Function:
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:
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. Choose 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 overvoltage 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.
