Function:
[0.05 Enter acceleration time from 0 Hz to
1-23 Motor Frequency if Asynchronous
motor is selected. Enter acceleration time
from 0 RPM to 1-25 Motor Nominal Speed if
PM motor is selected. Select a ramp-down
time such that the output current does not
exceed the current limit in 4-18 Current
Limit during ramping. See ramp-down time
in 3-52 Ramp 2 Ramp Down Time.
Function:
[0.05 Enter deceleration time from 1-23 Motor
Frequency to 0 Hz if Asynchronous motor is
selected. Enter deceleration time from
1-25 Motor Nominal Speed to 0 RPM if PM
motor is selected. Select a ramp-down time
such that the output current does not
exceed the current limit in 4-18 Current
Limit during ramping. See ramp-up time in
3-51 Ramp 2 Ramp Up Time.
Function:
Enter the jog ramp time, i.e. the
acceleration/deceleration time between 0 Hz
to 1-23 Motor Frequency. Ensure that the
resultant output current required for the
given jog ramp time does not exceed the
current limit in 4-18 Current Limit. The jog
ramp time starts upon activation of a jog
signal via the control panel, a selected
digital input, or the serial communication
port.
Function:
[0.05 - Enter the quick stop ramp time from the
1-23 Motor Frequency to 0 Hz. During
ramping, no over-voltage may arise in the
inverter, nor may the generated current
exceed the limit in 4-18 Current Limit is
activated by means of a signal on a
selected digital input or via the serial
communication port.
