(2) General installation steps (taking method A as an example, differences in other methods have been marked)

Power off and discharge: Disconnect all power sources from the drive, wait for the internal capacitor to discharge (at least 5 minutes until the CHARGE indicator light on the drive goes out), confirm that there is no dangerous voltage, and then remove the digital operator (F), front cover (E), and terminal cover (G). The removal steps should refer to the manual provided with the drive;

Option fixing: Use the M3 screw inside the package to fix the option in the designated position of the driver (refer to Figure 4 in the document for the position), ensuring that it is firmly fixed and not loose;

Cable connection: Pull out the loose end of the reserved connection cable for the driver, insert it into the CN1 interface of the option, pay attention to the interface direction, and reverse insertion may damage the connector or driver;

Cover plate reset: Reinstall the driver front cover, terminal cover, and digital operator to ensure that the cables are not squeezed by the cover plate and to avoid insulation layer damage causing short circuits;

External power supply wiring: Go to the "Wire the Option" section on page 40 of the document and connect an external 24V power supply to the option terminal block TB1 (terminal definition: 24=+24VDC input, 0=0V, FE=ground). The wiring steps are as follows:

Loosen the TB1 terminal screw with a straight screwdriver;

Peel off the insulation layer of the cable (with a bare length of about 5.5mm, to avoid the wire ends from unraveling);

Insert the cable into the corresponding terminal and tighten the screw (torque 0.22-0.25N · m);

Wrap the cable shielding layer with heat shrink tubing or electrical tape to avoid short circuits caused by contact with other circuits 🔶 2-393;

(3) Special installation requirements (for C-F method)

Fixed difference: The C-F method requires the installation of screws (tighten with a 6mm wrench, torque 0.5-0.7N · m) first, and then fix the option with screws;

Cable differences: C method uses connection cable A, D/F method uses connection cable B, E method uses connection cable C, and the cables need to be sorted according to the document diagram (such as Figure 23, 27) and fixed with zip ties to avoid cable entanglement or compression.

3. Key wiring specifications

Power requirements: The external 24V power supply must be UL Listed Class 2 certified (or equivalent) to avoid the risk of electric shock or fire caused by the use of non certified power supplies. The power supply must be able to provide at least 3A current (the instantaneous current when the option is powered on is twice the conventional value, lasting for about 0.5 seconds);

Cable specifications: Shielded twisted pair cables are required for control cables, with a recommended wire diameter of 0.75mm ² (18AWG). The suitable wire diameter range for single strand cables is 0.25-1.5mm ² (24-16AWG), and the suitable wire diameter for crimping terminals is 0.25-0.5mm ² (24-20AWG);

Shielding treatment: The cable shielding layer needs to be grounded at one end (connected to the driver grounding terminal) to avoid circulating current caused by double ended grounding, and the grounding area should be as large as possible (refer to Figure 40 in the document);

Operation verification and troubleshooting

1. Run verification steps

After installation and wiring are completed, the following steps should be taken to verify whether the option functions properly:

Power on the main circuit of the driver and confirm that the external 24V power supply has been connected to the TB1 terminal of the option, and that the option is properly connected to the driver cable;

Disconnect the power supply of the main circuit of the drive, and the option should supply power to the control circuit of the drive;

Observe the red LED indicator light on the option. If it lights up, it indicates that the option is working properly;

When checking the digital operator of the drive, it should briefly display "Fdv" or "AUv" (undervoltage prompt) for about 10 seconds. This prompt is a normal phenomenon, indicating that the control circuit has been powered through the option 🔶 2-413;

2. Handling of abnormal situations

If the option LED does not light up: check if the external 24V power supply is normal (voltage range 19.2-28.8V), if the TB1 terminal wiring is loose or reversed, and if the option is in good contact with the driver cable;

If there is no "Fdv/AUv" prompt on the operator: first confirm that the wiring is correct, then check if the driver parameter o2-19 is set correctly. If it is still abnormal, it may be a problem with the option or driver, and contact Yaskawa after-sales service;

In addition, Table 3 (Power Supply and Control Circuit) of the document specifies the operation of the control circuit and driver under different power states, which can be used to assist in fault diagnosis:

Driver main circuit power options, power supply status, driver control circuit operation status, driver operation possibility

ON, ON, can run normally

ON/OFF can run

OFF/ON can access data (parameters/faults) but cannot run

OFF: Stop running and cannot run

Core Security Standards

(1) Electrical safety

Prohibited live operation: During installation, wiring, and maintenance, all power sources must be disconnected and the capacitor must be discharged (at least 5 minutes). The CHARGE light must be turned off before operation, otherwise it may cause electric shock death or serious injury 🔶 2-133;

Authorization operation requirements: Only authorized personnel who have received training are allowed to install and maintain. Unauthorized personnel operation may cause safety accidents;

Prohibited from modifying equipment: It is not allowed to modify the driver body or option circuit without authorization. Modifying will result in the expiration of the warranty, and Yaskawa will not be responsible for any damage caused by this;

(2) Fire prevention and equipment protection

Terminal torque requirements: All terminal screws must be tightened to the specified torque (such as TB1 terminal 0.22-0.25N · m, screw 0.5-0.7N · m). Too loose may cause poor contact, heat generation, and fire, while too tight may damage the terminals 🔶 2-149;

Static electricity protection: When in contact with options, drivers, or circuit boards, it is necessary to follow the ESD (electrostatic discharge) protection process (such as wearing an anti-static wristband) to avoid static electricity damaging the circuit;

Environmental restrictions: It is prohibited to expose options or drivers to halogen disinfectants, and they should not be stored in fumigated wooden packaging to avoid chemical damage to electrical components
