To convert between Kt_sine and Kt_trap, use the equation below. Kt_sine = 0.87 * Kt_trap Click here for more motor unit conversions.

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.

Our servo drives are FOC based on SVPWM (Space Vector Pulse Width Modulation). To learn more about servo drives, check out our Servo drives and motor control knowledge base.

Yes, most spindles are fitted with a speed sensor to facilitate shaft speed measurement.

No, you should not power on the servo drive below the minimum supply voltage.

Generally, a metal exclusion zone is required in the gap between the sensor Target and Antenna. In principle, a metal shield may be inserted between these components however the skin depth through which the excitation signals can permeate limits the thickness of the metal shield. The lower the excitation frequency, the greater the thickness of permissible metal. The maximum thickness of metal depends on the actual metal. If a metal shield is to be used then non-magnetic stainless steel is most preferred with aluminum, steel, copper, or brass least preferred. Practically, metal thicknesses of <1.6mm would be necessary. Please note that resolution and accuracy would be limited in such an arrangement.

Yes. It may be possible to integrate machinery control software into the microprocessor containing the Zettlex sensor software. Power supply, frequency generation, etc. can also be shared between host and sensor system.

Yes. As a custom solution, Zettlex sensor software can be parameterized to control multiple sensors of differing geometries.

No. Magnets produce DC fields. IncOder’s operation is based on the detection of AC electro-magnetic fields at a highly specific frequency.

Yes. A RoHS Compliance Certificate is available on request. Zettlex IncOders contain no hazardous, restricted or substances of very high concern in concentrations of >0.1% by mass and a REACH statement is available on request.

No, but some customers are using IncOders in space equipment following their own qualification of equipment incorporating IncOders.

Yes. Many IncOders are used near powerful sources of electromagnetic noise such as motors or transformers. IncOder’s aluminium housing produces a Faraday cage effect around the internal electronics and the technology is designed so that incoming, far-field radiation is self cancelling or filtered out.

Yes – the Zero Point can be changed using the Zero Set and Zero Reset lines on the electrical interface. The Zero Set signal will set the current IncOder position as the Zero Point (held in memory when power is removed). Zero-Reset signal will reset the Zero Point to the factory setting (held in memory when power is removed). To use, the relevant connection should be connected to an electrical ground (<0.5 V) for at least 3 seconds at power-up but left unconnected (i.e. open circuit) during operation.

The longer the transmission distance (Cable Length), the slower the recommended Baud Rate. This table shows recommended Baud Rates vs. Cable Length.

Yes. IncOders are often used as an alternative to resolvers – especially pancake or slab resolvers – which are becoming increasingly expensive and difficult to source. Unlike a resolver, IncOders accept a DC power supply and produce digital data. In effect, the IncOder replaces a resolver and its energization and digital conversion circuitry.

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.

For normal machining applications, the minimum recommended speed for the M321 and M328 Light Industrial Series spindles are 10,000 rpm, although for soft materials such as perspex, lower speeds may be possible. More information on the Light Industrial Series spindles.

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.

Supply pressure for the cooling water of a PCB Drilling & Routing Series spindle should be 3 to 4 bar (43.5 – 58 psi). Specifications for the PCB Drilling & Routing Series can be found here.

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

Inegnia servo drives are compatible with all of these communication protocols, dependent on the drive model. To select a servo drive for your Aura Series absolute optical encoder, use our Ingenia Product Finder .

The Everest Series servo drives are CiA-301, CiA-303, CiA-305, CiA-306 and CiA-402 (4.0) compliant.

Yes, a detailed application guide is available to help the customer develop their own interface board to mount the Everest NET servo drives.

Yes, you can cut Aura P glass scales to shorter lengths. However, when doing so, you have to take some precautions. On both ends of the scale is a buffer zone. These zones limit the Aura P from optically traveling off of the grating patterns. If the buffer zones are altered by shortening the scale, Aura P may report an incorrect position at either end of the scale. Therefore, before making any cuts, ensure that there is an adequate measuring distance that includes buffer zones on both ends of the axis of motion. The mechanical alignment can be referenced in the Installation section of the datasheet. The encoder optics should always be at least 2.4576 mm from the scale edge. This value accounts for 0.02 mm of potential glass edge chips and defects resulting from the cutting process.

Pluggable terminal block power connectors are not available for the Everest XCR. The Everest NET supports pluggable terminal block power connectors if you develop a specific interface board on top of the drive. To learn how to develop this interface board, read the EVE-NET application guide, or contact us for support.

Yes, scope data is available. The sampling rates are dependent on the firmware/software platform. Sampling rates up to 25 kHz are available. We have both real-time polling/monitoring sampling methods. More information about Everest Series.

Yes, the analog input can be used as a command source as part of a customization process with the Capitan Series servo drives. Click to inquire about customization.

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.
