Safety Considerations with Variable Speed Drives

October 13, 2023

Variable speed drives, also known as VSDs or variable frequency drives (VFDs), are electronic devices that regulate the speed of an electric motor by adjusting the frequency and voltage supplied to it. It consists of three main components: an AC-to-DC converter that converts incoming AC power to DC power, a DC bus that stores this converted power, and an inverter that converts the stored DC power back into AC power with adjustable frequency and voltage. We’ll explore safety considerations when working with these powerful devices!


Safety procedures associated with variable speed drives


1. Lockout/Tagout Procedures:

Lockout/Tagout Procedures are crucial when working with variable speed drives. These procedures ensure the safety of employees and prevent accidents or injuries. It is important to understand what lockout/tagout means. Lockout involves physically disabling the power source of a machine or equipment, while tagout involves placing a visible warning tag on the equipment to indicate that it should not be operated. Before performing any maintenance or servicing tasks on variable-speed drives, it is essential to follow lockout/tagout procedures. This ensures that the drive cannot accidentally start up while someone is working on it.


2. Emergency Procedures:

Emergency procedures are a crucial aspect of ensuring safety when working with variable-speed drives. These procedures outline the steps that should be taken in the event of an emergency, such as a power outage or equipment malfunction. First and foremost, it is important to have clear and easily accessible emergency shutdown controls for all variable speed drives. These controls should be clearly labelled and located in close proximity to the equipment.


3. Employee Training:

When it comes to the safety considerations with variable speed drives, employee training is of utmost importance. By providing comprehensive and ongoing training programs, companies can ensure that their employees are equipped with the knowledge and skills necessary to operate variable-speed drives safely.
