  • Page 88 7.4 Positioning Mode (Point Table) Positioning operation is executed simply by setting the position data, rotation speed, acceleration/deceleration time constant, etc. in the point table. (A maximum of 255-point tables can be used.) For the positioning mode (Point table) operation, refer to "LECS B2-T □ Operation Manual, section 16.4". 7.4.1 Operating Instruction of Point Table Select each point table number with DI0 ~ DI7 and start operation with ST1 or ST2.
  • Page 89 When parameter "PT01: Command mode selection" is "0000: Absolute value command method". *In positioning operation, if the command is position data (target position)≠0 and rotation speed = 0, the positioning operation command will not be accepted. In that case, clear the command remaining distance by turning MD0 (operation mode selection 1) from OFF to ON.
  • Page 90 7.5 Positioning Mode (Programimg Method) Position data, rotation speed, acceleration/deceleration time constant, etc. are created as a program, and the positioning operation is executed by executing the program. (A maximum of 256 programs with a total of 640 steps can be created.) Setup software (MR Configurator2 : LEC-MRC2*) is always required to set program data in the programming method.
  • Page 91 7.5.2 Commands in Program Method An example of program commands is shown below. For other program commands, refer to "LECSB2-T □ Operation Manual, section 16.11.2 ". The maximum number of steps in a program is 640. Up to 256 programs can be created, but the total number of steps for each program is limited to 640.

  • Page 93 7.6 Positioning Mode (Pushing Operation) Pushing operation is to generate pushing torque in the direction from "pushing start position" to "pushing limit position" within the pushing range (between "pushing start position" and "pushing limit position"). Point table method pushing operation can be selected from positioning operation or pushing operation with the auxiliary function of point table data.
