*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.
***HIPERFACE® uses a serial interface to read absolute position before switching to sin/cos analog signals for incremental position feedback. Analog signals are interpolated at the drive and therefore, digital resolution is dependent on the drive.
****Refer to “Commissioning Rockwell Automation Drives with LDD 1800 Motors” for more information
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.
