Note 1 Refer to the separate booklet Controller Integrated Actuator for the details of the connected
actuator (ERC3).
Note 2 Rush current passes for about 50
μ
s after the power is injected.
For the calculation of 24V DC power capacity, figure out the numbers for (1) to (5) below, and then follow
Step (6).
(1) Control Power Current Consumption : 1A ·················································································1)
(2) Current Consumption of Motor Power Supply:
Sum total of load current + (Number of actuator axes equipped with brake × 0.15A) ················2)
(3) For Simple Absolute Type
: 0.2A + (0.3A × Number of axes) ····································3)
(4) Current Consumption at Excitation Phase Detection:
Add the inrush current for all connected axes············································································4)
(5) In-Rush Current :
60A················································································5)
(6) Selection of Power Supply:
Usually, the rated current is to be approximately 1.3 times higher than 1) + 2) + 3) above considering
approximately 30% of margin to the load current. However, considering the current of 4) to 5), even
though it is a short time, select a power supply with “peak load corresponding” type or that with enough
capacity. For the current of 4) to 5), it can be avoided from the current consumption occurred at the same
time by the timing for the emergency stop release (motor power-on) and servo-on being changed. In the
case that the capacity margin is not sufficient, voltage might be dropped in a moment. In particular, be
careful of the power unit with the remote sensing function.
(Note) Make short-circuit on 0V side when separate power sources are used for the control power and
motor power.
(Reference)
Selection of Power Supply Protection Circuit Breaker
It is recommended that the power supply protection is conducted on the primary side (AC power side) of
the 24V DC power supply unit.
Pay attention to the in-rush current of 24V DC power supply unit and rated cutoff current of the circuit
breaker.
• Rated Breaking Current > Short-circuit Current = Primary Power Supply Capacity/Power Voltage
• (Reference) In-rush Current of IAI Power Supply Unit PS241 = 50 to 60A, 3msec
