%
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 / Automatic Restart
See Below
to-
-
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.
to-
: Following a Power On or Reset, the drive will automatically start if Digital Input 1 is closed.
to-
to
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 fault with, and will require the user to manually reset the fault.
DANGER! “

modes allow the drive to Auto-start, therefore the impact on system/Personnel
safety needs to be considered.

Keypad Start Mode
0

2
-
Options 0 to 3 are only active when P1-12 = 1 or 2 (keypad Mode). With these settings, the drive waits for the keypad start button to
be pressed before running.
0 : Minimum speed, keypad start.
Following a stop and restart, the drive will always initially run at the minimum speed P1-02.
1 : Previous speed, keypad start.
Following a stop and restart, the drive will return to the last keypad set-point speed used
prior to stopping.
2 : Current speed, keypad start.
Where the Optidrive 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, keypad start.
Following a stop and restart, the Optidrive 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 start.
Following a stop and restart, the drive will always initially run at the minimum speed P1-02.
5 : Previous speed, terminal start.
Following a stop and restart, the drive will return to the last keypad set-point speed used
prior to stopping.
6 : Current speed, terminal start.
Where the Optidrive 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 start.
Following a stop and restart, the Optidrive will always initially run at Preset Speed 4 (P2-04).

Mains Loss Stop / Ride Through
0

0
-
Controls the behaviour of the drive in response to a loss of mains power supply whilst the drive is enabled.
0 : Reserved.
1 : Coast to stop.
The Optidrive 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.
3 : DC bus supply mode.
