Information information
10.16 Under voltage active
Drive mode Regen
Bit SP
Coding
1
Update rate Background
This parameter indicates that the under voltage condition is active. Normally this condition exists when the UU trip is also active. However, when the
drive first powers up it remains in the under voltage state (i.e. this parameter is active) until the DC bus voltage exceeds the under voltage restart level
(see Pr 10.16 on page 148). As the UU trip voltage level is lower than the under voltage restart level this parameter is active, but a UU trip is not active
at power up until the DC bus voltage exceeds the under voltage restart level.
10.17 Overload alarm
Drive mode Regen
Bit SP
Coding
1
Update rate Background
This parameter is set if the drive output current is larger than 105% of 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 Ixt overload. (If the rated current (Pr 5.07) is set to a level above the rated drive
current (Pr 11.32) the overload alarm is given when the current is higher than 100% of rated current.)
10.18 Drive over temperature alarm
Drive mode Regen
Bit SP
Coding
1
Update rate Background
Indicates that either the heatsink temperature is greater than or equal to 90°C, or the control board temperature is greater than or equal to 90°C, or
the IGBT junction temperature calculated from the drive thermal model is above 135°C (see Pr 5.18 on page 109 and Pr 7.06 on page 122).
10.19 Drive warning
Drive mode Regen
Bit SP
Coding
1
Update rate Background
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 Regen
Update rate Background
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.
