Emerson unidrive m200 - Auto-Reset Delay; Auto-Reset Hold Drive Healthy; Action on Trip Detection

trips the minimum is 10s. The auto-reset count is only incremented when the trip is the same as the previous trip otherwise it is reset to 0. When the auto-reset count
reaches the programmed value, any further trip of the same value will not cause an auto-reset. If there has been no trip for 5 minutes then the auto-reset count is
cleared. Auto reset will not occur after any trips with priority levels 1, 2 or 3 as defined in the Trips section of this guide. When a manual reset occurs the auto-reset
counter is reset to zero.
If NumberOfAuto-resetAttempts (10.034) = 6 the auto-reset counter is held at zero, and so there is no limit on the number of auto-reset attempts.

If Auto-resetHoldDriveHealthy (10.036) = 0 then DriveHealthy (10.001) is cleared every time the drive trips regardless of any auto-reset that may occur. If Auto-
resetHoldDriveHealthy (10.036) = 1 then DriveHealthy (10.001) is not cleared on a trip if any further auto-reset attempts are possible. Note that if the under
voltage state becomes active DriveHealthy (10.001) is always set to zero.

The bits in ActionOnTripDetection (10.037) are defined as follows:
Bit 0: Stop on defined non-important trips
If bit 0 is set to one the drive will attempt to stop before tripping if any of the following trip conditions are detected: I/OOverload, KeypadMode, MotorTooHot,
EEPROMFail or user 24V failure.
Bit 1: Braking resistor overload detection
0 = trip, 1 = Disable brake IGBT.
See BrakingResistorRatedPower (10.030).
Bit 2: Disable phase loss stop
Normally the drive will stop when the input phase loss condition is detected. If this bit is set to 1 the drive will continue to run and will only trip when the drive is
brought to a stop by the user.
Bit 4: Disable parameter freeze on trip
If this bit is 0 then the parameters listed below are frozen on trip until the trip is cleared. If this bit is 1 then this feature is disabled.

Because of the limited number of segments on drives with an LED display, these drives will indicate the parameter value as a
decimal value rather than a binary value.
