Acceleration Ramp Time
See Below
5.0 / 10.0
Seconds
Acceleration ramp time from 0 to base speed (P1-09) in seconds.
FS2 & FS3 : 5.0 Seconds Default Setting, 0.01 Seconds Resolution, 600.0 Seconds Maximum.
FS4 – FS7 : 10.0 Seconds Default Setting, 0.1 Seconds Resolution, 6000 Seconds Maximum.
P1-04
Deceleration Ramp Time
See Below
5.0 / 10.0
Seconds
Deceleration ramp time from base speed (P1-09) to standstill in seconds. When set to zero, it will coast to stop the motor.
FS2 & FS3 : 5.0 Seconds Default Setting, 0.01 Seconds Resolution, 600.0 Seconds Maximum.

Ramp
When the enable signal is removed, the drive will ramp to stop, with the rate controlled by
P1-04 as described above. In this mode, the drive brake transistor (where fitted) is disabled.
1
Coast
When the enable signal is removed, the drive output is immediately disabled, and the motor
will coast (freewheel) to stop. If the load can continue to rotate due to inertia, and the drive
may possibly be re-enabled whilst the motor is still rotating, the spin start function (P2-26)
should be enabled. In this mode, the drive brake transistor (where fitted) is disabled.
2
Ramp, brake chopper
enabled
When the enable signal is removed, the drive will ramp to stop, with the rate controlled by
P1-04 as described above. The BFI drive Brake chopper is also enabled in this mode.
3
Coast, brake chopper
enabled
When the enable signal is removed, the drive output is immediately disabled, and the motor
will coast (freewheel) to stop. If the load can continue to rotate due to inertia, and the drive
may possibly be re-enabled whilst the motor is still rotating, the spin start function (P2-
26) should be enabled. The drive brake chopper is enabled in this mode, however it will
only activate when required during a change in the drive frequency setpoint, and will not
activate when stopping.

AC Flux Braking
As Option 0, but additionally, AC Flux braking is used to increase the available braking
torque.

Enabled
When enabled, the Energy Optimiser attempts to reduce the overall energy consumed by
the drive and motor when operating at constant speeds and light loads. The output voltage
applied to the motor is reduced. The Energy Optimiser is intended for applications where
the drive may operate for some periods of time with constant speed and light motor load,
whether constant or variable torque.

Motor Rated Voltage / kE
Drive Rating Dependent
Volts
This parameter should be set to the rated (nameplate) voltage of the motor.
P1-08
Motor Rated Current
Drive Rating Dependent
