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.
Example:
Terminal Freeze ref./
(16) (17) Freeze output
No speed change 0 0 1
Speed down 0 1 1
Speed up 1 0 1
Speed down 1 1 1
The speed reference frozen via the control panel
can be changed even if the frequency converter
has stopped. The frozen ref
erence 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 b
een set to Multi S etup.
Choice of Setup M
SB/Speed up and choice
of Setup LSB/Speed down - In conjunction
with Freeze reference or Freeze output -enable
up/down spee
d change.
The selecti
on of Setup changes in accordance
with the below table:
Selection of Setup Freeze ref/
(32)msb (33)lsb Freeze output
Setup 1 0 0 0
Setup 2 0 1 0
Setup 3 1 0 0
Setup 4 1 1 0
No speed change 0 0 1
Speed down 0 1 1
Speed up 1 0 1
Speed down 1 1 1
Catch-up/Slow-down is selected if the reference
value is to be increased or reduced by a programmable
percentage value set in parameter 219.
Slow-down Catch-up
Unchanged speed 0 0
Reduced by %-value 1 0
Increased by %-value 0 1
Reduced by %-value 1 1
Ramp 2 is selected if a change between ramp 1
(parameters 207-208) and ramp 2 (209-210) is desired.
Logic ’0’ ⇒ ramp 1, while logic ’1’ ⇒ ramp 2.
Mains failure inverted is to be selected if parameter
407 Mai n s failure and/or parameter 408 Quick
discharge is activated. Mains failure inverted is
active in the logical ‘0’ situation.
NB!:
The frequency converter can be totally
damaged by repeating the Quick discharge
function on the digital input with mains
voltage connected to the drive.
Pulse reference is selected if a pulse sequence
(speed) of 0 rpm is used, corresponding to Ref

parameter 204. The frequency is set in parameter
