10. 3. 3. 9. NXP00002V165
• Hardware compatible with VB00251G and VB00561F or newer.
• Bug fix: Encoder fault F41_S9 is given if trying to start PM-motor without the
encoder identification done if absolute encoder or resolver used.
• Bug Fix: If control have been connected to 690V power unit, and the control is after
that connected only to +24V: F2_S2 possible for no reason.
• Bug fix: If two or more warning or autoreset fault at the same time and one is
reseted then other warning/fault text is wrong.
• Bug fix: If Start Function in autoreset fault is different than normal StartFunction
then autoreset Start Function was not selected in every situation.
10. 3. 3. 10. NXP00002V166
Replaced version: NXP00002V165.VCN
Changes in system software:
• Revision 165 did not support ready-state when evacuation mode (special applica-
tions) and low dc-bus voltage.
• Frequency limit conditions of the stall protection function was not active in revision
165 but protection was active through whole frequency area.
• When downloading parameters from panel and the parameter value is not within
the allowed max. / min. range of unit, the parameter is set to default value.
Changes in applications:
• All applications: If one reset input was active, the unit did not accept reset from
other source. (For instance when I/O terminal reset was high, reset via Profibus was
not possible).
• Local/Remote control: When mode 0 was selected to Place A Start/Stop logic
(P2.2.1), the Reverse input did not work. Corrected.
• Local/Remote control: Reading of analogue inputs did not work when corresponding
input filtering time was set down to 10 ms. Corrected.
• Multipurpose (ASFIFF06V311): When Motor Potentiometer function with no reset
was used and max. frequency + motor potentiometer reference were over 50 Hz
when power was switched on, the frequency did not rise above 50 Hz. Corrected.
• Pump and fan control: DC braking parameter P2.2.6.15 can be now changed when
unit is running.
• Multipurpose (APFIFF06V108): When fieldbus reference scalings (Parameters 2.91
& 2.92) were used, the unit was able to run frequencies under set minimum fre-
quency in case fieldbus reference was under set min. freq.
• Multipurpose (APFIFF06V108): When closed loop drive was controlled by Profibus
and stop 1 (bit # / 0 / by ramp) was used, the unit was remaining to run 0 speed if
torque on motor shaft was requested = actual output frequency 0<f<0. Corrected
so that stop status is accepted when FreqRampOut goes down to 0 instead of copar-
ing to the value of the actual frequency. (When controlled by Profibus, the control
word bit # 3 is preferred to use for start/stop purpose, due then stop mode are fol-
