Abstract
Apparatus for controlling a reciprocating movement of a reciprocating member over a predetermined operating stroke by forward and reverse rotations of a drive motor. The apparatus includes an encoder for generating pulses each corresponding to an incremental distance of movement of the reciprocating member, and an operator's control panel having a plurality of operator's control switches for entering data and commands for controlling the drive motor, and a data display normally placed in a display mode for displaying information, a motor controller for controlling the drive motor according to the entered data and the encoder pulses. A detector is provided for detecting a specific command generated by the control switch or switches. The display is controlled by a display controller such that upon detection of the specific command by the detector, the display is placed in an inspection mode for providing an indication as to whether the encoder pulses are present or not.
