Meaning Assumed cause
A mistake was • When bit 09 (Remote) of the
made in using a Statusword (6041 hex) was set
command. to 1 (remote), and the Servo
Drive was in operation enabled
state (Servo ON), a command
was received that changes the
communications state from
Operational to another state
(Init, Pre-operational, or Safe-
operational state).
• When bit 09 (Remote) of the
Statusword (6041 hex) was set
to 0 (local), a command was
received during FFT or test run
status that changes the ESM
state from Operational, Safe-
operational, or Pre-operational
state to Init state.
• An unsupported number was
set for 6060 hex (Operation
Mode).
• During Fully-closed Control
Mode, csv or cst was set for
6060 hex (Operation Mode)
(This applies to Cylinder-type
Servomotors.).
• The setting of 6060 hex (Oper-
ation Mode) was changed at an
interval of less than 2 ms.
• Homing was started when 6098
hex (Homing Method) was set
to a value other than 8, 12, 19,
20, 33, 34,or 35.

number of data setting warn-
ings that is set in 3781 hex

tion Count).
