5. Route the option wiring.

Depending on the drive model, some drives may require routing the wiring through the side of the front cover to the outside to provide adequate space for the wiring. Refer to the Peripheral Devices & Options section of the drive Quick Start Guide or instruction manual for more information on wire routing of specific models. Route the wiring through the side of the front cover to the outside. In these cases, using diagonal cutting pliers, cut out the perforated openings on the left side of the drive front cover as shown in Figure 7-A. Sharp edges along the cut out should be smoothed down with a file or sand paper to prevent any damage to the wires. Route the wiring inside the enclosure as shown in Figure 7-B for drives that do not require routing through the front cover.

Note: Separate communication cables from main circuit wiring and other electrical lines.

Figure 7

A – Route wires through the openings

provided on the left side of the front cover.

Communication Cable Wiring

The dual communication cable ports on the option board act as a switch to allow for flexibility in cabling topology. For example, a traditional star network topology may be employed by using a single port on the option board. Alternatively, a daisychained approach may be employed by using both communication cable ports. This second approach reduces the requirements of MECHATROLINK-III hub module ports.

 MECHATROLINK-III Cyclic Transmissions

As a MECHATROLINK-III station, the SI-ET3 exchanges control data and I/O data with a control device, such as a controller. Communications with the master are executed by sending response data timed to the reception of command data for the local station address from the master in each transmission cycle. The formats for the command and response data follow the specifications for the MECHATROLINK Drive commands.

Phase 3 (Synchronous communications status)

Figure 11 Communication phases

 Phase 1: Initial status after power ON

Operation proceeds with a default transmission cycle of 2 ms. The transmission cycle is changed to the time indicated in the synchronous frame when a CONNECT command is received from the master. Then the phase moves to phase 2 or phase 3 after a response to the CONNECT command is returned.

Even if a transfer fault is detected in phase 1, no fault notification is provided.

 Phase 2: Asynchronous communications

All SI-ET3 commands can be used. Phase 2 starts to count the watchdog timer in the communications frame. The phase moves to phase 3 when a SYNC_SET command is received, and it moves to phase 1 when a DISCONNECT command is received.

YASKAWA ELECTRIC SIEP C730600 62B 1000-Series Option SI-ET3 Technical Manual 21

7 Transmission Interface

 Phase 3: Synchronous communications

Watchdog timer faults in the communications frame are detected. If the DISCONNECT command is received, the phase moves to phase 1. If a reception fault or a watchdog timer fault is detected, the phase moves to phase 2.

Available command is determined by communication phases. For details, refer to Ta bl e 8 and Ta bl e 9 .

 Drive-Side Error Codes

Drive-side error codes appear on the drive digital operator. Causes of the errors and corrective actions are listed in

Tab le 2 5. For additional error codes that may appear on the drive digital operator, refer to the drive Technical Manual.

 Faults

Both bUS (option communication error) and EF0 (External fault input from the option) can appear as an alarm or as a fault. When a fault occurs, the digital operator ALM LED remains lit. When an alarm occurs, the ALM LED flashes.

If communication stops while the drive is running, use the following questions as a guide to help remedy the fault:

• Is the option properly installed?

• Is the communication line properly connected to the option? Is it loose?

• Is the controller program working? Has the controller/PLC CPU stopped?

• Did a momentary power loss interrupt communications?

Table 25 Fault Display and Possible Solutions

LED Operator Display Fault Name

Option Communication Error

bUS

Cause Possible Solution

Master controller (PLC) has stopped communicating

Communication cable is not connected properly

A data error occurred due to electric interference

Option is damaged If there are no problems with the wiring and the error continues to occur, replace the option.

Connection Time-out

Duplicate Station Address

• After establishing initial communication, the connection was lost

• Only detected when the run command or frequency reference is assigned to the option (b1-01 = 3 or b1-02 = 3)

• Check that power is supplied to the PLC

• Check that PLC is not in program mode

• Check for faulty wiring

• Correct any wiring problems

• Inspect items that can minimize the effects of electrical noise

• Counteract noise in the control circuit, main circuit, and ground wiring

• If a magnetic contactor is identified as a source of noise, install a surge absorber to the

contactor coil

• Make sure the cable used meets the MECHATROLINK-III requirements

• Make sure the option ground wire is connected between option FE terminal and the drive ground terminal connected to earth ground

• The option Requested Packet Interval (RPI) timer timed out

• Make sure that RPI time is set properly

Check if the option shares Station Address with at least one other node. Check the setting values of F6-20.
