GE VMIVME-2128 Mobile DCS storage unit

GE Intelligent Platforms has announced the latest firmware release of its advanced motion controller, the GE VMIVME-2128. Regardless of how many axes of motion there are, the GE VMIVME-2128 is capable of controlling up to 40 simultaneous axes of motion with absolutely identical 1ms servo-loop update times. At the same time, the

GE is becoming the motion controller of choice for a range of new areas such as packaging, material handling and automated assembly. Users will find that PACMotion can serve even more applications by connecting it to a wide range of off-the-shelf equipment, thereby reducing system costs.
GE supports two analogue signal axes that can control one or two third-party amplifiers using 10 VDC analogue speed or torque commands. One PACMotion module can control up to four axes, and each module can use two of these axes for third-party servers with this upgrade. There is also support for mixing FANUC and third-party servo products that support analogue signals on the same PACMotion module.

The GE VMIVME-2128’s powerful cam function has been enhanced to further improve axis synchronisation. Cam import data allows all slave axes to be accurately positioned relative to the current position of the spindle before the machine is started, eliminating the need to lower the slave axes to synchronise with the spindle. Ensuring accurate synchronisation reduces scrap and increases throughput in the early stages of production. The new cam limited distance exit function allows the cam profile to exit the cam table in a controlled manner along the profile path at a predetermined spindle position, increasing the flexibility of the cam function. Exiting the cam before it reaches the end of the profile improves the flexibility of dynamic control in response to machine or line events such as jams or product changeovers, preventing production stoppages that can result in additional product loss.
