Capacitive Current Coupling
High speed voltage switching causes AC coupling from motor cables to ground
terminal/protective earth. The current produced by this coupling is referred to as
capacitive current. The drive current is the combination of capacitive current and
motor current. Because motor current is monitored for overload protection, the
table below lists the maximum cable length recommendations that will assure a
capacitive current error of less than 15 percent.
Cable Length Recommendations — Capacitive Current Table 2.F
➊
Not recommended for use above 4 kHz PWM Frequency.
➋
When using shielded cable at lightly loaded conditions, cable length recommendations for drives rated 0.75 kW (1 HP) and
below are 61 meters (200 feet).
➌
Not recommended for 230V applications.
