Specifications
Absolute encoder status error The rotation of the absolute encoder is higher than the specified value.
Encoder phase-Z error A phase Z pulse was not detected regularly.
Encoder CS signal error A logic error was detected in the CS signal.
External encoder communications error
An error was detected in external encoder connection and communications
data.
External encoder status error An external encoder error code was detected.
Phases-A, B and Z connection error An error occurred in connection of phases A, B, and Z of external encoder.
Node address setting error
At power-on, the rotary switches for node address setting were set in any
value outside the specified range.
Communications error
The errors not to receive the expected data from the MECHATROLINK-II
communications cycles occurred continuously, and exceeded the number
of times set in the Communications Control (Pn800).
Transmission cycle error
During the MECHATROLINK-II communications, synchronization frames
(SYNC) were not received in conformity with the transmission cycles.
Watchdog data error
An error occurred in the synchronization data that was exchanged between
the master and slave nodes during each MECHATROLINK-II
communications cycle.
Emergency stop input error The emergency stop input circuit opened.
Transmission cycle setting error
The transmission cycle setting was incorrect when the MECHATROLINK-II
CONNECT command was received.
SYNC command error
A SYNC-related command was issued while MECHATROLINK-II was in
asynchronous communications mode.
Parameter setting error
The electronic gear ratio is outside the allowable parameter setting range;
either it is smaller than 1/100 x or larger than 100 x.
Motor non-conformity The combination of the Servomotor and Servo Drive is not appropriate.
The encoder was not connected when the power supply was turned ON.
