B-63530EN/03 4.DESCRIPTION OF PARAMETERS
- 159 -
1885 Maximum allowable value for total travel during torque control
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 0 to 32767
This parameter sets the maximum allowable value for the total travel
(error counter value) for an axis placed under torque control, as
specified by the axis control command of the PMC axis control
function. If the total travel exceeds the parameter-set value while
torque control is applied, a servo alarm (No.423) is generated.
NOTE
This parameter is enabled when bit 4 (TQF) of
parameter No.1803 is 0 (follow-up is not performed
during torque control).
1886 Positional deviation when torque control is canceled
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 0 to 32767
This parameter sets the positional deviation used when torque control,
performed for an axis according to the axis control command of the
PMC axis control function, is canceled and position control is
resumed. After the positional deviation has fallen to the parameter-set
value, switching to position control is performed.
NOTE
This parameter is enabled when bit 4 (TQF) of
parameter No.1803 is 0 (follow-up is not performed
during torque control).
1890 Servo motor speed for detection
NOTE
When this parameter is set, the power must be
turned off before operation is continued.
[Data type] Word
[Unit of data] min
-1
[Valid data range] 0 to 8000
The servo motor speed of each axis is monitored and a motor speed
detection signal is output indicating whether the speed of each axis
exceeds the value set in this parameter (set in the Y address specified
in parameter No.1891)
NOTE
No motor speed detection signals are output when
the servo/spindle motor speed detection function is
not used or 0 is set in this parameter.
