PURPOSE:To attain the operation without knowing the meaning of printed symbols on a panel by printing out the most common schematic diagram or a graphic for an external interlocking device of a preset counter onto the print panel while being related to step symbols. CONSTITUTION:A speed versus time patten and a step symbol on a panel are related by an indicating line, that is, the step symbol and its corresponding time points t1-t6. The point t1 is a point of time when a counter 2 starts programming while receiving a program designation signal P and a start signal S from a sequencer 1 and a data is set by a function key. The counter 2 gives a start/stop command E to an inverter 3 and a motor 4 is started at the point of time t2. The point of time t3 is a point of time when an origin signal Z is inputted to the counter 2 via a limit switch LS-Z. The point of time t4 is a point of time when the counter 2 outputs a low speed command L to the inverter 3, and the point of time t5 is a point of time when a carrier reaches an object point and the motor 4 is stopped. The point of time t6 is a time of the program end signal output.
