, due to the high speed of operation and the powerful integrated motor. The D1091 is an air cooled spindle, and does not require water cooling. Click for more information on the Light Industrial Series spindles.
Various collet sizes are available for the M321/M328, from 3mm, 1/8″, 4mm to a maximum of 6mm shank diameter, both for the manual and automatic collet versions. Additional specifications.
PCB Drilling and Routing
Most of our modern PCB Drilling & Routing spindles are fitted with a bonded collet, which cannot be removed by the customer. In this case, the spindle should be sent to Celera Motion’s Westwind authorized repair center to have a new collet fitted. However, some products are still fitted with a removable collet, and in this case, the customer should contact the closest Air Bearing Spindles Center of Excellence found in the Contact section of our website, to discuss which part to order.
Air pressure used for a PCB Drilling & Routing Series spindle should be 5 to 6 bar (72.5 to 87 psi). More information on the PCB Drilling & Routing Series.
Please refer to your machine manufacturer’s recommendations. Currently 6.35mm is the maximum we recommend for most Westwind PCB Spindles.
Product Specific
Celera Motion’s Ingenia products are servo drives. However, the Base Series of servo drives allow for local programming capability which can enable them to operate as controllers. This standalone performance is not suitable for fast update rate applications. Find out how the servo drives can be used.
Yes, Aura Series absolute optical encoders offer the following communication protocols:
- BiSS (Single and Daisy-Chained)
- SSI
- SPI
- ABZ Incremental
The Everest Series servo drives are CiA-301, CiA-303, CiA-305, CiA-306 and CiA-402 (4.0) compliant.
Rotary Atomizer Spindles
Yes, lightweight materials are used in rotary atomizer spindles. Many of our atomizers are designed to be fitted to robotic arms or linear movers, therefore the atomizer weight is extremely important. Click here for additional information on coating atomizer spindles.
All of Celera Motion’s Westwind atomizers are designed to operate without the need for water cooling. These coating atomizers rely on turbine exhaust air and paint flow through the shaft to remove any heat generated within the bearing assembly. Click for more information on our coating atomizer spindles.
Most of our atomizers are designed to be fitted with some form of external speed sensor to monitor shaft speed. These sensors can be activated optically, by black/white stripes on the turbine wheel, or magnetically, by magnets embedded in the side of the turbine wheel. It is the responsibility of the OEM to supply and fit the appropriate sensors and circuitry. Click here for additional information on our coating atomizer spindles.
