Calculation Of The Positioning Frequency - Mitsubishi Electric MDS-D-SPJ3 Specification Manual

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
energy E (J) consumed by the regenerative resistor is within the range shown in expression (7-17). For
R
the unbalance axis, calculate using the regenerative energy E
the numbers of operation cycles for rising and lowering as DP.
