§ Zero to peak currents, not RMS current.
Leakage Current
The servomotor is driven under the PWM control of an IGBT inverter in the amplifier.
This produces a high-frequency leakage current, which flows through the floating
capacitance of the motor winding, power cable and amplifier. This leakage current can
cause the malfunction of leakage detection circuit breakers or protective relays installed
on the power line.

Leakage Current per Motor
P20B 3.0mA

P50N 3.0mA
P60B 3.0mA
1.
When using two or more motors, add the leakage current of each motor to determine the system
leakage current.
2.
The table above assumes 2m cables. The leakage current will increase with longer cables and
decrease with shorter cables.
