5 Lexium BMI servo motors - dynamics and power (continued) Specific features Lexium BMI servo motors have been developed to comply with the following main specifications: b The ambient operating temperature is - 0...+ 50C/ + 32...+ 122F . b The maximum operating altitude is 1000 m/ 3281 ft without derating; 2000 m/ 6562 ft with a maximum ambient temperature of 45C/ 113F and a continuous power reduction of 1% for every 100 m/ 328 ft above 1000 m/ 3281 ft ; and 3000 m/ 9842 ft with a maximum ambient temperature of 40C/ 104F and a continuous power reduction of 1% for every 100 m/ 328 ft above 1000 m/ 3281 ft . b The servo motor can withstand 5...95% relative humidity (non-condensing). b The windings are insulation class F in accordance with standard IEC 60034-1 (maximum temperature for windings is 155C/ 311F ). b Thermal protection is provided and controlled by the Lexium 32i integrated drive via the motor temperature control algorithm. b All mounting positions are permitted: v horizontal mounting (IMB5) v vertical mounting (IMV1 with shaft end at the top and IMV3 with shaft end at the bottom) in accordance with standard IEC 60034-7 Holding brake Lexium BMI servo motors can be equipped with an electromagnetic holding brake. d Do not use the holding brake as a dynamic brake for deceleration, as this will quickly damage the brake. Integrated encoder Lexium BMI servo motors are equipped with an absolute encoder. This encoder performs the following functions: b It gives the absolute position of the motor so that flows can be synchronized. b It measures the servo motor speed via the associated Lexium 32i integrated drive (this information is used by the drive's speed controller). b It measures the position information for the Lexium 32i position controller. b It sends data from the servo motor to the control unit, which provides automatic motor identification when the Lexium 32i starts. 4 encoder models are available: b High resolution SinCos Hiperface encoder: v single-turn (131,072 points/turn) (1) v multi-turn (131,072 points/turn x 4096 turns) (1) These encoders give an angular shaft position precise to less than 1.3 arc minutes. b Standard resolution SinCos Hiperface encoder: v single-turn (32,768 points/turn) (1) v multi-turn (32,768 points/turn x 4096 turns) (1) These encoders give an angular shaft position precise to less than 4.8 arc minutes.
