Power supply capacity
Power capacity is divided into two parts, control power capacity and motor power capacity.
24V DC power supply is to be input from the control power supply connector and the motor
power supply connector on the gateway unit. The user must make sure that 0 V of the control
and motor power is used in common.
The motor power supply to the 200V AC actuator is to be input from the 200V power supply unit
(RCON-PS2).
The necessary power capacity is calculated from adding the "total control power capacity of the
unit in use" and the "total motor power capacity of the connected actuator". However, the 200V
driver unit is to be calculated from the “sum-up of the control current amperage of used units”
and separated from the motor power supply.
The current rating for 24V DC power must exceed the total current rating for motor power
capacity, and the peak current must exceed the total motor power capacity. However, when
multiple axes are connected, provided that not all of the actuators' operation timing is the same,
the resulting value is not a simple total, because the rated current/maximum current do not flow
simultaneously.
Also, for the 24V system, “Calculator Software” is available that enables to automatically
calculate the necessary current amperage as soon as the actuator operation conditions and
operation patterns are set up.
Refer to “Calculator Instruction Manual (ME0381)” for details such as how to operate.
(Reference) Selection of Circuit Breaker for Power Supply Protection
[For 24V System]
It is recommended that protection of the power supply is performed on the primary side (AC power
source side) in the 24V DC power supply unit.
Be mindful of the in-rush current of the 24V DC power supply unit and the rated interrupting current
of the circuit breaker when select.
Rated Interrupting Current > Short-Circuit Current = Primary Side Current Amperage ÷ Power Supply Voltage
