Schneider Drives

For speed control in processes without affecting their power systems, typically Schneider drives are used. Prior to utilizing a Schneider drive, things to consider are: mounting on the correct insulation class/length of cable to be connected to the drive (cable length); determining what method of control will be used to control the motor drive.

If a small pump or fan is used with basic parameters at the control panel and local control, you could use an ATV12 Drive; however, if the load has more variation or the drives will be communicating to a PLC panel, larger Altivar Drives with fieldbus modules and remote monitoring should be configured.

When selecting drive type to be utilized, the layout of the control panel is also important. If poor quality supply or long distance to the motor is experienced when selecting the size of the Input Protection Device, Line Reactor and Output Filtering, take this into consideration. Ensure that the internal enclosure has an open cooling path because the use of variable speed will heat an enclosure more than that of fixed speed motors would. Routing of shielded motor cables properly and utilising appropriate earthing practices will help reduce feedback-related disturbances to nearby instrumentation.

The configuration of these motors occurs in accordance with the use rather than factory defaults. The acceleration curve, deceleration method, torque boost value, and maximum allowable current are verified to the simulated load. Fault logs and diagnostics are pre-mapped to the HMI for rapid service response.

When utilizing these Schneider drives within US facilities, they will consistently keep the motor speed stable, provide control of inrush currents, and enable continuous data transfer with automation during the periods of rapid product change and irregular electrical supply conditions.
