Indicates that the current limits are active.
Indicates that power is being transferred from the motor to the drive.
Indicates that the Braking IGBT is active. If the IGBT becomes active this parameter is held on for at least 0.5s so that it can be seen on the display.
This parameter is set when the braking IGBT is active and the braking energy accumulator is greater than 75%. This parameter is held on for at least
0.5s so that it can be seen on the display.
This parameter is one if the pre-ramp reference (Pr 1.03) is negative, and zero if the pre-ramp reference is zero or positive.
This parameter is one if the speed feedback (Pr 3.02) is negative, or zero if the speed feedback is zero or positive.
Indicates that the drive has detected mains loss from the level of the DC bus voltage. This parameter can only become active if mains loss ride
through or mains loss stop modes are selected (see Pr 6.03 on page 89).
This parameter indicates that the under voltage condition is active. Normally this condition exists when the UV 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 6.03 on page 89). As the UV trip voltage level is lower than the under voltage restart level this parameter is active, but a UV trip is not active
at power up until the DC bus voltage exceeds the under voltage restart level.
