The resolver is mounted and wired together with the JetMoves from Jetter AG in such a way that
the commutation offset equals 0°. The position values increase with positive setpoints when the
motor shaft (front view on motor shaft) rotates clockwise.
Different resolver sizes are used for different flange sizes. The electrical values are independent of
the resolver size.
The 2D drawings of the flange sizes JHNxx, JHQxx and JLxx show the dimensions for motors with
resolvers. The length changes with the brake option or other encoder types.
Jetter AG provides 2D and 3D drawings of motors with resolvers or other encoder options on their
homepage:

4.5 Derating at ambient temperatures higher than 40 °C
The speed/torque diagrams of the servo motors are given for an ambient temperature of up to 40°
C. For higher ambient temperatures, the values from this diagram must be multiplied by a derating
factor which can be taken from the derating table as a function of the temperature.
