A.94 ON ON OFF Data setting warning A value was set out of range using
MECHATROLINK-II communications.
• Check whether a data address or the data
specified by the host controller (with the
host Support Software) was set out of
range.
• If connected to an MCH Unit, the Option
Monitor (Servo Driver parameter) may not
be set correctly. Check whether Pn813 is
set to 0032 (hex) and, if not, set it to 0032.
A.95 OFF ON OFF Command warning Preparations were not ready to execute a
command received by MECHATROLINK-II
communications, and therefore the
command was not executed.
• This warning occurs in the following cases.
Discontinue the operation that caused the
warning, and try again.
• An attempt was made to execute a servo
lock while the Servo Driver’s main circuit
was OFF.
• Host controller (including the host Sup-
port Software) or Servo Driver parame-
ters were read or written while commu-
nications with WMON were in progress.
• The same node number is set twice.
A.96 ON OFF OFF Communications
warning
A communications error was detected. If it
occurs two consecutive times, an A.E6
communications error will occur.
• The same node number is set twice. Cor-
rect the node numbers, and then execute
the communications again.
• The communications may be affected by
noise from peripheral devices, or by vibra-
tion or shock. Implement measures against
noise, such as separating the communica-
tions cable from the main-circuit power
supply lines.
