Cause: There is a short circuit between the motor output phase and the earth ground.
Fix: Increase the deceleration time (). Enable Stall Prevention during deceleration ( L3-04 = 1 ). Install a dynamic braking resistor if fast deceleration is mandatory. Uv1 (Under-voltage)
Ground the drive according to local electrical codes to minimize noise and ensure safety. Control Circuit Wiring
Yaskawa provides a suite of documents for the V1000-4X, each serving a specific purpose. Understanding which manual you need is the first step to a successful project. The documentation that ships directly with the V1000-4X includes: yaskawa v1000x manual
In the quiet hum of a bustling factory, there was a drive that everyone trusted—the . It wasn't the largest machine in the plant, but it was known as the world’s smallest compact drive in its class. While other machines struggled in tight spaces, the V1000 thrived, often installed side-by-side to save up to 70% of enclosure space.
For more complex troubleshooting, features like the Verify Function allow you to list all parameters that have been edited or changed from their default settings, which is a great way to identify the root cause of a problem.
Connect these terminals directly to the motor. Never connect main power lines to these terminals, as it will permanently damage the drive. Cause: There is a short circuit between the
Maintain at least 30 mm (1.18 inches) of space on the sides and 100 mm (3.94 inches) at the top and bottom of the drive for proper airflow.
The Yaskawa V1000X builds upon the legendary reliability of the standard V1000 platform, incorporating advanced features for both Open Loop Vector control and V/f control. It is designed to handle both industrial induction motors and permanent magnet synchronous motors (PM motors). Key Features
Three-phase motor output connections. Never connect AC main power to these terminals, as it will destroy the drive. +, -: DC bus terminals for dynamic braking units. B1, B2: Direct connections for a braking resistor. Control Circuit Terminals: Install a dynamic braking resistor if fast deceleration
Turn off all main power inputs before wiring.
Enter the base frequency (usually 50.0 or 60.0 Hz) in T1-05 .
