Designed for motion-based machine builders and industrial OEMs, the new
modules can be used with any controller from the Rexroth line. The new I/O modules include the SSI and INC IN modules, which provide
powerful encoder feedback capabilities for even the smaller, less
expensive PLCs, such as Rexroth’s L10. The SSI and INC can handle a
large number of axes and can dictate position and speed. The SSI
features four inputs and position detection which can identify the
motor position during its rotation. The INC encoder pulses
quickly as the axis rotates. Based on a combination of signals that
comes from the drives, the encoder module can identify the position of
the motor in its rotation. The PWM/2 module provides pulse width modulation and step and
direction control, giving machine builders more flexibility to alter
the width of the pulse. This can be used to reduce the temperature of
the drive and the amount of energy consumed. The step and direction aspect also allows the module to be used
with stepper drives and motors.
