(b) The travel value per pulse is calculated from the number of pulses per rotary
table revolution in accordance with the following formula:
360
[Travel value per pulse] =
N
D
[degree]
(2) Permissible droop pulse value
(a) This device is used to set the permissible droop pulse value of deviation
counter.
(b) The deviation counter value is continually checked, and if it becomes larger
than the permissible droop pulse value, the error detection signal
(M2407+20n) turns on.
However, since the rotary table axis operation continues, execute the error
processing by user side.
(3) Upper/lower stroke limit value
(a) This device is used to set the stroke range in the virtual mode.
The upper/lower stroke limit setting determines whether the stroke limit is
valid or not. If the upper stroke limit value is equal to the lower stroke limit
value, the stroke limit is invalid.
(b) When it exceeds the stroke range during operation, the error detection signal
(M2407+20n) turns on.
However, a stop processing of rotary table axis is not executed.
(4) Speed limit value (V
L
)
(a) This device is used to set the maximum speed of rotary table axis.
(b) Set the speed limit value within the following range.

(c) When the rotary table axis speed exceeds the speed limit value, the error
detection signal (M2407+20n) turns on.
However, the rotary table axis speed is not clamped.

Even if the speed limit value is exceeded,
it controls with the setting speed.
