selected. A logic ‘1‘ on the terminal selected for speed
up, the reference or the output speed will increase.
A logic ‘1‘ on the terminal selected for speed down, the
reference or the output frequency will be reduced.
Pulses (logic ‘1‘ minimum high for 3 ms and a
minimum pause of 3 ms) will change the speed of
0.1% (reference) or 1 rpm (output speed).
If
Speed up/Speed down
is activated for more than 400
msec., a continuous change using ramp 2 will begin.

The speed reference frozen via the control panel
can be changed even if the frequency converter
has stopped. The frozen reference will be stored
in case of a mains cut-out.
Choice of Setup LSB and MSB
enables one of the
four Setups; however, this depends on the fact that
parameter 004 has been set to
Multi Setup
.
Choice of Setup MSB/Speed up and choice
of Setup LSB/Speed down
- In conjunction
with
Freeze reference
or
Freeze output
- enable
up/down speed change.
The selection of Setup changes in accordance

NB!:
The frequency converter can be totally
damaged by repeating the Quick discharge
