4 SET-UP AND OPERATION
4.1. Basic Checks Before Commissioning
It is vitally important to ensure that the Coolvert that you have purchased is suitable for the supply that you intend to connect it
to, as is the importance of ensuring that this is appropriate for the motor to be connected to.
The motor nameplate data needs to be entered accurately before attempting to run the motor. The format of the information
can vary depending on the technology of the motor. It is very important to ensure that the data entered is in the correct format.
A common mistake is to enter an incorrect value for the back emf of a permanent magnet motor at rated speed as it can be
written as a peak voltage, rms voltage and phase to phase voltage, line voltage and so on.
4.1.1. Access to Parameters
