if the signal level falls below 3mA

P2-31 is used to scale the analog input prior to being applied as a reference to the drive. For example, if P2-30 is set for 0 – 10V, and
the scaling factor is set to 200.0%, a 5 volt input will result in the drive running at maximum speed (P1-01)

%
P2-32 defines an offset for the analog input, as a percentage of the full range of the input. A positive offset is deducted from the
incoming analog signal and a negative offset is added to the signal. For example, if P2-30 is set for 0 – 10V, and the analog offset is set
to 10.0%, then 1 volt (10% of 10V) will be deducted from the incoming analog reference prior to it being applied.

P2-35 defines an offset for the analog input, as a percentage of the full range of the input. A positive offset is deducted from the
incoming analog signal and a negative offset is added to the signal. For example, if P2-33 is set for 0 – 10V, and the analog offset is set
to 10.0%, then 1 volt (10% of 10V) will be deducted from the incoming analog reference prior to it being applied.

Start Mode Select

-
Defines the behaviour of the drive relating to the enable digital input and also configures the Automatic Restart function.
: Following Power on or reset, the drive will not start if Digital Input 1 remains closed. The Input must be closed after a power
on or reset to start the drive.
: Following a Power On or Reset, the drive will automatically start if Digital Input 1 is closed.
to
: Following a trip, the drive will make up to 5 attempts to restart at 20 second intervals. The drive must be powered
down to reset the counter
.
The numbers of restart attempts are counted, and if the drive fails to start on the final attempt the drive
will trip with the fault and will require the user to manually reset the drive.

-
Options 0 to 3 are only active when P1-12 = 1 or 2 (keypad Mode)
0 : Minimum Speed. Following a stop and restart, the drive will always initially run at the minimum speed P1-02
1 : Previous Operating Speed. Following a stop and restart, the drive will return to the last keypad set-point speed used prior to
stopping
2 : Current Running Speed. Where the drive is configured for multiple speed references (typically Hand / Auto control or Local /
Remote control), when switched to keypad mode by a digital input, the drive will continue to operate at the last operating speed
3 : Preset Speed 4. Following a stop and restart, the drive will always initially run at Preset Speed 4 (P2-04)
Options 4 to 7 are only active in all control modes. Drive starting in these modes is controlled by the enable digital input on the control
terminals.
4 : Minimum Speed (Terminal Enable). Following a stop and restart, the drive will always initially run at the minimum speed P1-02
5 : Previous Operating Speed (Terminal Enable). Following a stop and restart, the drive will return to the last keypad set-point speed
used prior to stopping
6 : Current Running Speed (Terminal Enable). Where the drive is configured for multiple speed references (typically Hand / Auto
control or Local / Remote control), when switched to keypad mode by a digital input, the drive will continue to operate at the last
operating speed
7 : Preset Speed 4 (Terminal Enable). Following a stop and restart, the drive will always initially run at Preset Speed 4 (P2-04)

Mains Loss Stop Mode

0
-
Controls the behaviour of the drive in response to a loss of mains power supply whilst the drive is enabled.
0: Mains Loss Ride Through. The drive will attempt to continue operating by recovering energy from the load motor. Providing that
the mains loss period is short, and sufficient energy can be recovered before the drive control electronics power off, the drive will
automatically restart on return of mains power
1: Coast To Stop. The drive will immediately disable the output to the motor, allowing the load to coast or free wheel. When using this
setting with high inertia loads, the Spin Start function (P2-26) may need to be enabled
2: Fast Ramp To Stop. The drive will ramp to stop at the rate programmed in the Fast deceleration time P2-25
