(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.
However, since operation of the roller shaft continues, the user must
execute the appropriate error processing.
(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) Speed control limit (V
L
)
(a) This is the setting for the maximum speed of the roller shaft.
(b) Set the speed limit value within the following range.
1 ≤≤ 1000000 [PLS/s]
(c) If the speed of the roller shaft exceeds the speed limit value, the error
detection signal (M2407+20n) comes ON.
However, the roller shaft 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
(5) Torque limit value setting device (1 word)
(a) This sets the device which stores the setting for the torque limit value for the
roller shaft.
Once the device has been set, torque control is executed in accordance
with the setting stored in this device.
In the virtual mode, the torque limit setting is always valid.
If no device setting is made, the torque limit is set at 300%.
(b) The following devices can be set as the torque limit setting device.
Data register
(Note)
D800 to D3069
D3080 to D8191
Link register W0 to W1FFF
(Note): D800 to D1559 are devices dedicated to the virtual servo motor axes,
synchronous encoder axes and output module "cams" in the virtual mode.
The areas of the unused virtual servo motor, synchronous encoder and cam
axes are available for the user.
(c) The setting range for the torque limit value is 1 to 500%.
(6) Comment
(a) A comment is created for purposes such as describing the application of the
roller shaft.
If a comment is created, it can be displayed when monitoring at a peripheral
device.
(b) Comments up to 32 characters long can be created.
