5.10: The Calculate Function
The Calculate function uses programmed motor and encoder values to calculate initial
gains and limits. These can be modified to fine-tune the amplifier. Follow the steps below:
1
Click Calculate to calculate and display the settings.
2
Verify the peak current limit, continuous current limit, and velocity loop velocity limit.
If one or more of these values seems inappropriate, click Cancel and check: Peak
Torque (or Force), Continuous Torque (or Force), Velocity Limit, and Torque (or Force)
Constant. Correct them if needed. See Rotary Motor Setup Parameters (p. 44)
or Linear Motor Setup Parameters (p. 45).
If the Motor/Feedback values were correct but the peak current limit, continuous current
limit, or velocity loop velocity limit values are not optimal for the application, change
these limits during the tuning process.
3
Load the values into amplifier RAM by clicking OK.
NOTE: When loading motor data from a file, if the motor wiring configuration in the
motor file does not match the configuration currently stored in the amplifier, CME
prompts for verification on which configuration to use. Select the file configuration by
clicking Yes. The configuration will be tested as part of Motor Phasing (p. 93).
