Introduction

Parker and PA20 variable frequency drives are commonly used in industrial applications to regulate the speed of electric motors. These drives are designed to provide efficient and reliable operation， but sometimes they can encounter issues and generate alarms. In this article， we will discuss the common alarms associated with Parker and PA20 variable frequency drives and how to troubleshoot them.

Common Alarms for Parker Variable Frequency Drives

1. Overvoltage Alarm

The overvoltage alarm is generated when the input voltage exceeds the specified range. This can be caused by issues with the power supply or incorrect wiring. To troubleshoot this alarm， check the power supply and ensure that the wiring is correct.

2. Undervoltage Alarm

The undervoltage alarm is generated when the input voltage falls below the specified range. This can be caused by issues with the power supply or incorrect wiring. To troubleshoot this alarm， check the power supply and ensure that the wiring is correct.

3. Overcurrent Alarm

The overcurrent alarm is generated when the output current exceeds the specified range. This can be caused by issues with the motor or the load. To troubleshoot this alarm， check the motor and the load and ensure that they are operating within the specified range.

4. Overtemperature Alarm

The overtemperature alarm is generated when the temperature of the drive exceeds the specified range. This can be caused by issues with the cooling system or improper installation. To troubleshoot this alarm， check the cooling system and ensure that the drive is properly installed.
