ME0392-4C
Limit in Number of Axes due to Input Power to 200V Power Supply Unit
For the actuators below, there should be a limit to the number of axes connectable due to the
power supply provided to the 200V power supply unit connected to RCON-SC-1.
Item
200V Motor power supply
(3-Phase) (Single-Phase)
DD (A)-LT18 (C) / T18 (C)
Max. 8-Axis (RSEL Max.
number of axis)
Cannot Connect
DD (A)-LH18 (C) / H18 (C) Max. 2-Axis Cannot Connect

Max. 8-Axis (RSEL Max.
number of axis)
Cannot Connect
RCS3-CT8C Max. 3-Axis Cannot Connect
If you would like to have more axes than the maximum number of axes to be connected,
enlarge the capacity by connecting the connection type SCON-CB RCON to the extension unit.
Calculation examples are shown below.
[200V System Motor Power Supply]
Ex. 10
1 axis of actuator each of 200W, 300W and 600W motors
200W × 1 axis + 300W × 1 axis + 600W × 1 axis = 1,100W
⇒
Single-Phase OK , 3-Phase OK
Ex. 11
RCS-CTZ5
×
1 axis, actuator of 200W motor
×
7 axes
RCS3-CTZ5C is not capable of use in single-phase
⇒
Single-Phase NG ,
120W + 200W × 7 axes = 1,520W
⇒
3-Phase OK
Ex. 12
Actuator of 200W motor
×
6 axes, LSA-S10SM (Multiple Slider)
×
1 axis
200W × 6 axes + 600W × 2 ＝ 2,400W
⇒
Single-Phase NG ,
200W × 6 axes + 200W × 2 ＝ 1,600W
⇒
3-Phase OK
Ex. 13
Actuator of 400W motor × 8 axes
400W × 8 axes = 3,200W
⇒
Single-Phase NG , 3-Phase NG

(3) Number of Connectable Axes in 200V EC Type
For actuators with 200V EC specifications has restrictions regarding the DC power supply
(PSA-200) for drive a motor are as shown below.
Specifications
Max. number of
connectable axes
Max. motor wattage of
connectable
100V AC power supply
specifications
6 axes 800W
200V AC power supply
specifications
6 axes 1,600W
The number of axes that the total of the motor wattage of connected ELECYLINDER would not
exceed the restricted values in the table above can be connected. However, Max. number of
connectable axes is 6 axes.
The motor wattage of ELECYLINDER should be as described below.
Model Motor wattage
EC- S10□
EC- S10X□
100W
EC- S13□
EC- S13X□
200W
EC- S15□
EC- S15X□
400W
Caution
The maximum length of the motor power supply cable CB-EC- PW□□□ -RB between the
main unit of ELECYLINDER and the motor drive DC power supply PSA-200 is 10m.
Even though the maximum number of connectable axes is 6 axes, the motor power supply
cable may not reach depending on the layout of the unit of ELECYLINDER.
Be aware that an additional unit of the DC power supply for motor drive PSA-200 is
needed in case the cable does not reach.
