6.6 Operation Speed Change Function
This function changes the speed of the positioning operation to the specified speed.
When starting the positioning operation, the value of the operation speed I (BFM#20, #19) is written to the
operation speed change value (BFM#56, #55).
Then, when a new value is written to the operation speed change value, the operation speed changes.
When the 2-speed is changed in the 2-speed positioning operation, interrupt 2-speed positioning operation
and external command positioning operation, the value of the operation speed II (BFM#24, #23) is written to
the operation speed change value after the operation at the first speed is completed. Then, when a new value
is written to the operation speed change value, the operation speed changes.
Point
• Even when a value is written to the operation speed change value, the operation speed I and the operation
speed II values do not change.
• In case of positioning operations for which the operation speed change function is invalid, the operation
speed is not written to the operation speed change value.
The operation speed change value remains as what was written for the last time.
• When the operation is stopped by the STOP command and the remaining distance operation is executed
after the operation speed is changed, operation resumes with the changed speed.
