Safety Safety Intended use The encoder described here has been designed as a sensor system that delivers angle infor- mation used for actuating and positioning the following motors: Brushless DC-servomotors The encoder is suitable in particular for tasks in the following fields of application: Robotics ...
Therefore the Machinery Directive does not apply to our products. The products described here are not “incomplete machines”. Therefore installation instructions are not normally issued by FAULHABER. Low Voltage Directive (2014/35/EU) The Low Voltage Directive applies for all electrical equipment with a nominal voltage of 75 to 1500 V DC and 50 to 1000 V AC.
Product description Product description General product description The AEMT-12/16 L series encoder is a magnetic multiturn absolute encoder. The encoder provides the absolute angle information within one revolution (singleturn position) and the current revolution count (multiturn count). The absolute position, relative to the entire drive system, can be determined from the multiturn count and the singleturn position.
20 bit 24 bit 32 bit In combination with a FAULHABER Motion Controller of Generation V3.0, an overall resolution (multiturn + singleturn) of maximum 32 bit is possible. With an singleturn resolution of 12 bits, a maximum multiturn resolution of 20 bits is possible.
Product description Interpretation of position values and handling of position over- In the standard configuration of the AEMT-12/16 L, there is a number range from 0 to ∙ 2 268 435 455 positions (2 – 1). Then the count starts again from the beginning. Multiturn resolution Position...
Product description The value to which the count of the encoder is reset via the preset pin is not unambig- uously 0, but instead lies within a range of ±8192 increments, depending on the singleturn position. The preset value is set at the factory to a signed interpretation of the position data, see chap.
Installation Installation Only trained experts and instructed persons with knowledge of the following fields may install and commission the encoder: Automation technology Standards and regulations (such as the EMC Directive) Low Voltage Directive Machinery Directive VDE regulations (DIN VDE 0100) Accident prevention regulations ...
Installation 4.1.2 Mounting the motor Fig. 5: Mounting example – 22xxBX4 AEMTL series NOTICE! Excessive radial loads on the servomotor or excessively tightened fastening screws can cause irreparable damage to the mounting flange. Do not apply a radial force exceeding 30 N at the rear end of the motor. Make sure that the screws are tightened to max.
Installation Electrical connection 4.2.1 Notes on the electrical connection NOTICE! Installation and connection of the encoder when the power supply is applied can damage the encoder. Prior to all aspects of installation and connection work on the encoder, switch off the power supply.
Installation 4.2.3 Electrical data Tab. 3: Encoder supply Power supply U 4.5…5.5 V Typical: 25 mA Rated current consumption Maximum: 35 mA Typical: 90 mA Standby current under load Set-up time after power on 20 ms = 5 V on non-loaded outputs = 120 Ω...
When connecting the line driver interface on the controller side: Use transceiver module. The transceiver is already integrated in FAULHABER Motion Controllers of genera- tion V3.0. Recommended transceiver components: iC-HF, SN65LBC179, SN75179B, DS90LV019 Use a terminating resistor between data and data starting at a cable length of 1 m.

Installation Data Data Data Data Data Data Fig. 7: Termination types Standard AC termination Split termination = 100…130 Ω Standard: Terminating resistor R = 60 Ω). Split termination: The terminating resistor is split symmetrically (e. g. R The capacitor C (4.7...10 nF) discharges common-mode currents to ground. This leads to an increased interference resistance of the signal transmission.
Installation 4.2.4.2 Preset input During commissioning and after a battery change, a voltage pulse must be applied to the preset input (pin 1) to reset the revolution count. Encoder internal Switch Dig-In 1...4.7 kW Fig. 8: Preset electrical circuit diagram ...

Installation 4.3.2 Shielding Shield cables in all cases. Shield cables that are longer than 3 m with tightly meshed copper braiding. Shield all supply lines according to current guidelines/standards (e.g., IPC-A-620B) and connect using (round) shield clamp. In special cases (e.g., with pigtail) or after qualification, the shield can be omitted for the following cables: Cables with length <50 cm ...
Installation 4.3.3 Establishing the shield connection The best results when establishing a shield connection on the cable are achieved in the fol- lowing way: Fig. 14: Motor cable shield connection Outer cable shield Heat-shrink tubing Braided shield Crimp-sleeve Shield clamp 1.
Installation 4.3.4 Establishing shield connection with cable lug A shield connection with cable lug should be avoided whenever possible. If it is necessary, however, the connection should be established as follows. Fig. 15: Shield connection with cable lug Screw Lock washer Wall Spring washer Wire eyelet...
Installation Commissioning and battery change The drive system is properly mounted and wired. NOTICE! Damage to mechanics The multiturn function is only guaranteed if the data of the AEMT-12/16 L are used directly for position determination. Do not set the position at the reference position on the software side in the controller to 0.
Installation The nERROR error bit can only be reset together with the revolution count of the encoder. After the battery voltage drops to U < 2.8 V and following battery change, repeat steps 2 to 4. When selecting an appropriate battery with a battery voltage of 3.6 V and a capacity of 1 Ah, a typical service life of 10 years is possible with the standard configuration.
