Protective Functions
7-18
Error No.
Protective function Causes Measures
Main Sub
69 0 Inter-modules
communication timeout
error protection

The power supply module detected a
disconnection of Inter-modules
communication or an error in received
data.
→Err69.0 occurs in all driver modules
connected to the power supply module.

The driver module detected a
disconnection of Inter-modules
communication or an error in received
data.
→Err69.0 occurs in the driver module that
detected the error.

Check that the power supply module
communication cable is connected
properly.

Check that the DIP switches for power
supply module communication ID setup
on the front panel of the driver module is
set correctly.

Take measures against noise, such as
properly grounding the power supply
module and driver module, inserting a
noise filter or surge absorber in the power
supply line, and installing a signal noise
filter on each cable, input/output line, and
power line connected to the driver module.

Replace the driver module.

Replace the power supply module.
1 Inter-modules
communication CRC
error protection

With the power supply module,
Inter-modules communication could be
received, but CRC error was detected.
→Err69.1 occurs in all the driver modules
connected to the power supply module.

In the driver module, Inter-modules
communication could be received, but
CRC check did not match.
→Err69.1 occurs on the driver module that
detected the error.
2 Power supply module
error protection 1 An error that does not need to be handled
with immediate stop was detected in the
power supply module. (Main power supply
overvoltage, main power supply phase lack,
regeneration error, etc.)
→Err69.2 occurs in all driver modules
connected to the power supply module.

Check the detail information on power
supply failure on PANATERM for Multi,
and remove the cause of the error
referring to "11.5 Protective functions" /
warning action of the power supply
module and turn on the control power
supply again.

Replace the power supply module. 3 Power supply module
error protection 2 An error that needs to be handled with
immediate stop was detected in the power
supply module. (Regenerative overload,
overheating, etc.)
→Err69.3 occurs in all driver modules
connected to the power supply module.
4 Power supply module
error protection 3 With the power supply module, control
power supply undervoltage or EEPROM
error was detected.
→Err69.4 occurs in all driver modules
connected to the power supply module.
5 Inter-modules
communication ID setting
error protection

With the power supply module, the driver
module that the inter-module
communication node address is 1 could
not be found in the connected module
confirmation section after the control
power was turned on.
→Err69.5 occurs in all driver modules
connected to the power supply module.

In the driver module, the inter-module
communication node address on the front
panel was set to 0 when the control power
was turned on.
→Err69.5 occurs on the driver module that
detected the error.

Check that the DIP switches for power
supply module communication ID setup
on the front panel of the driver module is
set correctly.

Replace the power supply module.
6 Excess number of
driver module connection
error protection With the power supply module, detected
more than maximum number of connections
driver modules were connected in the
connected number confirmation section
after the control power was turned on.
→Err69.6 occurs in all driver modules
connected to the power supply module. Reduce the number of driver modules
connected to one power supply module to
the maximum number of connected
modules.
For maximum number of connections, refer
to "REFERENCE SPECIFICATIONS Power
supply module section (SX-DSV03452)".
