Current Amperage
The current amperage should be divided into the control power capacity and motor power capacity.
Each power supply should be input from the control power supply connector and the motor power supply
connector on the gateway unit. However, it is necessary that the 0V of the control power supply and the
motor power supply are in common.
The necessary capacity of the current amperage should be figured out by [Total of control power capacity of
used units] + [Total of motor power capacity of used actuators].
It is necessary that the rated current of 24V power supply satisfies the rated current of the motor power
capacity and the peak current satisfies the maximum current of the motor power capacity. However, when
several axes get connected, unless all the actuators operates at the same time, the rated current and
maximum current would not flow at the same time, thus the calculation should not be simply the total of all
the axes.
The specifications related to the power capacities should be as shown below.

If there is no fan unit equipped, operation can be performed
without derating in the temperature range between 0 and
40°C, but it is necessary to reduce the operation duty by 20%
in every 5°C in the temperature range between 40 and 55°C.
In case of fan unit equipped, operation can be performed
with no derating up to 55°C.
Restrictions in Unit Connection
(1) Number of 24V Driver Units to Connect
The maximum number of control axes to be connected should be 16 axes in the RCON system and 8
axes in the RSEL system.
From the structural perspective of the unit, it can accept connection without any upper limit, but make it
accept the number of axes described above of driver units at the maximum.
Have two gateway units or more in the construction when it is necessary to control number of axes
described above or more of actuators.
(2) Current Restrictions
Shown below is the restricting values of current for selecting calculation.
Check that the calculation result of the control power supply and motor power supply of each unit based
on the construction of RCON/RSEL system does not exceed the restricting values of current for selecting
calculation.
Also, the gateway units should not be included for the calculation.
Shown below is some examples for calculation.
[Control Power Supply] * The gateway units should not be included for the calculation.
Example 1
Actuator × 16 axes, All axes equipped with brake (2 axes/unit)
Driver unit (with brake) 0.6A × 8 = 4.8A ⇒ OK
Example 2
Actuator × 16 axes, All axes equipped with brake (1 axis/unit)
Driver unit (with brake) 0.4A × 16 = 6.4A ⇒ OK
Example 3
Actuator × 16 axes, All axes equipped with brake (2 axes/unit), All axes simple absolute type
Driver unit (with brake) 0.6A × 8 + Simple absolute 0.2A × 16 = 8.0A ⇒ OK
Example 4
Actuator × 16 axes, All axes equipped with brake (1 axis/unit), All axes simple absolute type
Driver unit (with brake) 0.4A × 16 + Simple absolute 0.2A × 16 = 9.6A ⇒ NG
[Motor Power Supply]
Example 5
RCON-PC (with PowerCON) × 16 axes
RCON-PC (with PowerCON) rated current 2.3A × 16 axes = 36.8A ⇒ OK
Example 6
When RCON-PCF × 16 axes or 6 axes
RCON-PCF rated current 5.7A × 16 axes = 91.2A ⇒ NG
RCON-PCF rated current 5.7A × 6 axes = 34.2A ⇒ OK
Example 7
RCON-PC (with no PowerCON), RCON-AC, RCON-DC
Rated current for all the units is low and it would not exceed current limit with 16 axes ⇒ OK
Example 8
RCON-PCF × 3 axes, RCON-PC (with PowerCON) × 7 axes, RCON-AC × 3 axes
5.7 × 3 + 2.3 × 7 + 1.3 × 3 = 37.1A ⇒ OK
Note When the operation pattern is to have all the axes operate acceleration and deceleration only and
the operation duty is 100%, it is necessary that the calculation is done with the maximum current
for the motor power supply.
