How to Programme the Frequ...
3-16 Reference 2 Source
Option: Function:
Select the reference input to be used
for the second reference signal.
par. 3-15 Reference 1 Source,
par. 3-16 Reference 2 Source and
par. 3-17 Reference 3 Source define up
to three different reference signals.
The sum of these reference signals
defines the actual reference.
This parameter cannot be adjusted
while the motor is running.

3-19 Jog Speed [RPM]
Range: Function:
Application [Application Enter a value for the jog speed n
dependent dependant] which is a fixed output speed. The
*
frequency converter runs at this
speed when the jog function is activa-
ted. The maximum limit is defined in
par. .
See also par. 3-80 Jog Ramp Time.
3-41 Ramp 1 Ramp Up Time
Range: Function:
Application [Applica- Enter the ramp-up time, i.e. the
dependent tion acceleration time from 0 RPM to
*
dependant] par. 1-25 Motor Nominal Speed. Choose
a ramp-up time such that the output
current does not exceed the current
limit in par. 4-18 Current Limit during
ramping. See ramp-down time in
par. 3-42 Ramp 1 Ramp Down Time.

3-42 Ramp 1 Ramp Down Time
Range: Function:
Application [Applica- Enter the ramp-down time, i.e. the
depend- tion deceleration time from par. 1-25 Motor
ent dependant] Nominal Speed to 0 RPM. Choose a
*
ramp-down time such that no over-
voltage arises in the inverter due to
regenerative operation of the motor,
and such that the generated current
does not exceed the current limit set in
par. 4-18 Current Limit. See ramp-up
time in par. 3-41 Ramp 1 Ramp Up
Time.

4-10 Motor Speed Direction
Option: Function:
Selects the motor speed direction required.
Use this parameter to prevent unwanted
reversing.
[0] Clockwise Only operation in clockwise direction will be
allowed.
[2] Both directions Operation in both clockwise and anti-
*
clockwise direction will be allowed.
NOTE
The setting in par. 4-10 Motor Speed Direction has impact
on the Flying Start in par. 1-73 Flying Start.
4-11 Motor Speed Low Limit [RPM]
Range: Function:
Application [Application Enter the minimum limit for motor
dependent dependant] speed. The Motor Speed Low Limit
*
can be set to correspond to the
manufacturer's recommended
minimum motor speed. The Motor
Speed Low Limit must not exceed
the setting in par. 4-13 Motor Speed
High Limit [RPM].
4-12 Motor Speed Low Limit [Hz]
Range: Function:
Application [Application Enter the minimum limit for motor
dependent dependant] speed. The Motor Speed Low Limit
*
can be set to correspond to the
minimum output frequency of the
motor shaft. The Speed Low Limit
must not exceed the setting in
par. 4-14 Motor Speed High Limit [Hz].
