*Assumes a 90°C rise from an ambient temperature of 20°C with motor mounted to listed aluminum heatsink or equivalent.
**Mass varies slightly by encoder type. Specifications assume configuration with largest mass.
Specifications are rated assuming a 20C ambient temperature. Increasing the ambient temperature derates the motor performance.
All electrical and performance specifications have +/- 10% tolerance. Specifications are preliminary and subject to change.
