Phase Loss Detection Current Example
In this example, a 2198-H025-ERSx servo drive is paired with a
VPL-B1003T-C motor with 6.77 A rms rated current. Use the phase-loss
detection equation and table to calculate the initial minimum torque-proving
current as a percentage of motor rated current. Depending on the unique
characteristics of your application, the required torque-proving current value
can be larger than the initial recommended value.
