!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 25 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 26: 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 27: 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 28 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 29 • 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 68: Function Blocks
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.

• Refreshing between I/O words in the CIO Area and CPU Unit built-in I/O, CP/CPM1A-series Expansion Units, and CP/CPM1A-series Expansion I/O Units All I/O refreshing is performed in the same cycle (i.e., time slicing is not used). I/O refreshing is always performed after program execution. Units Max.
Page 117 Immediate Refreshing When the immediate refreshing variation of an instruction is specified and the instruction’s operand is an input bit or word in the Built-in I/O Area, the word containing the bit or the word itself will be refreshed.

Page 118: Initialization At Startup
Note IORF(097) has a relatively long execution time which increases with the num- ber of words being refreshed. Be sure to consider the affect of this time on the overall cycle time. Refer to the CP Series Programmable Controllers Program- ming Manual for instruction execution times.

Holding time for 5 V internal power supply after power OFF detection: The maximum time that the 5 V internal power supply voltage will be maintained after the power OFF condition is detected.
Page 123: Computing The Cycle Time
Section 2-7 Computing the Cycle Time 2-7-1 CPU Unit Operation Flowchart The CPU Unit processes data in repeating cycles from the overseeing pro- cessing up to peripheral servicing as shown in the following diagram. Power ON Checks Unit connection status.
Page 124: Cycle Time Overview
• Fixed peripheral servicing time in the PLC Setup Note 1. The cycle time is not affected by the number of tasks that are used in the user program. The tasks that affect the cycle time are those cyclic tasks that are READY in the cycle.
Page 125: Minimum Cycle Time

Page 128: Online Editing Cycle Time Extension
Be sure that the additional time will not adversely affect system operation. Note When there is one task, online editing is processed all in the cycle time follow- ing the cycle in which online editing is executed (written). When there are mul- tiple tasks (cyclic tasks and interrupt tasks), online editing is separated, so that for n tasks, processing is executed over n to n ×2 cycles max.
Page 129: I/O Response Time
The I/O response time is the time it takes from when an input turns ON, the data is recognized by the CPU Unit, and the user program is executed, up to the time for the result to be output to an output terminal. The length of the I/O response time depends on the following conditions.
Page 130: Interrupt Response Times
20 ms Minimum I/O response time = 1 ms + 20 ms + 0.1 ms = 21.1 ms Maximum I/O response time = 1 ms + (20 ms × 2) + 0.1 ms = 41.1 ms Input Response Input response times can be set in the PLC Setup. Increasing the response Times time reduces the effects of chattering and noise.
Page 131: Serial Plc Link Response Performance
1 ms max. There is also an error of 80 µs in the time to the first scheduled interrupt (0.5 ms min.). Note Scheduled interrupt tasks can be executed during execution of the user pro- gram (even while an instruction is being executed by stopping the execution of an instruction), I/O refresh, peripheral servicing, or overseeing.

For restrictions on the number of Expansion Units and Expansion I/O Units that can be connected, refer to 1-2 System Configuration .
Page 138 Wiring Ducts Whenever possible, route I/O wiring through wiring ducts. Install the duct so that it is easy to wire from the I/O Units through the duct. It is handy to have the duct at the same height as the PLC.
Page 139 Section 3-3 Routing Wiring Ducts Install the wiring ducts at least 20 mm between the tops of the PLC and any other objects, (e.g., ceiling, wiring ducts, structural supports, devices, etc.) to provide enough space for air circulation and replacement of Units.

Index Registers Section 4-11 (2) If two-word data is accessed from the last address in the DM Area (D9999 for the CP1L-L@D@-@ and D32767 for other CPU Units), the Access Er- ror Flag (P_AER) will turn ON and the data at D9999 or D32767 will not be read or written.
Page 196 ,– –IR@ Example This example shows how to store the PLC memory address of a word (CIO 2) in an Index Register (IR0), use the Index Register in an instruction, and use the auto-increment variation. MOVR(560) Stores the PLC memory address of CIO 2 in IR0.
Page 197 ,IR2 +5 , IR2 When the operand is treated as a bit, the leftmost 7 digits of the Index Reg- ister specify the word address and the rightmost digit specifies the bit num- ber. In this example, MOVR(560) sets the PLC memory address of CIO 13 (0C00D hex) in IR2.
Page 198: 4-11-1 Using Index Registers
The SRCH(181), MAX(182), and MIN(183) instructions can output the PLC memory address of the word with the desired value (search value, maximum, or minimum) to IR0. In this case, IR0 can be used in later instructions to access the contents of that word.
Page 199 If, for example, instruction A above is a comparison instruction, table data could be read from start to the end of the table to compare all of the data with a specific value. In this way, blocks of user-defined processing can be freely created depending by applying Index Registers.
Page 200: 4-11-2 Precautions For Using Index Registers
Each Index Register task is processed independently, so they do not affect each other. For example, IR0 used in Task 1 and IR0 used in Task 2 are differ- ent. Consequently, each Index Register task has 16 Index Registers.
Page 201 FINS commands, write a program to store Index Register values from each task to another area (e.g., DM area) at the end of each task, and to read Index Register values from the storage words (e.g., DM area) at the beginning of each task.

Page 314: 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 315 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 316 (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 317: 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 318: 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 319: Other Functions
Inverter Positioning Section 5-3 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...
Page 320: Specifications
An inductive motor driven with an inverter is different from a servomotor in that Using Minimum Output the torque at low speeds is so low that it may not be possible to turn the motor Setting shaft at the minimum frequency. The CP1L provide a minimum output setting the ensure a minimum output to enable positioning at low speeds even when there are extremely few pulses in the error counter.
Page 321 If inverter positioning 1 is used, pulse output 1 and PWM1 cannot be used. (2) If inverter positioning 1 is used with a CPU Unit with 14 I/O Points, origin searches cannot be used. (3) If the continuous output mode is specified (i.e., if the number of pulses is not specified), be sure to use the high-speed counter (linear mode) so that it does not overflow.

The normal pulse output instructions are used (PLS2, PULS + SPED, or PULS + ACC). One of the inverter positioning ports is specified as the port for the instruction. Just like pulses are output externally for the normal pulse out- put instructions, error counter pulses are accumulated in the internal error counter when executing inverter positioning.
