-1 Error List
48080000 FPGA WDT Error An FPGA error was
detected. • False detection due to a
data read error that was
caused by excessive noise
• Hardware failure
√ P. A-152
64E30000 Drive Prohibition
Input Error Both the Positive Drive Pro-
hibition (POT) and the Neg-
ative Drive Prohibition Input
(NOT) turned ON. • An error occurred on the
switch, wire, power supply,
and wiring that were con-
nected to the Positive Drive
Prohibition (POT) or Nega-
tive Drive Prohibition Input
(NOT)
• False detection occurred
because the control signal
power supply was turned
ON slowly
√
P. A-153
68200000 Drive Prohibition
Detected The operation was stopped
according to the user setting
because the motor ran in
the prohibited direction
when the Drive Prohibition
was enabled. • Incorrect or broken wiring of
Positive Drive Prohibition
Input (POT) or Negative
Drive Prohibition Input
(NOT)
• Incorrect setting of the Drive
Prohibition Input
√ P. A-154
68210000 Control Right
Release Error Communications between
the Sysmac Studio and
Servo Drive were inter-
rupted while a specific func-
tion was used from the
Sysmac Studio. • The USB cable or EtherCAT
cable was disconnected
during the connection with
the Sysmac Studio
• There is excessive noise
• A command sent from the
Sysmac Studio was not sent
to the Servo Drive because
the computer was in a busy
state or the like
√ P. A-155
68220000 Error Stop Input The Error Stop Input
(ESTP) is active. • The Error Stop Input
(ESTP) was input
• The Error Stop Input
(ESTP) is incorrectly wired
√ P. A-156
68230000 Software Limit
Exceeded The Position actual value
detected the position that
exceeded the value set in
the Software Position Limit,
and stopped the operation
according to the user set-
ting. • Incorrect setting of Software
Position Limit
• When the Software Posi-
tion Limit - Stop Selection
was set to Stop according to
the setting of Fault reaction
option code
, the position
exceeded the value set in
the Software Position Limit
√
P. A-156
78200000 Pulse Output Over-
speed Error The speed, which exceeded
the frequency that could be
output by the Encoder
Dividing Pulse Output func-
tion, was detected. • The dividing ratio setting is
inappropriate for the actual
usage condition
