Recovery Method
Recovery Conditions
All of the following conditions must be met.
•
All safety request inputs are ON.
•
The Servo ON command (Enable Operation command) was not sent.
•
None of the following utility functions have been executed. (These functions execute the
Servo ON command (Enable Operation command).)
The following utility functions execute the Servo ON command (Enable Operation command).
Note: If any of the above utility functions was executed, the utility function must be ended. Perform the operation to
return to the Main Menu for the utility functions on the Digital Operator. Refer to the following manual for oper-
ating procedures.

Recovery Procedure
1.
Specify Shutdown in
controlword
(6040 hex, bits 0 to 3) to reset the Servo Drive.
2.
Specify Switch ON and the Servo ON command (Enable Operation command) in
con-
trolword
(6040 hex, bits 0 to 3).
Power will be supplied to the motor.

Detecting Errors in HWBB Signal
If only the /HWBB1 or the /HWBB2 signal is input, an A.Eb1 alarm (Safety Function Signal Input
Timing Error) will occur unless the other signal is input within 10 seconds. This makes it possi-
ble to detect failures, such as disconnection of an HWBB signal.

CAUTION
The A.Eb1 alarm (Safety Function Signal Input Timing Error) is not a safety-related element.
Keep this in mind when you design the system.
