If asynchronous motor is selected, enter
acceleration time from 0 Hz to
parameter 1-23 Motor Frequency
. If PM
motor is selected, enter acceleration time
from 0 RPM to
. Select a ramp-up time such
that the output current does not exceed
the current limit in
parameter 4-18 Current
Limit
during ramping up.

Enter deceleration time from
parameter 1-25 Motor Nominal Speed
to
0 RPM. Select a ramp-down time such
that the output current does not exceed
the current limit in
parameter 4-18 Current Limit
during
ramping down.

*
[0.05
- 3600
s]
Enter the jog ramp time, which is the
acceleration/deceleration time between 0 Hz
to
parameter 1-23 Motor Frequency
. Ensure
that the resulting output current required for
the given jog ramp time does not exceed the
current limit in
parameter 4-18 Current Limit
.
The jog ramp time starts after activation of a
jog signal via the control panel, a selected
digital input, or the serial communication
port.
3-81 Quick Stop Ramp Time
Range:

*
[0.05 -
3600 s]
Enter the quick stop ramp time from the
parameter 1-23 Motor Frequency
to 0 Hz.
During ramping, no overvoltage may occur
in the inverter, nor may the generated
current exceed the limit in
parameter 4-18 Current Limit
. Quick stop is
activated with a signal on a selected digital
input or via the serial communication port.
3-85 Check Valve Ramp Time
Range:
Function:
0 s
*
[0 -
60 s]
To protect ball check valves in a stop situation, the
check valve ramp can be utilized as a speed down
ramp rate. Set the ramp rate from
parameter 4-11 Motor Speed Low Limit [RPM]
or
parameter 4-12 Motor Speed Low Limit [Hz]
to check
valve ramp end speed, set in
parameter 3–86 Check
Valve Ramp End Speed [RPM]
or
parameter 3–
87 Check Valve Ramp End Speed [HZ]
. When
parameter 3–85 Check Valve Ramp Time
is different
from 0 s, the check valve ramp time is effectuated
and is used to ramp down the speed from motor
speed low limit to the check valve end speed in
parameter 3–86 Check Valve Ramp End Speed [RPM]
or
parameter 3–87 Check Valve Ramp End Speed
[HZ]
