Calculation Of Positioning Frequency - Mitsubishi Electric MELDAS MDS-B-SVJ2 Series Specifications And Instruction Manual

11-4-2 Calculation of positioning frequency

Select the regenerative resistor so that the positioning frequency DP (times/minute) calculated by the
regenerative resistor capacity P
regenerative resistor is within the range shown in expression (11-11). With the unbalance axis, the
number of times for one cycle to raise and lower the axis is judged as DP.
DP < 48 ·
