3.5 SERVOPACKs and Applicable Peripheral Devices
* 1. Nominal value at the rated load. The specified derating is required to select the appropriate molded-case circuit breaker.
* 2. Cut-off characteristics (25
°C): 200 % two seconds min. and 700 % 0.01 seconds min.
Note: 1. 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 for protection against overloads and short-circuiting,
or install an earth leakage breaker combined with a wiring circuit breaker for ground protection.
2. It is recommended to use a general-purpose circuit breaker of the rated current 200 mA or more, or a circuit
breaker for inverters (for high-frequency).
3.6 Main Circuit Wiring
• SJDE SERVOPACKs are suitable where the power supply is less than 5000 Arms (230 V max.).
• SERVOPACKs must be used with UL-listed fuses or circuit breakers, in accordance with the National Electrical
Code (NEC).
• Use 75
°C heat-resistant copper wires or an equivalent.
3.7 SERVOPACK Main Circuit Wire Size
Cable Types
• Wire sizes are selected for three cables per bundle at 40
°C ambient temperature with the rated current.
• Use cables with a minimum withstand voltage of 600 V for main circuits.
• If cables are bundled in PVC or metal ducts, consider the reduction ratio of the allowable current.
• Use heat-resistant cables under high ambient or panel temperatures where normal vinyl cables will rapidly deteri-
orate.
• Do not use cables under continuous regenerative state.
