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.
Open-loop
This parameter is one if the post-ramp reference (Pr
2.01
) is negative, or zero if the post-ramp reference is zero or positive.
Closed-loop vector and Servo
This parameter is one if the speed feedback (Pr
3.02
) is negative, or zero if the speed feedback is zero or positive.
Open-loop, Closed-loop vector and Servo
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
Regen
This parameter is the inverse of Pr
3.07
.
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
on page 135). 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.
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 maximum
heavy duty current (Pr
11.32
) the overload alarm is given when the current is higher than 101% of rated current).
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.
