Assume that the load inertia is N times the motor inertia, and when motor decelerates from
3000 rpm to 0, the regenerative power is (N+1) × Eo and the regenerative resistor needs to
consume (N+1) × Eo
－ Ec joules. Assume that the reciprocate operation cycle is T sec, then the
required power of regenerative resistor = 2× （ (N+1) × Eo － Ec ） / T.
The calculation is as follows:
Step What to do Calculation and setting method
1
Set the capacity of the regenerative
resistor to the maximum.
Set P1.053 to the maximum value
2 Set the operation cycle (T) Manual input
3 Set the rotation speed (wr) Manual input or read the status with P0.002
4 Set the load / motor inertia ratio (N) Manual input or read the status with P0.002
5
Calculate the maximum regenerative
resistor (Eo)
Eo= J * wr

6
Find the regenerative power that can be
absorbed by the capacitor (EC)
Refer to the table above
7
Calculate the required capacity of the
regenerative resistor
2 × （ (N+1) × Eo － Ec ） / T
