Power Supply and Stop Circuit (Example)
In the diagram below shows a circuit related to REC system drive source cutoff. For REC system, 24V power is supplied
from the EC Gateway Unit, but the circuit related to the drive-source cutoff is on the EC Connection Unit side.
•
Each unit of EC Connection Unit possesses a drive cutoff circuit by semiconductor gathered for the four axes, and
the motor power source is to be cut off by the stop switch on the teaching pendant. Also, the drive source cutoff
circuit by semiconductor possesses features to detect the over current and to limit the in-rush current.
•
Each driver unit possesses an interface (Drive source cutoff connector: MPI/MPO) available for external drive
source cutoff prepared for each axis.
Note 1 If nothing is connected to the SIO connector, short-circuit should be made inside the controller.
Note
●
When externally shutting off the motor drive source, connect a contact such as a relay to the wiring between the
MPI* and MPO* terminals.
●
When supplying power by turning ON/OFF 24 VDC, leave 0 V connected and supply/cut off +24 V.
●
Make sure to have the right cable diameter and length that would not have the voltage dropped at the wiring of the
drive cutoff connector.
●
There may be a case of an alarm being generated because of the voltage drop at the controller power supply due to
inappropriate cable diameter or length. In such a case, adjust the output voltage of the power supply to keep 24V for
the supply to the controller.
Warning : Note that the stop switch on the teaching pendant cannot have a stop for the system side even though it
can have a stop for all the actuators connected to REC System.
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 24V power supply connector on the EC Gateway Unit.
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.
Note When ELECYLINDER * 4 axes are connected to EC Connection Unit
Restrictions in Unit Connection
(1) Number of EC Connection Units to Connect
The maximum number of control axes to be connected to one EC Gateway Unit should be 16 axes.
From the structural perspective of the unit, it can accept connection without any upper limit, but make it
accept 4 units (for 16 axes) of EC Connection Units at the maximum. (One unit occupies domains and
axis numbers for four axes regardless of whether to connect ELECYLINDER to the units or not.) Have
two EC Gateway Units or more in the construction when it is necessary to control 17 axes or more of actuators.
(2) Current Restrictions
Shown below is the restricting values of current for selecting calculation.
Item
Restricting Value of Current for Selecting Calculation
Control Power Supply (CP)
9.0A or less
Motor Power Supply (MP)
37.5A or less
Shown below is some examples for calculation.
[Control Power Supply] * EC Gateway Unit should be excluded from the target for calculation.
When ELECYLINDER × 16 axes: EC Connection Unit 0.1A × 4 = 0.4A
⇒
OK
[Motor Power Supply]
When ELECYLINDER (with power-saving setting inactivated) × 16 axes:
EC Connection Unit Rated Current 2.3A × 16 axes = 36.8A => OK
Note For the models with no description of the rated current for the motor current amperage, calculate with the
maximum current.
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.
REC system is capable to link 4 units (for 16 axes) at the maximum with the EC Gateway Unit allocated at
the left end as the interface for the field network connection and freely construct with combination of
multiple EC Connection Units. There is an order of allocation for each unit.

Each unit should be linked in the process shown below. (Make sure it gets linked before connected to the DIN rails.)
1) Twist the operation parts of the link upper parts and the link bottom parts towards the panel side and
place them at the panel side end.
2) Adjust the position of two units so the link upper parts come to Point [A], link bottom parts to [B] and the
four positioning bosses to [C] and all the six points fit to each other.
3) Once positioning is done, firmly insert the connectors at two points.
4) Twist the operation parts of the link upper parts and the link bottom parts towards the rear side till they
make click feeling.
