3-17 Reference 3 Source
Option: Function:
Select the reference input to be used
for the third reference signal.
3-15 Reference 1 Source , 3-16 Reference
2 Source and 3-17 Reference 3 Source
define up to three different reference
signals. The sum of these reference
signals defines the actual reference.

which is a fixed output speed. The
frequency converter runs at this speed
when the jog function is activated. The
maximum limit is defined in

acceleration time from 0 RPM to
1-25 Motor Nominal Speed . Choose a
ramp-up time such that the output
current does not exceed the current
limit in
4-18 Current Limit during
ramping. See ramp-down time in

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
