b40.14 Serial communication enable . Default=0. Set this parameter to 1 to enable serial
comms.
b40.15 Reserved. Must remain on zero .
b41.0 Overspeed . When the absolute motor speed value exceeds the value set in Pr13,
b41.0 is on 1, otherwise it is on 0.
b41.1 At speed . With b40.7=0 if the speed difference between motor and reference is lower
than Pr14 and higher than Pr15, b41.1 will be 1, otherwise it will be 0. With b40.7=1,
if motor speed is lower than Pr14 and higher than Pr15, b41.1 will be 1, otherwise it
will be 0.
b41.2 Zero speed . If motor speed (Pr0) is zero rpm, b41.2=1, otherwise b41.2=0.
b41.3 Forward . If motor speed (Pr0) is positive b41.3=1, otherwise b41.3=0.
b41.4 Drive Healthy . If =1 no alarms are present, otherwise =0.
b41.5 Hardware enable status . 1 when hardware enable is set.
b41.6 Temperature pre-alarm . 10 degrees before reaching the maximum temperature of
the power stage, b41.6 is set to 1.
b41.7 External alarm . Alarm for user’s equipment.
b41.8 Auxiliary alarm . Second alarm for user’s equipment.
b41.9 Calibration failed . b41.9=1 indicates that initial calibration of current offsets has
terminated incorrectly.
b41.10 Speed control saturation . b41.10=1 when the speed control loop is delivering
maximum current.
b41.11 I2T active . Indicates that Pr36 has reached 100.0 % and therefore the drive is
restricting current to the rated value.
b41.12 Drive enabled .
b41.13 Keypad fault . b41.12=1 if communication between keypad and drive has failed.
b41.14 External operating mode. If set to 1 an external operating mode is installed.
b41.15 External operating mode time slot. If set to 1 indicates that the external operating
mode is controlled at 2 ms intervals otherwise at 512

Default value is 1024
b42.4 24V over current. Digital output trip.
b42.5 Frequency input (board X6). If set to 1 the frequency input is programmed to
receive two phases in quadrature. This is the default. If set to 0 it is enabled to
receive a frequency/direction type input.
