7.9 Other functions
7.9.9
Current address change function
With this function, the current address of a stopped axis changes arbitrarily.
Write the desired value to the current address (user) to change, followed by the current address (pulse)
update.
→
For parameters, control data and monitor data, refer to Chapter 11
Note
The current address does not change in the following states.
• READY/BUSY in the status information is OFF (0).
• Interruption due to a STOP command occurs and the operation is waiting for the remaining distance.
7.9.10
Zero return interlock function
This function disables the start command before mechanical return.
→
For the parameters, control data and monitor data, refer to Chapter 11
1. Applicable positioning operations
2. Setting items
When using the zero return interlock function, set to ON the "zero return interlock setting enabled/disabled"
bit.
Condition disabling the zero return interlock function
The zero return interlock function is disabled in the following cases:
• When the "zero return interlock setting enable/disabled" bit is set to "OFF"
• When the "zero return complete" flag is ON

information
BFM #28 b3
BFM #128 b3
Turns ON upon completion of mechanical zero return operation, or
when the current position is established by the absolute position
detection system.
Turns OFF at OFF-to-ON transition of a mechanical zero return
command, at power-off (reset), or when an absolute position is
lost during the absolute position detection system.
