The input voltage readings should be within 1% of one another when measured from phase to phase with no load. Drive measurementsĪny good quality True RMS multimeter can verify proper input power to an ASD. Now, technicians won't have to guess whether the drive is operating correctly and delivering the correct voltage, current, or frequency for a given control setting. Incorporates a selectable low pass filter* that allows for accurate drive output measurements that agree with the motor drive controller display indicator.
But until now, there hasn't been a digital multimeter on the market able to accurately measure ASDs. This is especially true when taking voltage, frequency, and current measurements on the output side of the motor drive. Likewise, choosing the right test tools for troubleshooting the drive, the motor, and the connections are of utmost importance. Nobody takes inaccurate measurements on purpose, but it's easy to do, especially when working in a high-energy, noisy environment like an ASD. As you go, take care to take accurate measurements. A lot of time and money can be wasted replacing perfectly good parts when the problem is simply a loose connection. The most efficient troubleshooting procedure begins at the motor and then works systematically back to the electrical source, looking for the most obvious problems first. The trick is tracking it down quickly and keeping downtime to a minimum. Technicians use many different methods to troubleshoot an electrical circuit, and a good troubleshooter will always find the problem - eventually.
