Rotational energy is proportional to inertia. At high speeds a high inertia means lots of regen R wattage needed. However, from the above example, once the speed is low enough so that the copper losses (from a full torque acceleration) are the same as the rotational losses, the copper losses also increase in proportion to the inertia. This is because if inertia increases by ‘n’ it takes ‘n’ times longer to decelerate. If the speed is not too high, even with a high inertia, external regen may not be needed. Counter-intuitively the greatest need for external regen is when the decelerating torque is low and the speed is high. In summary, the need for regen is a strong function of maximum motor speed. Below some speed, roughly (1/3 to 1/4) system rated speed, an external regen resistor is unlikely to be needed.

The PC830 servo drive can commutate a motor

using any one of the following feedback devices: • Resolver • Incremental Encoder • Comcoder (hall/encoder).With the motor disabled, rotate the shaft in the clockwise direction as viewed from the shaft end (as shown in the picture below).If EncPos decreases as the shaft is rotated, swap A and A connections and repeat Step 3. 5. Click on the Create New Configuration button. Select the proper motor, drive, and desired mode of operation. Click on Next.

Incremental encoders are not absolute feedback devices. 

Therefore, an alignment procedure must be performed. The motor should perform its encoder alignment check upon power up AND assertion of the hardware enable. For additional information on incremental encoder alignment consult the online help of the PC830 software “Encoder Alignment Overview” or contact Pacific Scientific Applications Engineering for assistance.Enter the correct encoder line count. 8. Click on Save to File and give the configuration a name. 9. Click on Download to Drive to send the complete configuration to the drive. 10. After the download is complete, click on YES to save the configuration to non-volatile memory. 11. Turn AC power OFF and then ON again.
