2 The ground protection circuit is designed for ground fault inside the motor windings while the motor is running.
Therefore, it may not protect the system under the following conditions.
• A low-resistance ground fault occurs between the main circuit cable and connector for the servomotor.
• The power supply is turned ON during a ground fault.
To configure a safer system, install an earth leakage breaker to protect against both overloads and shortcircuits, or install an
earth leakage breaker for ground protection and a molded-case circuit breaker.
