6 Troubleshooting
The following table describes the faults that may occur during the use of the MD500-
EN1 card and the AC drive.
Table 6-1
Fault causes and solutions
Symptom Possible Cause Solution
Communication
failure between the
MD500-EN1 card and
AC drive
1. Ethernet/IP
communication is not
supported by AC drive.
2. The communication
con󶍾guration of the
MD500-EN1 card is
incorrect.
3. The MD500-ECAT card is
faulty.
1. Check whether Ethernet/IP
communication is supported by the
AC drive.
2. Correctly con󶍾gure communication
parameters of MD500-EN1 card.
3. Replace the MD500-EN1 card.
Err16
(communication
error) reported by
the AC drive during
running
1. The communication
data is abnormal.
2. The network cable is
damaged or connected
incorrectly.
3. The AC drive su󶍽ers
external interference.
1. Check whether Ethernet/IP master
program is normal.
2. Check whether the network cable
is connected correctly. Replace the
network cable if required.
3. Use the Cat5e shielded twisted
pair (STP) network cable as required.
Check that the MD500-EN1 card is
grounded correctly. Eliminate the
external interference. Contact the
agent or Inovance for technical
support if necessary.
Fault code is 8-bit binary integer. Every bit represents a speci󶍾c fault. Fault codes can
be obtained through converting parameter values into 8-bit binary values. For example,
the read value 3 of FD-58 is converted to binary value 0000 0011, then the fault codes
are Bit0 and Bit1. The following table lists the fault description and solutions.
Note: Multiple faults may be present when a fault code appears.
Fault
Code
Description Solution
Bit 7 N/A N/A
Bit 6
Communication with AC drive
failed or AC drive version
incorrect
Upgrade the AC drive software to the version
that supports EIP.
Bit 5 I/O Messages mapping Error Check PLC con󶍾guration.
Bit 4 Timeout
Check whether the circuit and master station
operation is normal.
