3.3 Precautions on Wiring
22
3.3.3 Caution for Cable
• For wiring, use the specified cables. Use cables that are as short as possible.
• Do not bend or apply tension to cables. The conductor of a signal cable is thin (0.08 to 0.12 mm
2
),
so handle the cables carefully.
3.3.4 Power Loss
Note: Values obtained with the servomotor rated output.
3.3.5 SERVOPACKs and Applicable Peripheral Devices
Note: It is recommended to use a general-purpose circuit breaker of the sensed current 200 mA or more, or a cir-
cuit breaker for inverters (for high-frequency).
* 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.
Ground Fault
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 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 ground fault detector for protection against overloads
