Cause: The input power dropped below acceptable levels, or a phase loss occurred.
The V1000-X can output lethal DC bus voltage even when the input power is off. The manual emphasizes:
When the drive detects an irregularity, it displays a fault code on the LED operator and shuts down output to protect the system. Common Faults and Solutions
Ensure ambient temperatures remain between -10°C and +40°C for NEMA 1 enclosures, or up to +50°C for IP20 open-chassis setups. Orientation: Always mount the drive vertically. Power Section Wiring
To maximize torque performance under Open Loop Vector control, perform a rotational or stationary Auto-Tune:
When a fault occurs, the V1000X stops output current to protect itself, and a code flashes on the display. Below are the most common fault codes found in the technical manual: Common Error Codes
