Normal timing times Unit : [ms]
t1 t2 t3 t4
1 to 60 0 to 60 120 to 180 1 to 60
Delays may occur in the t1 timing time due to the following factors.
1) The operation status of other axes.
2) Whether there is intervention from a peripheral device during processing
the start process.
3) Details of the positioning data to be started.
Position control by manual pulse generator operation
The command output during manual pulse generator operation is as follows.
[No. of command pulses] = [No. of manual pulse generator input pulse]

*: When the manual pulse generator input frequency changes, the new frequency
will apply after a maximum of 180ms delay.
