Part 1 Installation
*2 The number of fan units varies depending on the controller specification.
The number of fan units varies as follows in accordance with the number of controller axes (whether or
not linear movement axis is added) and use/no-use of any expansion I/O board.

*3 For a SCARA robot with an arm length of 500 mm or more, two axes come with a brake.
For a SCARA robot with an arm length of 250 to 350 mm, one axis comes with a brake.
For a SCARA robot with an arm length of 120 or 150 mm, a brake is optional.
(If the system has a linear movement axis with brake, this brake is provided in addition to the brake(s)
for the SCARA axis(es).)
[1] Control power source capacity
The power source capacity of the control power supply is obtained by applying the efficiency
coefficient and power factor to the sum of all power consumptions of controlled units, based on the
applicable values shown in the table.
[2] Heat output of the control system
The heat output of the controller’s control system is obtained as the total sum of all internal power
consumptions of controlled units and internal power consumptions of external power sources, based
on the applicable values shown in the table.
[3] I/O power-source capacity
The I/O power source capacity (24 VDC) is obtained as the total sum of all power consumptions of
external power sources for DIO cards.
[4] Brake power source capacity
The brake power source capacity (24 VDC) is obtained as the total sum of all power consumptions of
external power sources for brakes.
Control power source capacity [VA] = 6 (Power consumption of each controlled unit x Quantity) y
0.7 (Efficiency coefficient) y 0.6 (Power factor)
Heat output from control system [W] =
6 (Internal power consumption of each controlled unit x Quantity) + 6 (Internal power
consumption of each external power source x Quantity).
I/O power source capacity [W] =
6 (Internal power consumption of each external power source for DIO x Quantity)
Brake power source capacity [W] =
6 (Power consumption of each external power source for brake x Quantity)
