Ground Monitoring

Description

When the power stage is enabled, the device monitors the motor phases for ground errors. A ground error occurs when one or more motor phases are short-circuited to the ground (earth) of the application.

A ground error of one or more motor phases is detected. A ground error of the DC bus or the braking resistor is not monitored.

If the ground error monitoring is deactivated, the drive may be rendered inoperable by a ground error.

NOTICE
INOPERABLE EQUIPMENT DUE TO GROUND ERRORS
  • Only deactivate ground monitoring during commissioning and only for test purposes.
  • Verify that the ground monitoring is active prior to putting the equipment into service.
Failure to follow these instructions can result in equipment damage.
