System Design and Installation
Servo Driver inrush current:
With low-speed no-fuse breakers, an inrush current 10 times the rated current flows for 0.02 sec-
onds. For a simultaneous inrush for multiple Servo Drivers, select a no-fuse-breaker with a 20-ms
allowable current greater than the total inrush current shown in the following table for the applicable
Servomotor models.
● Surge Absorbers
Use surge absorbers to absorb surges from power supply input lines due to lightning, abnormal volt-
ages, etc. When selecting surge absorbers, take into account the varistor voltage, the amount of
surge immunity, and the amount of energy resistance. The surge absorbers shown in the following
table are recommended.
Note 1. Refer to the manufacturers’ documentation for operating details.
Note 2. The surge immunity is for a standard impulse current of 8/20
µs. If pulses are wide, either
decrease the current or change to a larger-capacity surge absorber.
● Noise Filters for Power Supply Input
Use the appropriate noise filter from among those in the following table for the Servo Driver power
supply.
Note The last 2 digits in the noise filter’s model number indicate the type of connection terminals
used. “07” indicates lead-wire terminals. There are also models with soldered faston terminals
(“06”) and screw terminals (“08”). Use the appropriate noise filter for the application. For
details, contact the manufacturer.
