2.4.5 Connecting the emergency stop circuit
Before using the ROIbot, always connect the emergency stop circuit to the enclosed input/output
connector. If this circuit is not connected, the controller will enter the emergency stop state.
For details, refer to section 10.1.2 (1).

2.4.6 Effect of leakage current
This controller (master unit, slave unit) controls the motor assembled into the axis with PWM
(Pulse Width Modulation). Thus, a high frequency leakage current (Cf·dV/dt) that do not affect
the human body will flow through the cable from the controller to motor and the motor's floating
capacity (Cf). General leakage breakers, excluding those for high frequencies, normally detect
the leakage current at the same level between the low frequency and high frequency
regardless of the frequency zone. Thus, the leakage breaker will function when the leakage
current in the high frequency zone exceeds the operating frequency of the leakage breaker.
Measures when leakage breaker functions needlessly by high frequency leakage current
(1) Use a high frequency and surge corresponding leakage breaker.
Use a leakage breaker that is sensitive to the high frequency element leakage breaker
contained in the controller's leakage current to prevent needless functioning.
(2) Decrease the floating capacity between the controller and ground.
Select as short a controller cable as possible to be used between the controller and axis.
Always ground the controller with Class 3 or higher grounding (grounding
resistance 100

or less) to prevent electric shock accidents.
Needless functioning of the leakage breaker could occur in a separate
system that is not directly related to the circuit connected to the controller
because of leading in of the leakage current.
