0.000 s / real32 Defines the shape of the acceleration ramp at the end
of the acceleration. See parameter
23.16 Shape time
acc 1 .
Shape time acc 2 23.17
10 = 1 s / 1000 = 1 s Ramp shape at end of acceleration. 0.000 ... 1800.000 s
0.000 s / real32 Defines the shape of the deceleration ramp at the
beginning of the deceleration. See parameter
23.16
Shape time acc 1 .
Shape time dec 1 23.18
10 = 1 s / 1000 = 1 s Ramp shape at start of deceleration. 0.000 ... 1800.000 s
0.000 s / real32 Defines the shape of the deceleration ramp at the end
of the deceleration. See parameter
23.16 Shape time
acc 1 .
Shape time dec 2 23.19
10 = 1 s / 1000 = 1 s Ramp shape at end of deceleration. 0.000 ... 1800.000 s
60.000 s / real32 Defines the acceleration time for the jogging function
i.e. the time required for the speed to change from zero
to the speed value defined by parameter
46.1 Speed
scaling .
See section Jogging (page 99) .
Acc time jogging 23.20
10 = 1 s / 1000 = 1 s Acceleration time for jogging. 0.000 ... 1800.000 s
60.000 s / real32 Defines the deceleration time for the jogging function
i.e. the time required for the speed to change from the
speed value defined by parameter
46.1 Speed scaling
to zero.
See section
Jogging (page 99) .
Dec time jogging 23.21
10 = 1 s / 1000 = 1 s Deceleration time for jogging. 0.000 ... 1800.000 s
3.000 s / real32 In speed control mode, this parameter defines the
deceleration rate for emergency stop Off3 as the time
it would take for the speed to decrease from the value
of parameter
46.1 Speed scaling . This also applies to
torque control because the drive switches to speed
control on receiving an emergency stop Off3 command.
In frequency control mode, this parameter specifies
the time it would take for the frequency to decrease
from the value of
46.2 Frequency scaling to zero.
The emergency stop mode and activation source are
selected by parameters
21.4 Emergency stop mode and
21.5 Emergency stop source respectively. Emergency
stop can also be activated through fieldbus.
Note: Emergency stop Off1 uses the standard
deceleration ramp as defined by parameters
23.11 … 23.19 (speed and torque control) or 28.71 … 28.75
(frequency control).
Emergency stop
time 23.23
10 = 1 s / 1000 = 1 s Emergency stop Off3 deceleration time. 0.000 ... 1800.000 s
Inactive / uint32 Selects a source that forces the speed reference to zero
just before it enters the ramp function.
0 = Force speed reference to zero before the ramp
function
1 = Speed reference continues towards the ramp
function as normal Speed ramp in zero
