I
nMAX
: The largest rated current while using servo drives of different specifications
C: Multiple of rated current (Note: The multiple is usually 1.5 to 2.5. If users are not sure about the multiple,
please use 1.5.)
C
MAX
: Multiple of the largest rated current of servo drive
K: Demand rate (Note: If users are not sure about the demand rate, please use 1.)
Example:
If three D1-N-18 and one D1-N-36 servo drives are used:
We assume C and C
MAX
are 2.
Do not power on at the same time: I

= (3×6+12-12)×1 + 12×2 = 42 A

4.3 Regenerative resistor and DC link (X2)
When motor decelerates, it generates energy. The energy returns to the capacitors of the servo drive.
When the returned energy exceeds the capacity of the capacitors, regenerative resistor must be installed
to protect the servo drive by absorbing the returned energy. D1-N-09, 18 and 36 servo drives have one
internal regenerative resistor (50 Ω/150 W), but D1-N-90 servo drive does not have internal regenerative
resistor. For fast movement (Regenerative energy is larger than 150 W.), external regenerative resistor
must be installed since the internal regenerative resistor cannot absorb all the returned energy.
