Default setting: Ascending position values when looking at the flange and rotating the shaft clockwise. Parameter defining the steps per turn as well as the total resolution. Description Screen: connected to housing Parameter for setting the encoder to a requested position value assigned to a defined shaft position of the system. The offset of encoder zero point and mechanical zero point is stored in the encoder. Scaling Signals General informations Self-heating interrelated to speed, protection, attachment method and ambient conditions as well electronics and supply voltage must be considered for precise thermal dimensioning. Self-heating is supposed to approximates 6 K (IP 65 protection) respectively 12 K (IP 67 protection) per 1000 rpm. Operating the encoder close to the maximum limits requires measuring the real prevailing temperature at the encoder flange. 3 www.baumer.com/motion 13/8/2015 Bus protocol Core colour Absolute encoders - bus interfaces Blind hollow shaft up to ø15 mm Magnetic single- or multiturn encoders 12 bit ST / 18 bit MT, CANopen® BMSH 58, BMMH 58 CANopen® - MAGRES Dimensions 19.7 32 6 (4x) ø31 23 ø42 Detail A 0 ø50 -0.025 ø50 -0.025 ø58 ø58 0 BMSH/BMMH 58 - cable radial, IP 65 15.5 2 A 6.5 15.5 2.2 A 2 M4 (4x) 1 1 øD H7 25 25 60 12 ° 0° 0° 2.2 øD H7 12 0° ° Detail A 35.4 BMSH/BMMH 58 - cable radial, IP 67 12 60 ° 12 0 1 øD H7 24 M12 6 (4x) 6.5 2 A M4 (4x) ø31 ø42 2.2 15.5 M4 (4x) 1 12 0° 2 A M12 60 12 ° 0° 2.2 15.5 øD H7 24 12 0° 60 12 ° 0° BMSH/BMMH 58 - connector M12 radial, IP 67 M4 (4x) BMSH/BMMH 58 - connector M12 radial, IP 65 6 (4x) ø42 ø31 Detail A 32 ø42 6.5 0 ø50 -0.025 ø50 -0.025 ø58 ø58 0 Torque pin support 23 35.4 6 (4x) 6.5 Detail A Bore torque pin 60 ° 12 ±1 ø3 ° 60 2.4 20 7.5 ±1 17 4 www.baumer.com/motion Subject to modification in technic and design.
