Par. Name
P2-36 Start Mode Select / Automatic Restart
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 (e.g. Edge Triggered).

: Following a Power On or Reset, the drive will automatically start if Digital Input 1 is closed before power on.
 
to : Following a trip, the drive will make up to 5 attempts to restart at intervals defined by P6-03 (default 20 seconds).
The drive must be powered down or reset manually to reset the
drive fails to start on the final attempt, the drive will fault with, and will require the user to manually reset the fault.
P2-37 Keypad / Fieldbus Starting Control
This parameter controls the starting behaviour of the drive when operating in Keypad Mode or Fieldbus Mode (selected by P1-12).
Settings 0 to 3 are active in Keypad Mode only (P1-12 = 1 or 2), and define the speed at which the drive will initially operate following
the pressing of the keypad Start button.
0 : Minimum Speed, Keypad Start. Following a stop and restart, the drive will always initially run at the minimum speed set in P1-02.
This applies even if the drive is re-enabled whilst still decelerating the motor from the previous stop command.
1 : Previous Operating Speed, Keypad Start. Following a stop and restart, the drive will return to the last keypad setpoint speed used
prior to stopping.
2 : Current Running Speed. Where the Optidrive is configured for multiple speed references, when switched to keypad mode by a
digital input, the drive will continue to operate at the last operating speed. This setting can be used for 'Bumpless' changeover
between automatic and manual operating modes of the drive, e.g. typically Hand / Auto control or Local / Remote control.
3 : Preset Speed 8, Keypad Start. Following a stop and restart, the Optidrive will always initially run at Preset Speed 8 (P2-08)
4 : Minimum Speed, Terminal Start. Following a stop and restart, the drive will always initially run at the minimum speed P1-02. The
drive starting is controlled from the digital inputs, based on the setting of P1-13.
5 : Previous Operating Speed, Terminal Start. Following a stop and restart, the drive will return to the last keypad setpoint speed used
prior to stopping. The drive starting is controlled from the digital inputs, based on the setting of P1-13.
6 : Current Running 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. The drive starting is controlled from the digital inputs, based on the setting of P1-13.
7 : Preset Speed 8, Terminal Start. Following a stop and restart, the Optidrive will always initially run at Preset Speed 8 (P2-08). The
drive starting is controlled from the digital inputs, based on the setting of P1-13.
P2-38 Mains Loss Ride Through / Stop Control
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 Optidrive will attempt to continue operating by recovering energy from the motor and connected
load. Providing that the mains loss period is short (e.g. a 'Brown Out'), the drive enable control remains applied and that sufficient
energy can be recovered before the drive control electronics power off, the drive will automatically maintain motor operation (with
reduced output speed depending on the load), and recover back to the normal operating point on return of mains power.
Where the mains power supply is lost for a longer period (e.g. a 'Black Out') and there is insufficient kinetic energy available from the
load to maintain the drive electronic power supply, the restarting behaviour of the drive on return of the power supply will be
controlled by P2-36.
1 : Coast To Stop. On a loss of mains power supply, either 'Brown Out' or 'Black Out', 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, which may still be rotating when
the mains power returns, the Spin Start function (P2-26) should be enabled.
2 : Fast Ramp To Stop. On a loss of mains power supply, either 'Brown Out' or 'Black Out', the Optidrive will attempt to decelerate the
load to standstill at the rate programmed in the Fast deceleration time (P2-25), by recovering energy from the load. As the speed of
the load approaches zero, if the mains power supply has not been restored, the drive control electronics may power down shortly
before the load reaches a complete standstill. If the power returns whilst the drive is still decelerating the load, and the run signal is
maintained, the drive will resume operation and accelerate the load back to the operating speed.
3 : DC Power Supply. This option should be used where the drive is powered via the DC Bus terminals only, and no AC supply is
present.
P2-39 Parameter Access Lock
0 : Unlocked. All parameters can be accessed and changed
1 : Locked. Parameter values can be displayed, but cannot be changed
P2-40 Extended Parameter Access Code Definition
Defines the access code which must be entered in P1-14 to access parameter groups above Group 1.
