  • Page 23: Intended Audience

    !WARNING It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-mentioned appli- cations.
  • Page 24 As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system. • The PLC or outputs may remain ON or OFF due to deposits on or burning of the output relays, or destruction of the output transistors. As a counter- measure for such problems, external safety measures must be provided to ensure safety in the system.

  • Page 25: Operating Environment Precautions

    • Locations subject to possible exposure to radioactivity. • Locations close to power supplies. !Caution The operating environment of the PLC System can have a large effect on the longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PLC System.

  • Page 26: Application Precautions

    • Connecting or disconnecting the connectors !Caution Failure to abide by the following precautions could lead to faulty operation of the PLC or the system, or could damage the PLC or PLC Units. Always heed these precautions. • Install external breakers and take other safety measures against short-cir- cuiting in external wiring.
  • Page 27 Doing either of these may break the cables. • Do not place objects on top of the cables. Doing so may break the cables. • When replacing parts, be sure to confirm that the rating of a new part is correct.
  • Page 28 • If the I/O Hold Bit is turned ON, the outputs from the PLC will not be turned OFF and will maintain their previous status when the PLC is switched from RUN or MONITOR mode to PROGRAM mode.

  • Page 29: Conformance To Ec Directives

    EMC Directives OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note).
  • Page 30 Countermeasures Countermeasures are not required if the frequency of load switching for the whole system with the PLC included is less than 5 times per minute. Countermeasures are required if the frequency of load switching for the whole system with the PLC included is more than 5 times per minute.

    1-1-1 CP1L Overview The SYSMAC CP1L PLCs are the low end PLCs in the SYSMAC CP Series of package-type Programmable Controllers. They have the smallest program and I/O capacity. The CP1L PLCs are the same size as the CPM1A and CPM2A PLCs, but offer many more features and high performance.
  • Page 36 Features and Main Functions Note Settings in the PLC Setup determine whether each input point is to be used as a normal input, interrupt input, quick-response input, or high-speed counter. The instruction used to control each output point determines whether it is used as a normal output, pulse output, or PWM output.
  • Page 37 Transistor outputs, sourcing:Model numbers with “T1” before the final suffix High-speed counter inputs 4 counters/2 axes, 100 kHz (single-phase), 100 kHz for up/down pulses or pulse plus direction, 50 kHz for differential phases Pulse outputs 2 axes, 100 kHz (transistor outputs)

  • Page 38: Features

    OUTPUT instruction. The position offset is calculated using an error counter for the feedback pulse input from a rotary encoder connected to an inductive motor and the internal pulse output. The error counter is then used to output a speed command to the inverter to control positioning. This enables positioning with high-capacity motors, as well as low-cost positioning with small-capacity motors (in comparison to using a servo).
  • Page 39 Section 1-1 Features and Main Functions A virtual pulse output is created using a pulse output instruction, the position offset is calculated using an error counter, and a frequency (i.e., speed) command is output according to the position offset to control positioning.

  • Page 41 Quick-response By using quick-response inputs, built-in inputs up to a minimum input signal width of 50 µ s can be read regardless of the cycle time. The maximum num- Inputs ber of quick-response input points is 6 for CPU Units with 20, 30, or 40 I/O points and 4 for CPU Units with 14 I/O points.
  • Page 42 By adjusting the analog adjuster with a Phillips screwdriver, the value in the Analog Adjustment Auxiliary Area can be changed to any value between 0 and 255. This makes it easy to change set values such as timers and counters without Programming Devices.
  • Page 43 Up to two Serial Communications Boards each with one RS-232C port or one Serial Ports RS-422A/485 port can be added to a CPU Unit with 30 or 40 I/O points. One Serial Communications Boards can be added to a CPU Unit with 20 or 14 I/O points.
  • Page 44 ON a software switch. Modbus-RTU Inverter (2) By using the serial PLC Links, a maximum of 10 words of data per CPU Unit can be shared independently of the program among a maximum of nine CPU Units (CP1L-CP1L-CP1H/CJ1M) using RS-422A/485 Option Boards.

  • Page 45: System Configuration

    A password registration function is provided for the CPU Unit to prevent unau- thorized copy of ladder programs. If an attempt is made to read a ladder pro- gram from a CX-Programmer, access to the program is denied if the password that is entered does not match the registered password.

    Function blocks allow complex programming units to be reused easily. Once standard program sections have been created as function blocks and saved in files, they can be reused just by placing a function block in a program and set- ting the parameters for the function block's I/O. Reusing standardized function blocks reduces the time required for programming/debugging, reduces coding errors, and makes programs easier to understand.

  • Page 293: Inverter Positioning

    Error Counter positioning with an Inverter using feedback control. The PULSE OUTPUT instruction is used in the ladder program in the CP1L CPU Unit to output inter- nal pulses to a built-in error counter. The error counter calculates the position error from the number of input inter- nal pulses and the number of feedback pulses from the rotary encoder, and sends speed commands to the inverter so that the position error goes to zero.
  • Page 294 The PLC counts the feedback pulses from the encoder using a high-speed counter. When a deceleration point is reached, the speed is changed to con- trol the stop position. If the precision of the stop position must be increased, the stop position must also be detected to control positioning.
  • Page 295 (1) The CP1L’s inverter positioning function is designed to increase position- ing speed and stopping precision by reading position information and us- ing a feedback loop with an error counter to switch speeds. It does not increase the response, stopping precision, or speed change rate of the inverter and motor.

  • Page 296: System Configuration

    Note (1) The inverter positioning function uses either serial communications or an analog output, and is thus possible with a CP1L CPU Unit with either tran- sistor or relay outputs. (2) The inverter positioning function does not use external pulse outputs.

  • Page 297: Functional Overview

    Although normally the pulse output instructions are used to output pulses from CP1L output contacts, when inverter position- ing 0 or inverter positioning 1 is enabled in the PLC Setup, the internal po- sition error counter (called simply the “error counter”) is enabled and the pulse output instruction will output internal pulses to the error counter.
  • Page 298 Section 5-3 Inverter Positioning 7. When a speed command is sent to the inverter, the motor will turn at the command speed and feedback pulses (i.e., the amount of movement) from the encoder will be returned to a high-speed counter of the CP1L. The CP1L will continue to send a speed command to the inverter until the error counter (i.e., the position error) goes to zero, i.e., until positioning has been...
