Expands servo control
February 4th 2008

Offering control for servo and stepper motor axes, together with onboard I/O and fieldbus connectivity, the new NextMove-ESB2 from Baldor expands servo control capability from three to four axes. Combined with control for 4 stepper motor axes, and I/O for material handling and general machine control functions, the NextMove-ESB2 module offers an economic standalone solution that can be used for a wide range of machinery applications.

Based on an advanced DSP core, NextMove-ESB2 delivers real-time performance. It supports servo loop closure times of 100 microseconds on the four main axes, with six-term closed loop control for accurate positioning (PID, velocity, acceleration feed forward, and velocity feedback).

Flexibility of control is aided by a further free encoder input which may be used as a 'master' axis. Depending on the drives chosen, the module's stepper outputs may also be used for servo motor control, making the module capable of controlling up to eight precision servo motor axes. NextMove-ESB2's four stepper axes provide pulse and direction outputs at up to 500 kHz.
