Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.
Drive disable occurs when input contacts CCWL & CWL are operated simultaneously. The manual's first action is: “1. Remove input contact signal CCWL or CWL. 2. Check all input wiring for correct connections.”
CPU Error indicates a control system malfunction. The manual's first action is: “Turn off the power. Turn on again after 30 min. If error alarm still exists, this may be due to external interference. Refer to the chap…
Motor's speed is 1.5 times more than motor's rated speed. The manual's first action is: “1. Reduce the speed command. 2. Electronic gear ratio is incorrect check and set correctly. 3. Adjust speed loop gains (Sn211 & …
The deviation between Pulse command and encoder feedback is greater than the setting of Pn308 or Pn309. The manual's first action is: “1. Increase the position loop gain (Pn310 and Pn311) setting value. 2. Increase in…
Motor over-current occurs when current exceeds four times rated current. The manual's first action is: “1. Check if the motor wiring U,V,W)and encoder wiring correct or not. 2. Internal interference and mal-function .…
Emergency Stop is activated when the input contact point EMC is triggered. The manual's first action is: “1. Disable Emergency stop signal input. 2. Internal mal-function. Ensure that all connection are correct, refer…
The drive has encountered a memory error due to a parameter write-in error. The manual's first action is: “Disconnect all command cable then re-cycle the power. If alarm still occurs, it means the Drive was failure.”
Multi-function contact setting error occurred due to input/output contacts function settings being incorrect. The manual's first action is: “1. Check parameters Hn501~Hn506 trigger level selected by 2nd digit of Hn 50…
The system is operating normally. The manual lists no action for this code.
ASCII CHECK FAILURE indicates a communication error or timeout in data transmission. The manual's first action is: “1. Check parameter setting of communication function. 2. Check wire connection between drive and cont…
RTU CHECK FAILURE indicates a CRC check error or encoder failure/connection problem The manual's first action is: “1. Check the motor's encoder connections. 2. Check the encoder if short circuit, poor solder joints or…
A slave device has failed due to an unrecoverable error or circuit overload. The manual's first action is: “1. Check connection of the motor cable (U,V,W) and encoder. Check power cable connection. Refer to the diagra…
The drive has detected an illegal data value or exceeded its rated load during continuous operation. The manual's first action is: “1. Check connection for Motor terminal s (U,V,W) and Encoder. 2. Adjust the Drive gai…
The data address received in the query is not an allowable address for the server (or slave). The manual's first action is: “1. Use multi-meter to check whether the input voltage is within the specified limit. 2. Chec…
The drive received an illegal function command or the input voltage is below 190Vac. The manual's first action is: “Use multi-meter to check whether the input voltage is within the specified limit. If it can not be so…
