4.2 Determining the “Mechanical to electrical ratio”
experimentally
The parameter 8020:13 “Mechanical to electrical ratio“ [
}
47] is an essential parameter for the operation of
EP7402-0057. You can calculate the parameter [ } 31] , if the number of poles and the gear ratio are known.
Otherwise you must determine the parameter experimentally:
1. Set the parameter 8023:03 "Disable motor diagnosis" to TRUE.
2. Set "Velocity" to 0.
3. Set "Enable" to 1.
ð
A motor phase is powered.
ð You may hear a "click" noise from the roller motor.
4. Rotate the conveyor roller by hand. Do you feel defined snap steps?
- Yes: Continue below
- No: Increase the value of parameter 8023:14 "Sensorless offset voltage" by 10
dec
and try again.
5. Rotate the conveyor roller by 360° by hand and count the number of snap steps.
Tip: Make a mark on the roller. This makes it easier to rotate the roller by exactly 360°.
6. Set the output variable "Enable" to 0.
7. Set the parameter 8023:03 "Disable motor diagnosis" back to FALSE.
8. Enter the number of snap steps in parameter 8020:13 "Mechanical to electrical ratio".
