10.17 Overload alarm
Bit SP
Coding
1
Update rate Background write
This parameter is set if the drive output current is larger than 105% of motor rated current (Pr 5.07) and the overload accumulator is greater than 75%
to warn that if the motor current is not reduced the drive will trip on an I x t overload.
10.18 Drive over temperature alarm
Bit SP
Coding
1
Update rate Background write
Indicates that any of the heat sink temperatures (Pr 7.04 or Pr 7.05) or the control board temperature (Pr 7.06) are above their alarm level.
10.19 Drive warning
Bit SP
Coding
1
Update rate Background write
Indicates that one of the drive alarms is active, i.e. Pr 10.19 = Pr 10.12 OR Pr 10.17 OR Pr 10.18.

Range 0 to 230
Update rate Background write
Contains the last 10 drive trips. Pr 10.20 is the most recent trip and Pr 10.29 the oldest. When a new trip occurs all the parameters move down one,
the current trip is put in Pr 10.20 and the oldest trip is lost off the bottom of the log. Descriptions of the trips are given in the table below. A time stamp
can be stored for each trip (see Pr 10.41 to Pr 10.51). All trips are stored, including HF trips numbered from 17 to 32. (HF trips with numbers from 1 to
16 are not stored in the trip log.) UV trips are not stored unless the drive is running when the trip occurs. Any trip can be initiated by the actions
described or by writing the relevant trip number to Pr 10.38. If any trips shown as user trips are initiated the trip string is "txxx", where xxx is the trip
number.
