2.3 General Specifications
The general specifications of a ROBONET system are listed below.
Item Specification
Power-supply voltage
24 VDC ± 10 %
Power-supply current Varies depending on the system configuration.
Maximum number of connectable axes 16 axes (Controller units can be combined freely.)
Supported field networks CC-Link, DeviceNet, PROFIBUS, RS485 SIO
(slave station)
ROBONET communication protocol Modbus protocol
Component units GateWayR unit, controller unit, simple absolute R unit
ROBONET extension
(Refer to 2.2 for details.)
Emergency stop/enable operation The entire system is stopped by the emergency stop input from the GateWayR
unit. Each controller unit has a built-in drive-source cutoff relay.
Surrounding air temperature
0 to 40°C
Surrounding humidity 95% RH max. (non-condensing)
Protection degree IP20
External dimensions of each unit 34 W x 105 H x 73.3 D [mm]
All units have the same dimensions.
Interconnection of units Power-supply connection plate
Unit link cable or controller connection cable when the ROBONET communication
connection circuit board, simple absolute connection circuit board or ROBONET
extension unit is used (multi-stage layout or external SIO link)
Installation method Installation on a DIN rail (35 mm)
(However, controllers corresponding to external SIO link axes are excluded.)

*1 The current becomes the maximum during the excited-phase detection of the servo motor performed when the servo is
turned on for the first time following the power on. (Normal: Approx. 1 to 2 seconds, Maximum: 10 seconds)
*2 The current becomes the maximum during the excited-phase detection performed when the servo is turned on for the first
time following the power on. (Normal: 100 msec)
