Appendix 2-2-2 Calculating the positioning frequency
Select the regenerative resistor so that the positioning frequency DP (times/minute) calculated from the
regenerative resistor capacity P
R (W) and regenerative energy ER (J) consumed by the regenerative
resistor is within the range shown in expression (2-10). For the unbalance axis, calculate using the
regenerative energy E
R per reciprocation operation, and judge the number of operation cycles for rising
and lowering as DP.
