frequency inverter setup.
ABB ACH 550
If Multibox III is used, set control mode to
”AUTO”.
”LOC” = Control using front panel.
”AUTO” = External PID control.

Operation limits
2003 Max current
Setup the max allowed current. In many cases this is the same
as indicated on the motor nameplate. For example 2,6A
2007 Minimum freq
Setup minimum allowed frequency. Set at 15Hz. If set lower,
both fan and inverter may suffer damage.
2008 Maximum freq
Set maximum frequency.
Set maximum allowed frequency for the selected fan.
9905 Motor nom volt
9906 Motor nom curr
9907 Motor nom freq
9908 Motor nom speed
9909 Motor nom power
Setup the motor´s rated voltage as indicated on the motor
nameplate. For exampel 400V
Setup the motor´s rated current as indicated on the motor
nameplate. For exampel 2,6A
Setup the motor´s rated frequency as indicated on the motor
nameplate. For exampel 50Hz
Setup the motor´s rated speed as indicated on the motor
nameplate. For exampel 2830 rpm
Setup the motor´s rated power comsumption as indicated on
the motor nameplate. For exampel 4Kw

Setup ramp up time. Normally 20 seconds. 2202 Acceler time 1
2203 Deceler time 1
Ramp time setup.
Setup max reference
1105 Ref1 Max
Setup the value(Hz) of max reference voltage(10V). If you set the
parameter 2008 to ex. 55Hz then set this parameter to 55Hz too.
This is a quick guide for setting up the frequency inverter with the minimu required settings.
These settings apply to a typical Geovent product constellation, and are not directly applicable for use with other products.
For settings of other parameters/macros and detailed explanation hereof, see the instructions manual from ABB.
Setup start condition1. if set to ”disable” the drive ignores DI4
as a start condition. If set to anything else the drive will not
start.
Setup start conditions
1608 Enable1
(Ramp time correlates with fan size –larger fan = more ramp time)
Setup ramp down time. Normally 50 seconds.
(Ramp time correlates with fan size –larger fan = more ramp time)
(If you do not set this parameter the fan will not go above 50Hz)
