Specifications:
The servo motors EMMT-AS are designed with an IP67 protection rating, suitable for ambient temperatures ranging from -15°C to +40°C, and up to 80°C with a derating of 1.5% per degree Celsius. The storage temperature ranges from -20°C to +70°C, with a maximum winding temperature of 155°C. The motors feature digital motor temperature transmission via EnDat 2.2 and conform to EN 60034-1 standards with a thermal class F. They operate in relative humidity levels of 0-90% (non-condensing) and are suitable for altitudes up to 4000 meters with derating above 1000 meters.

Certifications and Compliance:
The motors comply with various EU directives including Low Voltage, EMC, RoHS, and Machinery Directives, and have UKCA marking for UK regulations. They are RCM certified, with UL certification pending. They meet vibration and shock resistance standards as per EN 60068-2-6 and EN 60068-2-27.

Encoder Specifications:
The encoders are available in absolute single-turn and multi-turn configurations, with an operating voltage of 5V DC and a range of 3.6 to 14V DC. They use the EnDat 2.2 protocol with a maximum cycle rate of 16 MHz. The measuring principle is inductive, with position values per revolution varying by flange size.

Torque and Speed Characteristics:
The datasheet provides detailed torque as a function of rotational speed for various flange sizes (60, 80, 100, 150, 190) and winding configurations (LS, HS, HV, HT). It includes peak and nominal torque values and emphasizes observing maximum permissible rotational speeds for add-on components.

Dimensions:
Detailed dimensions are provided for flange sizes 60, 80, 100, 150, and 190, including interface codes, motor lengths, and featherkey specifications. CAD data is available for download.

Ordering Information:
The document lists part numbers and configurations for different flange sizes, lengths, winding types, and encoder options, including those with and without brakes and featherkeys.

Overview: This document provides detailed ordering information for Festo's EMMT-AS servo motors, including specifications for different configurations, accessories, and technical data for motor cables.

1. Ordering Data:

Rotary Shaft Seal: Lists part numbers and types for motors with rotary shaft seals, categorized by flange size (150 and 190) and motor specifications such as winding type, encoder type, and brake options.
Featherkey and Rotary Shaft Seal: Similar to the above, but includes featherkey options, with part numbers and types for different configurations.
Modular Product System: Provides a table for ordering modular components, detailing motor sizes (60, 80, 100), series, motor technology, flange size, length, output shaft type, and electrical connections.

2. Accessories:

Gear Units: Lists gear units compatible with different motor sizes (60, 80, 100, 150), including gear ratios and part numbers.
Right-Angle Gear Units: Provides similar information for right-angle gear units.
Rotary Shaft Seal: Details the rotary shaft seal options for different flange sizes, including part numbers and installation notes.

3. Technical Data:

Motor Cables: Describes cable specifications, including cross-section sizes, cable composition, shielding, bending radius, pollution degree, ambient temperature range, and compliance with protection and material standards.
Ordering Data for Motor Cables: Lists part numbers and types for motor cables of various lengths and cross-sections, with specific notes on cable length increments and compatibility with motor controllers.

Key Notes:

Using a rotary shaft seal requires a 10% reduction in nominal torque.
For cable lengths over 25 meters, technical clarification is recommended.
Motors with holding brakes require a logic power supply of more than 24 V DC.
