TOSHIBA TE2 series low-voltage digital solid-state soft starter

2. Programming operation process

Enter programming mode: In the status display mode (default display of A-phase current), press the 【 Fn 】 key to enter the F001 parameter interface.

Adjust parameters:

Press the ←/→ key to select the digit to be modified (flashing);

Press the 【 ↑/↓ 】 keys to adjust the value (long press for 2 seconds to start automatic stepping);

Press the 【 ENT 】 key to save and display 'End' for confirmation.

Password protection:

Set F070 to a non-zero value (1-999) to enable the password, and enter the password for the next modification;

If you forget your password, please contact Toshiba customer service to restore the factory settings (F071=2) without clearing the password.

Communication programming: Connect PLC/upper computer through RS485 Modbus and modify parameter registers (such as register address 0x0001 corresponding to F001).

Startup and troubleshooting

1. Initiation process and inspection

Step operation content Key checkpoints

1. Confirm that the wiring of the main power supply, motor, and control power supply is correct, the grounding is reliable, and there is no looseness

The required parameters F001 (FLA), F002 (SF), and F010 (slope type) for parameter settings have been correctly configured

3. Power on test: Connect the control power supply, the "Power On" LED lights up and displays 【 0000. 】 (phase A has no current)

Press the Start button to start the test, the motor accelerates according to the set slope, the "At Speed" LED lights up (the motor reaches full speed), and the bypass contactor is closed

5. If the machine stops during startup, check the fault code (such as "oLA"=overload, increase F003)

2. Common faults and troubleshooting

Troubleshooting steps for fault codes and causes

NFLA motor FLA not set (F001=0) 1. Enter programming mode; 2. Let F001 be the motor nameplate FLA; 3. Restart after saving

1. Check if the main power supply L1/L2/L3 is out of phase during PLc operation; 2. Check if the motor wiring T1/T2/T3 is loose; 3. Confirm that the phase loss protection (F101) has not been mistakenly enabled

Overload during oLA startup: 1. Check if F003 (startup overload level) is too small (if set to Class 5), it can be increased to Class 15; 2. Check if the load is too heavy, reduce the starting load or increase the current limit (F014)

SSd SCR short circuit or no load 1. Disconnect the power supply and measure whether the SCR (L1-T1, L2-T2, L3-T3) is short circuited; 2. Confirm that the motor is connected (no load will report this fault)

Ground fault during GFc operation: 1. Check if the motor winding is grounded; 2. Check if the cable insulation is damaged; 3. Adjust the grounding fault threshold (F046) or delay (F047)

3. Fault recording and reset

Fault record: F085-F093 stores the last 3 faults, including fault codes (F085/F088/F091), timestamps (F086/F089/F092), and date stamps (F087/F090/F093).

Reset method:

Manual reset: After troubleshooting, press the [Reset] button. If there is an overload fault, wait for the motor to cool down (heat capacity H ≥ F059);

Automatic reset: F052 selects the fault type (such as 4=phase loss), F053 sets the reset frequency (1-10 times), 1 minute/time;

Remote reset: Disconnect the control power and reconnect it (applicable to scenarios without Reset button).

Maintenance and Appendix

1. Regular maintenance

Maintenance project cycle operation requirements

Clean the heat sink every 3 months (in dusty environments) and blow it with 80-100psi dry compressed air. Do not use chemicals/metal brushes

Check the power/control terminals for looseness every 6 months and tighten them again (according to torque requirements)

Fan inspection: Every year, listen to the running noise of the fan. If there is any abnormality, replace it (with a lifespan of 3 years/30000 hours)

Capacitor inspection: The main circuit capacitor has a lifespan of 10 years/73000h every 5 years. If it exceeds the lifespan, it is recommended to replace it

Backup parameters every year through BSD Configurator to avoid loss

2. Important Appendix Content

Appendix 1 (Slope Details): Detailed explanation of the differences in VR/CR slope curves. It is recommended to use VR for centrifugal pumps and CR for long conveyor belts.

Appendix 2 (Pump Flex Deceleration): Used for soft stop of pumps to avoid water hammer effect, it is necessary to set the starting deceleration voltage (F025), stopping voltage (F026), and deceleration time (F027).

Appendix 3 (Password Protection): The process for handling lost passwords requires contacting Toshiba customer service for unlocking methods.

Appendix 4 (External Overload): When multiple motors are controlled or started by bypass, an external overload relay (OLR) is required. The wiring example is shown in document APP4.2.

Appendix 5 (Parameter Record): A blank table is used to record the parameters modified by the user for easy maintenance and traceability.
