Cumulative Operation Time Alarm Setting
Program Protection Special Protection Parameters
This parameter sets a run-time value that, once exceeded, closes a contact. The
output signal may be used to control external equipment or used to engage a
brake.
Note:
The time displayed is 1/10th of the actual time (0.1 hr. = 1.0 hr.).
Abnormal Speed Detection Time
Program Protection Abnormal Speed Settings
This parameter sets the time that an over-speed condition must exist to cause a
trip.
This parameter functions in conjunction with the settings of
Over-Speed Detection Frequency Upper Band (0 = disabled)
Program Protection Abnormal Speed Settings
This parameter sets the upper level of the Base Frequency range that, once
exceeded, will cause an Over-Speed Detected alert.
This parameter functions in conjunction with the settings of
Over-Speed Detection Frequency Lower Band (0 = disabled)
Program Protection Abnormal Speed Settings
This parameter sets the lower level of the Base Frequency range that, once
exceeded, will cause a Speed Drop Detected alert.
This parameter functions in conjunction with the settings of
Over-Voltage Limit Operation Level (fast)
Program Protection Stall
This parameter sets the upper DC bus voltage threshold that, once exceeded,
will cause an Over-Voltage Stall. An Over-Voltage Stall increases the output
frequency of the drive during deceleration for a specified time in an attempt to
prevent an Over-Voltage Trip.
If the over-voltage condition persists for more than 250 µS, an Over-Voltage
Trip will be incurred.
Note:
This feature may increase deceleration times.
