Siemens introduces the 1FT7, a line of high-performance servo motors for such demanding motion control applications as machine tool CNC interpolation, production machine indexing control and more. Their use results in higher dynamic response, due to a 30% shorter design and 4x overload capacity versus 3x on the predecessor family of servos. Less downtime also results from the rigid vibration-insulated encoder mounting, which also enables the OEM or end user to exchange the encoder in the field in less than five minutes, without encoder alignment.
Design engineers have a choice in selecting this servo, as it is available in air-cooled, forced ventilation and water-cooled designs. The water-cooled design of the 1FT7 is provided with stainless steel piping in the stator.
Start-up and commissioning personnel will appreciate the Siemens electronic nameplate and digital encoder interface on this new servo, DRIVE CLiQ, as it simplifies start-up or replacement by not requiring all electronic data to be entered, as the DRIVE CLiQ cable recognizes all drive system components. With this feature, these motors become essentially plug-n-play devices. The drive recognizes the motor automatically and optimizes the parameterization accordingly. This digital encoder interface further allows users to route all their different encoder types along one signal cable.
High-resolution encoders, currently 22 bit, enable these servos to become highly precise motion control system components and these new high-dynamic 1FT7 motors also feature very low rotor inertia, thereby making them practical in applications where it was previously impossible to drive a servo. Such applications include sorters in the printing industry, which previously required mechanical cams but can now utilize electronic cams for better energy efficiency and less wear.

No. 1018 is an electrically-heated, 500º F (~260ºC) three-zone belt conveyor oven from Grieve, currently used for drying ceramic parts. Workspace dimensions are 18” wide x 40’ deep x 18” high. 180 KW (60 KW per zone) are installed in Incoloy-sheathed tubular heating elements, while three 3-HP recirculating blowers (total 12,600 CFM) provide vertical downward airflow to the workload. The oven was split into three sections for shipment.
The unit contains a 12” wide, 1/2” stainless steel flat wire conveyor belt with 1/3-HP motor drive, variable from 2 to 30 inches per minute and has a 30” long open belt loading zone and a 60” long open unloading zone.
This Grieve conveyor oven features 4” insulated walls, aluminized steel exterior and Type 304, 2B finish stainless steel interior, three independent doors for access to the workspace, three 325 CFM powered forced exhausters and the unit was built to NEMA 12 electrical standards. It has disposable fresh air filters in each zone, including photohelic pressure gauges with alarms.
Controls onboard No. 1018 include SCR power controllers and independent recirculated airflow and temperature controls for each of three 162” insulated heat zones.
