:Deceleration mode
Adjustment range : 0 to 2
Factory setting : 1
0: Standard deceleration ramp. If the
deceleration ramp which has been set is
too fast in relation to the inertia of the load,
the DC bus voltage exceeds its maximum
value and the drive switches to overvoltage
fault "OU".
1 : Standard deceleration ramp with
automatic extension of the ramp time in
order to avoid causing a DC bus
overvoltage fault on the drive.
2 : The drive allows the motor voltage to be
increased to 1.2 times the rated voltage set
in 0

(motor rated voltage), to avoid
reaching the maximum DC bus voltage
threshold.
However, if this is not adequate, the
standard deceleration ramp time is
extended, to avoid causing a DC bus
overvoltage fault on the drive.
Mode 2 offers faster deceleration than
mode 1, for the same amount of energy,
assuming that the motor can withstand the
losses.
• If a braking resistor is connected
to the drive, it is essential to set

:Stop mode
Adjustment range : 0 to 3

CAUTION:
During operation, opening the unlock
terminal (terminal 9), causes the motor
to stop in free wheel mode, regardless

0: freewheel stop.
The power bridge is deactivated as soon as
the stop command is given.
The drive cannot receive another run
command for 2s, the motor
demagnetisation time.
The display indicates "rd" 2s after the stop
command. The machine stopping time
depends on its inertia.
