Troubleshooting and Maintenance
This section describes SJ100DN Series error codes corresponding to Chapter 6,
"Troubleshooting and Maintenance," in the SJ100 Inverter Instruction Manual.
Error Codes and Notes
SJ100DN Series inverters have the additional error code listed below.
Error
Code
E 6 0
A DeviceNet communication error will result in an inverter trip with error code 60, as
well as other actions that you can specify. The table below lists the DeviceNet fault types
detected and the inverter actions.
DeviceNet Error Type
Bus-OFF detection *1
DeviceNet watchdog timer time-out
(time period in P_44 setting) *3
DeviceNet connection time-out *4
Connection released *5

Communication error
The inverter does not support DeviceNet requests during a communication
fault. To clear a Bus-OFF error, power cycle the inverter or reset it via [RS].
The P_45 setting only applies to the inverter's DeviceNet watchdog timer
time-out, not a connection time-out or a host connection release event.
The inverter's DeviceNet watchdog timer is active whenever the inverter is in
Run Mode and its DeviceNet connection is enabled. (The DeviceNet connec-
tion may be enabled either by P_43 = 1 or when the signal is ON at the intelli-
gent input terminal [DNT], if assigned. [DNT] input has priority over P_43.)
The DeviceNet connection time-out refers to the time-out within the
DeviceNet Connection Object, per the DeviceNet specifications. In if Run
Mode when the time-out occurs, the inverter decelerates the motor to a stop.
The host computer can release the connection to the inverter via the standard
service release mechanism. In if Run Mode when the time-out occurs, the
inverter decelerates the motor to a stop.
Cause(s)
•
The DeviceNet cable may be disconnected or have
an open wire, short, etc.
•
The communication error may be due to the
external device. Check whether the interruption is
for more than 3 seconds before resetting the error.
If so, the watchdog timer in the inverter is timing
out due to no response from the external device.
Inverter Action
P_45 setting (*2), five options:
00 .. Trip
01 .. Decelerate and trip
02 .. Hold last speed
03 .. Free-run stop
04 .. Decelerate and stop
(same as above)
Decelerate and trip
