Notes: |
Supports motor design types NEMA A, B, C, D & E and IEC type H and N. Rated torque is calculated from rated power and rated speed. Update rate of Motor Measurements is 1x per second. Default Trend duration is 1 week. |
1Add 5% error when selecting Motor design type Other Specification valid for Motor Power > 30% of rated power Specification valid at stable operating temperature. Run the motor for at least 1 hour at full load (2-3 hours if the motor is 50 HP or higher) to obtain stable temperature |
