Operation command controlled by external terminal Operation command controlled by external terminal (can be monitored by communication mode) Switch 7 is ON, indicates the communication mode is enabled; switches 1 to 6 are address settings. 6 Communication There is three control modes: RS-485 communication, AC drive front panel, and external terminals. Only one mode can be used at a time and is selected by DIP Switch 6 and 7. Programming can only be done when the AC drive is in stopped mode. DIP switch settings for control DIP Switch 6 determines if control is via the AC drives front panel or external terminals. Set DIP switch 6 to OFF for AC drive front panel control and ON for external terminal control DIP Switch 7 determines if control is local or via RS-485 communication. When DIP Switch 7 is OFF, the AC drive front panel or external terminals control the drive. Note: The parameters set via RS-485 communication will remain in memory. Users can still read the status of the AC drive via RS-485 communication, but cannot send any control commands. When DIP Switch 7 is ON, the drive is controlled by RS-485 communication. Please verify the AC drive is fully stopped prior to turn DIP Switch 7 ON. If DIP Switch 7 is turned ON during operation, the error LED will illuminate. Computer Controls Each VFD-L AC Drive has a pre-assigned communication address specified by DIP Switch pins 1 to 6 (Refer to the description of setting up address). VFD-L type Communication agreement: Modbus ASCII mode, protocol <7, N, 2>, Baud rate 9600. The computer then controls each AC Drive according to its communication address. ASCII Modes: Each 8-bit data is the combination of two ASCII characters. For example, a 1-byte data: 64 Hex, shown as ‘64’ in ASCII, consists of ‘6’ (36Hex) and ‘4’ (34Hex). Character ASCII code Character ASCII code ‘0’ ‘1’ ‘2’ ‘3’ ‘4’ ‘5’ ‘6’ ‘7’ 30H 31H 32H 33H 34H 35H 36H 37H ‘8’ ‘9’ ‘A’ ‘B’ ‘C’ ‘D’ ‘E’ ‘F’ 38H 39H 41H 42H 43H 44H 45H 46H Data Format 10-bit character frame (For 7-bit character): Start bit 0 1 2 3 4 (7, N, 2) 5 6 Stop bit Stop bit 7-data bits 10-bits character frame AC Drive Addresses for RS-485 Communication VFD-L series communication addresses are 1 to 63, since 0 means broadcast to all AC drives. A DIP Switch sets to ON for equal to 1 and OFF for equal to 0. If DIP Switch 7 is OFF during power up, the communication address for the drive is 0008H, this is address 1 (factory default). If DIP Switch 7 is ON during power up, the address settings are determined by the ON/OFF positions of DIP Switches 1 to 6. Address 1 is when all switches are set to the OFF position. Switch “1” is the upper bit and switch 6 is the lower bit. (A) The addresses will remain in memory when the control mode changes to AC drive panel or external terminals. 7 (B) The addresses will remain in memory when parameters are reset. To save new addresses, remove power from the drive, set DIP switch 7 to ON and reapply power to the drive, at this time the new addresses will be read. Examples of setting up the address (Black block means ON or OFF of DIP SWITCH): ON ON 1 2 3 4 5 6 7 1 2 3 4 5 6 7 Communication Inhibits ON 1 2 3 4 5 6 7 Communication address is 01 ON 1 2 3 4 5 6 7 Communication Address is 01 ON 1 2 3 4 5 6 7 Communication Address is 02 Communication Address is 63 Communication Protocol Communication Data Frame: STX Start character ‘:’ (3AH) ADR 1 Communication address: 8-bit address consists of 2 ASCII codes ADR 0 CMD 1 Command code: 8-bit command consists of 2 ASCII codes CMD 0 DATA (n-1) Contents of data: n×8-bit data consist of 2n ASCII codes.

The following depicts the conditions that no normal response is replied to the master device. The AC drive does not receive the messages due to a communication error; thus, the AC drive has no response. The master device will eventually process a timeout condition. The AC drive receives the messages without a communication error, but cannot handle it, an exception response will return to the master device. In the exception response, the most significant bit of the original command code is set to 1, and an exception code explains the condition that caused the exception is returned. An example of exception response of command code 06H and exception code 02H: STX ‘:’ 3AH ADDRESS 1 ‘0’ 30H ADDRESS 0 ‘1’ 31H FUNCTION ‘8’ 38H (CMD) 1 FUNCTION ‘6’ 36H (CMD) 0 EXCEPTION ‘0’ 30H CODE ‘2’ 32H LRC CHK 1 ‘7’ 43H LRC CHK 0 ‘7’ 46H END 1 CR 0DH END 0 LF 0AH The explanation of exception codes: Exception codes: 01 02 03 04 09 20 Explanation Illegal command code: The command code received in the command message is not available for the AC drive. Illegal data address: The data address received in the command message is not available for the AC drive. Illegal data value: The data value received in the command message is over range for the AC drive. Slave device failure: The AC drive is unable to perform the requested action. Check Sum Error: Check if the Check Sum is correct. Watchdog Timer: The timer will reset to 0 after each valid MODBUS communication message is received. 12 Maintenance and Inspections Modern AC drives are based on solid state electronics technology, preventive maintenance is required to operate this AC drive in its optimal condition, and to ensure a long life. It is recommended to perform a monthly check up of the AC drive by a qualified technician. Before the check up, always turn off the AC Input Power to the unit. Wait at least 2 minutes after all display lamps have gone out, and then confirm that the capacitors have fully discharged. Periodic Inspection: Basic check up items to detect if there were any abnormality during the operation. 1. Whether the motors are operating as expected. 2. Whether the installation environment is abnormal. 3. Whether the cooling system is operating as expected. 4. Whether any irregular vibration or sound occurred during the operation. 5. Whether the motors are overheated during the operation. 6. Always check the input voltage of the AC drive with Voltmeter. Periodic Maintenance: It is necessary to stop the motor operation during the check up. 1. Tighten and reinforce the screws of the AC drive if necessary, cause it may loose due to the vibration or changing of temperatures. 2. Whether the conductors or insulators were corroded and damaged. 3. Check the resistance of the insulation with Megaohmeter. 4. Often check and change the capacitors and relays. 5. If use of the AC drive is discontinued for a long period of time, turn the power on at least once every two years and confirm that it still functions properly. To confirm functionality, disconnect the motor and energize the AC drive for 5 hours or more before attempting to run a motor with it. 6. Clean off any dust and dirt with a vacuum cleaner. Place special emphasis on cleaning the ventilation ports and PCBs. Always keep these areas clean, as adherence of dust and dirt can cause unforeseen failures.
