Parameter Description
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.

NOTE
This parameter cannot be adjusted while the motor is
running.
3-19 Jog Speed [RPM]
Range: Function:
Size [ 0 - par. Enter a value for the jog speed n
related 4-13 RPM]
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 4-13 Motor
Speed High Limit [RPM].
