COE Press Equipment’s latest ServoMaster Touch controller comes with a new larger 7” (178 mm) touchscreen, an additional Ethernet communications port and a host of tools that are particularly suited to the needs of roll formers. These roll form features include a stretch compensation tool. During roll forming, material can elongate or stretch. COE’s tool enables the user to enter the actual length of the stretched part, as well as the desired length. By pressing ‘accept’, the control applies a scaling factor to each step, thus compensating for any elongation.
Another feature is sequence mode. The ability to switch to sequence configuration permits the creation of multi-step jobs, enabling up to 50 steps per job to a total of 4000 steps of storage. Many applications that use sequence mode require a further new feature of the control – programmable outputs – which allows the addition of up to six programmable output cards (36 outputs) to a standard ServoMaster controller. Programmable outputs can be set to come on before, during or after the index, or not at all.
Interrupt is a function for roll forming applications that allows the mill to consume a loop of material after a punch operation. When the input is disabled by the roll form mill or other device, the controller pauses the index until the input is re-enabled. Once enabled, the feed will complete the index and resume operation.
Last but not least, FSP is a feature that enables the ServoMaster controller to close a contact and thus signal auxiliary equipment when each index is completed.
