7-3 Selection of the regenerative resistor
7-3-3 Calculation of the positioning frequency
Select the regenerative resistor so that the positioning frequency (deceleration stopping frequency for
spindle) DP (times/minute) calculated from the regenerative resistor capacity P
R
(W) and regenerative
energy E
R
(J) consumed by the regenerative resistor is within the range shown in expression (7-17). For
the unbalance axis, calculate using the regenerative energy E
R
per reciprocation operation, and judge
the numbers of operation cycles for rising and lowering as DP.
