: Direction running
Adjustment range :0 or 1
0 (Forward) (Fd): The post-ramp reference is negative
(reverse).
1 (Reverse) (rSe): The post-ramp reference is positive
(forward).
Note: Do not take this parameter into account with the motor
stopped.
and :Not used
: Motor overload alarm
Adjustment range :0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when the motor current exceeds 110%
of the programmed motor rated current and the cumulative
overload exceeds 75% of the overload capacity of the motor.
If the motor current is not reduced, the drive will trip on fault I
x t, or will reduce the current automatically according to the
protection mode configured in 4.16.
: Drive overtemperature alarm
Adjustment range :0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when the measured temperature of the
IGBTs is higher than 100 °C, or when the drive automatically
reduces the configured switching frequency, owing to
overheating of the heatsink.
: Drive general warning
Adjustment range :0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when at least one of the alarms 10.12,
10.17 or 10.18 is activated.
to : Last 10 trips stored
Adjustment range :0 to 54
Contains the last 10 drive trips.
10.20: Indicates the most recent trip.
10.29: Indicates the oldest trip.
