3. Setup
Details
Set the cycle to add the increment values in the dual
cushion process.
When this setting value is increased, the dual cushion will
increase, and the changes in the speed during
acceleration/deceleration will become gradual.
For an acceleration/deceleration time constant defined in
SP019 (CSN1) , this parameter is used to provide smooth
movement only at the start of acceleration/deceleration.
As the value of this parameter is smaller, it moves
smoother but the acceleration/deceleration time becomes
longer.
To make this parameter invalid, set "0".
Set the reset hysteresis width for a speed detection set
value defined in SP020 (SDTS).
Set the speed deviation rate with respect to the
commanded speed for output of the speed reach signal.
Set the torque limit rate for the torque limit signal 010.
Set the torque limit rate for the torque limit signal 011.
Set the torque limit rate for the torque limit signal 100.
Set the torque limit rate for the torque limit signal 101.
Set the torque limit rate for the torque limit signal 110.
Set the torque limit rate for the torque limit signal 111.
Set the timer value until the excessive speed deviation
alarm is output.
The value of this parameter should be longer than the
acceleration/deceleration time.
Set the minimum value of the variable excitation rate.
Select a smaller value when gear noise is too high.
Set the value for judging when changing the speed
command from a constant to acceleration/deceleration.
Set the motor speed for carry out speed detection 2
output.
Set the base shut-off time for contactor switching at coil
changeover.
Note that the contactor may be damaged with burning if
the value of this parameter is too small.
Set the current limit time to be taken after completion of
contactor switching at coil changeover.
Set the current limit value during a period defined in
SP060 (MKT2) after completion of contactor switching at
coil changeover.
Not used. Set to "0".
Set the time constant for detection of the motor overload
alarm.
Set the detection level of the motor overload alarm.
Set the magnification of speed loop proportional gain with
respect to SP022 (VGNP1) at the maximum motor speed
defined in SP017 (TSP).
Set the speed when the speed loop proportional gain
change starts.
