*1 In-rush current will flow for approximately 20msec after the power is turned on (at 40°C).
Note that the value of in-rush current differs depending on the impedance of the power supply line.
*2
Leak current varies depending on the capacity of connected motor, cable length and the surrounding environment. Measure the
leak current at the point where a ground fault circuit interrupter is to be installed when leakage protection is conducted.
A ground fault circuit interrupter needs to be selected carefully considering the purposes of prevention of fire and
protection of human.
Use the harmonic type (for inverter) for the ground fault circuit interrupter.
*3 It is not necessary to supply power to PIO when operating with using ROBONET, Gateway Unit or SIO Converter
without using PIO. In this case, set the parameter No. 74 (PIO Power Supply Monitor) to “1” (Invalid). It will generate
the error code No. 0CF (I/O 24V Power Supply Error) if the setting is not done.

Selection of Circuit Interrupter
• 3 times of the rated current flows to the controller during the acceleration/deceleration. Select an interrupter that does not trip
with this value of current. If a trip occurs, select an interrupter that possesses the rated current of one grade higher. (Refer to
the operation characteristics curves in the product catalog.)
• Select an interrupter that does not trip with the in-rush current. (Refer to the operation characteristics curves in the product
catalog.)
• Consider the current that enables to cutoff the current even when a short circuit current is flown for the rated cutoff current.
Rated Interrupting Current > Short Circuit Current = Primary Power Capacity / Power Voltage
Consider margin for the rated current on the circuit breaker.

Installation Environment, Storage Environment
This product is capable for use in the environment of pollution degree 2*1 or equivalent.
*1 Pollution Degree 2: Environment that may cause non-conductive pollution or transient conductive
pollution by frost (IEC60664-1)
1. Installation Environment
Do not use this product in the following environment
• Location where the surrounding air temperature exceeds the range of 0 to 40°C
• Location where condensation occurs due to abrupt temperature changes
• Location where relative humidity exceeds 85%RH
• Location exposed to corrosive gases or combustible gases
• Location exposed to significant amount of dust, salt or iron powder
• Location subject to direct vibration or impact
• Location exposed to direct sunlight
• Location where the product may come in contact with water, oil or chemical droplets
• Environment that blocks the air vent [Refer to Installation and Noise Elimination]
When using the product in any of the locations specified below, provide a sufficient shield.
• Location subject to electrostatic noise
• Location where high electrical or magnetic field is present
• Location with the mains or power lines passing nearby
2. Storage and Preservation Environment
The storage and preservation environment should comply with the same standards as those for the
installation environment. In particular, when the machine is to be stored for a long time, pay close
attention to environmental conditions so that no condensation forms. Unless specially specified,
moisture absorbency protection is not included in the package when the machine is delivered. In
the case that the machine is to be stored and preserved in an environment where condensation is
anticipated, take the condensation preventive measures from outside of the entire package, or
directly after opening the package.
Installation and Noise Elimination
1. Noise Elimination Grounding (Frame Ground)
2. Precautions regarding wiring method
1) Wire is to be twisted for the 24V DC power supply.
2) Separate the signal and encoder lines from the power
supply and power lines.
3. Noise Sources and Elimination
Carry out noise elimination measures for power devices on
the same power path and in the same equipment.
The following are examples of measures to eliminate noise
sources.
1) AC solenoid valves, magnet switches and relays
[Measure] Install a Surge absorber parallel with the coil.
2) DC solenoid valves, magnet switches and relays
[Measure] Mount the windings and diodes in parallel.
Select a diode built-in type for the DC relay
4. Heat Radiation and Installation
Design and Build the system considering the size of the controller box, location of the controller and
cooling factors to keep the ambient temperature around the controller below 40°C

● Wiring for Emergency Stop Input
The following diagram shows an example of how the emergency stop switch for the teaching pendant may be
included in the emergency stop circuit you may construct.
Note 1 When the tea ching pendant is not connected, S1 and S2 become short-circuited in side the controller.
Note 2 Connect a contactor to L1 and L2 terminals for external power cutoff by the emergency stop if the motor power is
required to be cut off externally to comply with the Safety Categories.
Note 3 The rating for the emergency stop signal to turn ON/OFF at contact CR1 is 24V DC and 10mA.
Note 4 For CR1, select the one with coil current 0.1A or less.
