SPINDL PRESET
Selects the various Spindle Mode parameters and performance detectors.
Overspd Trip
Sets the overspeed trip point . The drive will shut down at this point and
cause the motor to coast to a stop. Set this parameter at least 10% higher
than expected maximum speed to avoid nuisance trips.
Data Range: RPM 00000 to 30000
Default Value: 08000
Acc Rate #1
Sets the acceleration rate ramp generator for the ramp rate that is used in
spindle mode when the Accel/Decel Rate Select input is turned Off. The
rate is defined in seconds/1000 rpm of speed change. This accel/decel
rate is achieved only if the required torque does not exceed the torque
limit level.
Data Range: S/KRPM 000.00 to 009.99
Default Value: 001.00
Acc Rate #2
Sets the acceleration rate ramp generator for the ramp rate that is used in
spindle mode when the Accel/Decel Rate Select input is On. The rate is
defined in seconds/1000 rpm of speed change. This accel/decel rate is
achieved only if the required torque does not exceed the torque limit
level.
Data Range: S/KRPM 000.00 to 009.99
Default Value: 001.00
Low Torq Lmt
This parameter sets the level of torque limit used when the Low Torque
Limit Select input is On. The torque is defined as a percent of the
continuous rated torque of the specific motor/drive combination and
cannot exceed the peak torque capacity of the motor (1.2 x 30 minute
motor rating).
Data Range: % 000 to 250
Default Value: % 025
At-Set-Speed
This parameter determines how close the actual speed must be to the
commanded speed before the At Speed Indicator output is On. The data is
stated as a percent of the commanded speed. If the percent of commanded
speed gives a value less than 25 rpm, then a fixed
±
25 rpm band is used
for the test.
Data Range: % 000 to 100
Default Value: % 010
