Note (1) All warnings are retained. After resolving the problem, clear the alarms and the warnings.
A.42 402A PR Absolute encoder over-
speed error The Servomotor rotation speed exceeded the specified
value when power to the absolute encoder is supplied by the
battery only.
A.44 402C PR Absolute encoder one-turn
counter error A one-turn counter error was detected.
A.45 402D PR Absolute encoder multi-turn
counter error A multi-turn counter error or phase-AB signal error was
detected.
A.47 402F --- Absolute encoder status
error The rotation of the absolute encoder is higher than the spec-
ified value.
A.48 4030 PR Encoder phase Z error A phase-Z pulse was not detected regularly.
A.49 4031 PR Encoder PS signal error A logic error was detected in the PS signal.
A.82 4052 PR Node address setting error The rotary switch for setting the node address of the Servo
Drive was set out of range.
A.83 4053 --- Communications error Data received during each MECHATROLINK-II communica-
tions cycle repeatedly failed, exceeding the number of times
set in the Communications Control (Pn005).
A.84 4054 --- Transmission cycle error While actuating MECHATROLINK-II communications, syn-
chronization frames (SYNC) were not received according to
the transmission cycle.
A.86 4056 --- Watchdog data error Synchronization data exchanged between the master and
slave nodes during each MECHATROLINK-II communica-
tions cycle resulted in an error.
A.87 4057 X Emergency stop input error The emergency stop input became OPEN.
A.90 405A --- Transmission cycle setting
error The transmission cycle setting error when the MECHA-
TROLINK-II CONNECT command is received.
A.91 405B --- SYNC command error A SYNC-related command was issued while MECHA-
TROLINK-II was in asynchronous communications mode.
A.93 405D PR Parameter setting error Parameter setting exceeded the allowable range.
A.95 405F PR
X
Servomotor non-conformity The combination of the Servomotor and Servo Drive is not
appropriate.
Others Others PR Other errors The control circuit malfunctioned due to excessive noise.
An error occurred within the Servo Drive due to the activa-
tion of its self-diagnosis function.
