Step 2 : Calculate the effective regenerative power
Based on the calculation obtained during regeneration, check the regenerative capacity of the
regenerative resistor connected to the PY2 amplifier.
① For horizontal shaft driving
PM =
PM : Effective regenerative power [W]
EM : Regenerative energy at deceleration [J]
t o : Cycle time [s]
② For vertical shaft driving
PM =
PM : Effective regenerative power [W]
EM : Regenerative energy at upward driving, downward
driving and decelerated downward driving [J]
t o : Cycle time [s]
(2) Selection of external regenerative resistor
Compare the regenerative effective power obtained in steps 1 and 2 in (1) with the values in "9.5
External Regenerative Resistor Combination Table" and select an appropriate resistor.
