8 − 9
(3) Permissible droop pulse value
(a) This is the setting for the permissible number of droop pulses at the
deviation counter.
(b) The deviation counter value is continually monitored, and if it becomes
larger than the permissible droop pulse value, the error detection signal
(M2407+20n) comes ON.
(c) When the motor connected has feedback pulses of 131072 PLS, set the
value which is found by dividing the actual permissible droop pulse value by
100.
(4) Stroke limit upper limit value/lower limit value
(a) This is the setting for the stroke range in the virtual mode.
(b) If the stroke range is exceeded during operation, the error detection signal
(M2407+20n) comes ON.
However, ball screw shaft stop processing is not executed.
(5) Speed limit value (V
L
)
(a) This is the setting for the maximum speed of the ball screw.
(b) Set the speed limit value within the following range.
1) When the units are millimeters
1 ≤≤ 1000000 [PLS/s]
2) When the units are inches
1 ≤≤ 1000000 [PLS/s]
(c) If the speed of the ball screw shaft exceeds the speed limit value, the error
detection signal (M2407+20n) comes ON.
However, the ball screw speed is not clamped.
V
Even if the speed limit value is exceeded,
control is executed at the set speed.
Setting for speed limit value
(6) Limit switch output
(a) This setting determines whether or not a limit switch signal is output for the
ball screw shaft.
• Limit switch output used.................. Limit switch signal is output based on
the ball screw's real current value.
• Limit switch output not used............Limit switch signal is not output.
