Joliet Technologies tests all Drives at no load, prior to shipment, to insure that all of the operator’s functions work correctly, and are capable of providing rated armature and field voltages. We will set as many parameters as possible in order to minimize your start-up time. However, it will be necessary to retune your drive for the dynamics of your mechanical system, the electrical power source and other variations, which must be taken into account for the drive to function correctly. Joliet Tech’s Service Engineers are available to provide this service in accordance with our standard published rates.

Start-up assistance is not provided with this quotation, but it is available at the standard published rates. The customer will be required to have ALL equipment and all necessary electrical connections hooked up according to the requirements of the local electrical code. In the event that there is a failure related to the customer-supplied equipment, or the system is not ready for start-up, the customer will be responsible for all incurred expenses and time of the service technician, (ex: stand-by time).
