VFD-L Series CRC (Cyclical Redundancy Check) is calculated by the following steps: Step 1: Load a 16-bit register (called CRC register) with FFFFH. Step 2: Exclusive OR the first 8-bit byte of the command message with the low order byte of the 16-bit CRC register, putting the result in the CRC register. Step 3: Shift the CRC register one bit to the right with MSB zero filling. Extract and examine the LSB.

VFD-L Series 3.6 Exception response: Except for broadcast messages, the AC drive is been expected to return a normal response after receiving command messages from the master device. 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.
VFD-L Series Error message 1 2 3 4 5 Meaning 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 not available for the AC drive. Slave device failure: The AC drive is unable to perform the requested action.

VFD-L Series CHAPTER 6 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. 6.
VFD-L Series CHAPTER 7 Troubleshooting and Fault Information The VFD-L AC drive has a comprehensive fault diagnostic system that includes several different alarms and fault messages. Once a fault is detected, the corresponding protective functions will be activated. The following faults are displayed on the AC drive digital keypad. The six most recent faults can be read on the digital keypad display by viewing Pr.6-07 to Pr.6-12. NOTE: Faults can be cleared by a reset from the keypad or Input Terminal.
VFD-L Series Fault Name Fault Descriptions The AC drive temperature sensor detects excessive heat. The AC drive detects that the DC bus voltage has fallen below its minimum value. The AC drive detects excessive drive output current. Corrective Actions 1. Ensure that the ambient temperature falls within the specified temperature range. 2. Make sure that the ventilation holes are not obstructed. 3. Remove any foreign objects on the heatsinks and check for possible dirty heat sink fins. 4.
VFD-L Series Fault Name Fault Descriptions Over-current during acceleration: 1. Short-circuit at motor output. 2. Torque boost too high. 3. Acceleration time too short. 4. AC drive output capacity is too small. Over-current during deceleration: 1. Short-circuit at motor output. 2. Deceleration time too short. 3. AC drive output capacity is too small. Over-current during steady state operation: Corrective Actions 1. Check for possible poor insulation at the output line. 2.
