When the operation period in regeneration mode is continuous. add the following items to
the above calculation procedure in order to find the required capacity (W) for the
regeneration resistor.

Energy (J) for continuous regeneration mode operation period:
Eg = (2/60) Nmg x Tg x tg
Here:
Tg. Servomotors generated torque (N·m) in continuous regeneration mode operation period.
Nmg. Servomotors rotation speed (rev/min) for same operation period as above.
tg. Same operation period (s) as above.
 Energy (J) consumed by regenerative resistor:
Ek = Es - (El + Em + Ec) + Eg
 Required capacity (W) of regenerative resistor:
Wk = Ek / (0.2 x T)
