1500W R88M-G1K520T-B-Z OMRON AC Servo Motor the current consumption of other controllers

Maximum Input Current:

The Servo Drive's maximum momentary output is approximately three times the rated output, and
can be output for up to three seconds.
Therefore, select no-fuse breakers with an operating time of at least five seconds at 300% of the
rated current. General-purpose and low-speed no-fuse breakers are generally suitable.
Select a no-fuse-breaker with a rated current greater than the total effective load current of all the
Servomotors. The rated current of the power supply input for each Servomotor is provided in Main
Circuit and Servomotor Connector Specifications .
Add the current consumption of other controllers, and any other components, when selecting the
NFB.

Inrush Current:

The following table lists the Servo Drive inrush currents.
With low-speed no-fuse breakers, an inrush current 10 times the rated current can flow for
0.02 second.
When multiple Servo Drives are turned ON simultaneously, select a no-fuse-breaker with a 20-ms
allowable current that is greater than the total inrush current, shown in the following table.

Leakage Breakers

Select leakage breakers designed for protection against grounding faults.
Because switching takes place inside the Servo Drives, high-frequency current leaks from the
switching elements of the Servo Drive, the armature of the motor, and the cables.
High-frequency breakers with surge withstand capability do not detect high-frequency current,
preventing the breaker from operating with high-frequency leakage current.
When using a general-purpose leakage breaker, use three times the sum of the leakage current
given in the following table as a reference value.
When selecting leakage breakers, remember to add the leakage current from devices other than
the Servomotor, such as machines using a switching power supply, noise filters, inverters, and so
on. To prevent malfunction due to inrush current, we recommend using a leakage breaker of ten
times the total of all current values.
The leakage breaker is activated at 50% of the rated current. Allow leeway when selecting a
leakage breaker.
For details on leakage breakers, refer to the manufacturer’s catalog.
The following table shows the Servomotor leakage current for each Servo Drive model.

Surge Absorbers

Use surge absorbers to absorb lightning surge voltage and abnormal voltage from power supply
input lines.
When selecting surge absorbers, take into account the varistor voltage, the allowable surge
current and the energy.
For 200-VAC systems, use surge absorbers with a varistor voltage of 620 V.
The surge absorbers shown in the following table are recommended.
