This manual provides information for programming and operating the Unit. Be sure to read this manual before attempting to use the Unit and keep this man- ual close at hand for reference during operation.
Page 25: Operating Environment Precautions
As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system. • The PLC or PCU outputs may remain ON or OFF due to deposits on or burning of the output relays, or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.
Page 26: Application Precautions
Always heed these precautions. Failure to abide by the following precautions could lead to serious or possibly fatal injury. • Always connect to a ground of 100 Ω or less when installing the Units. Not connecting to a ground of 100 Ω or less may result in electric shock.
Page 27 • Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may break the cables. • Do not place objects on top of the cables or other wiring lines. Doing so may break the cables.
Page 28: 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 234: Servo Status Flags
Axis Operating Input Memory Areas 4-8-4 Servo Status Flags The Servo Status Flags (word b+1) are flags that monitor the control status of the Servo Drive. This enables monitoring of the Servo Drive control status (position, speed, torque control loop).
Page 235 This flag turns ON when the SERVO LOCK Bit (a+1, bit 00) in the Axis Oper- ating Output Memory Area turns ON, and turns OFF when the SERVO UNLOCK Bit (a+1, bit 01) turns ON or an error that sets the Servo in free run state occurs.
Page 236 This flag turns ON when the command position reaches the target (stop) position (Sending position control command to Servo Drive completed), and the feedback position is within the range set for the target (stop) posi- tion Servo Parameter Positioning Completion Range 1 (Pn431 for R88D- KN@, Pn060 for R88D-GN@, Pn500 for R88D-WT@, and Pn522 for R88D- WN@-ML2 and SMARTSTEP Junior).
Page 237 Zero Speed Flag (during Speed Control) Word Function The function of these flags depends on whether position control or speed con- trol is being used.

An output area of 25 words and an input area of 25 words are allocated to each axis according to the axis number registered in the scan list.

Page 272 The actual communi- cations cycle (data refresh cycle) is a time cycle that is a multiple of the trans- fer cycle's set value. The set value for the communications cycle is determined by the number of connected MECHATROLINK devices and depends on the PCU communications processing.

When a connection is released, the active axis is put in the Servo free run state. For all axes registered in the scan list, the status that is input in the Axis Oper- ating Input Memory Areas for each axis becomes the initial status (non-exe- cuting status), except for the Error Flag and axis error code.

Page 281 ■ PCUs with Unit Version 1.3 or Later Axis operation is possible for axes that are registered in the scan list and for which MECHATROLINK communications was started (i.e., axes for which Axis Communications Status Flags are ON), regardless of whether an alarm is present in the Servo Drive or whether the connected axes match the scan list.
Page 282: Mechatrolink Communications Errors
In this example, the axes for which MECHATROLINK communications can actually be started are 1, 3, and 4. This does not match the axes registered in the scan list (i.e., axes 1 to 5), so an MLK initialization error (unit error code 0020 hex) occurs.

After the cause of the error is removed, the axis error is cleared by turning ON the ERROR RESET Bit in the Axis Operating Output Memory Area. When clearing the axis error, make sure that the ERROR RESET Bit will remain ON until the Busy Flag for the corresponding axis turns ON.
Page 286: Rejoining The Connection
This function can be used only with Position Control Units with unit version 2.0 or later. If any axis registered in the scan list is in either of the following conditions, the error cannot be cleared with the normal error reset procedure and axis opera- tions will not be possible from the Position Control Unit.
Page 287 TROLINK communications is performed in the same way as when a connec- tion is established. This can be used to restart communications for any axes registered in the scan list that are not part of the connection or for which axis operations are not possible due to a communications error.
Page 288 When executing processing for an axis to rejoin a connection, the Unit Busy Flag will turn ON for a minimum of one scan time and until the Axis Communi- cations Status Flags turn ON for the axes being processed or until a MLK ini- tialization error (Unit error code: 0020 (hex)) occurs after the REJOIN command bit is turned ON.

Overview The parameters set in the PCU (Common Parameters and Axis Parameters) can be transferred to and from the CPU Unit's EM Area using the READ DATA Bit and WRITE DATA Bit. Also, the parameters that have been written to the PCU can be saved to the PCU's internal flash memory using the SAVE DATA Bit.

These components may deteriorate faster, however, due to factors such as the operating environment. Therefore, routine inspection is required. The standard inspection schedule is once every six months to one year. More frequent inspections may be advisable depending on the operating environ- ment.

13-3 Handling Precautions • Turn OFF the power before replacing the PCU. • If a PCU is found to be faulty and is replaced, also check the new PCU to make sure that there are no errors. • When returning a faulty PCU for repair, make a detailed record of the PCU's malfunction and take it together with the PCU to your nearest OMRON office or sales representative.

Page 660 Flag This bit is used as a Warning Flag. Error Flag The function of this bit is the same for errors that occur in individual axes. The error flags for Unit common errors are allocated as Unit Error Flags in the Common Operating Memory Area.
Page 661 The origin input status is provided either in bit 05 of this word (b+3) when phase Z input signal is set or in bits 06 to 08 of this word when the external latch signal is set, according to the selected signal.
Page 662 Operating Data Area words for CS1W/CJ1W-NC113/133/213/233/413/433 PCUs are shown in the following table for the X axis of the CS1W/CJ1W-NC113 PCU. The beginning word “I” is allocated in either the Special I/O Unit Area or a user-specified DM/EM Area using settings in the Common Parameters.

CS1W/CJ1W-NC113/133/213/233/413/433 The time from the initial speed until the maximum speed is reached is set in the following axis parameters. Origin search acceleration time (ms) Origin search deceleration time (ms)

Page 665 The setting unit for the Zero Point Return Approach Speed 1 parameter is 100 command units/s. Therefore, to set the command unit to pulses, the set value for earlier PCUs must be multiplied by 1/100 to obtain the set value required for CS1W/CJ1W-NC271/471/F71 PCUs.
Page 666 Origin Established and No Origin Status The No Origin Flag in both earlier PCUs and the CS1W/CJ1W-NC271/471/F71 indicates whether the origin has been established or not. The differences in the conditions whereby the No Origin Flag turns ON or OFF are as follows:...
Page 667 Acceleration time (ms) Deceleration time (ms) For each parameter, the data that has been set in the Operating Data Area is enabled when the direct opera- tion (ABSOLUTE MOVEMENT or RELATIVE MOVEMENT) is started. CS1W/CJ1W-NC271/471/F71 The rate of increase or decrease in speed within a specified time unit is set in the following Servo Parameters.
Page 668 Pn80F (deceleration constant switching speed) = 0 Changing Target Position and Changing Target Speed The target position and target speed can be changed during axis operation in the same way for both earlier PCUs and the CS1W/CJ1W-NC271/471/F71 PCU by using the following operation.
Page 669 Data Transfer In earlier PCUs, all the parameters set by the PCU are in the Unit, and data is transferred using the PCU's data transfer functions (data transfer bit or IOWR instruction). In CS1W/CJ1W-NC271/471/F71 PCUs, however, data is classified into three types: Common Parameters, Axis Parameters, and Servo Parameters.
