Pr75
Pr76 Position Reference using
Serial Communications R–W
16384 steps/rev
Def
.
val.
0 Res.
These two parameters permit serial communications
to be used to control the position reference
.
The
position reference value is [( Pr76
×
1000) + Pr75 ]
.
Any changes to the values of Pr75 and Pr76 are
effective only after the values of both parameters
have been written.
Pr80 I

t Level
RO
0 to 100 %
Def .
val.
Res. 0.1
Displays values corresponding to I
2
t accumulation .
I
2
t limit is activated at 100%.
Pr81 Braking resistor protection RO
0 to 1999.9
Def
.
val.
Res. 0.1
Displays a value proportional to the power
dissipated in the braking circuit
. When Pr81
reaches 100, parameter b95 is set at 1.
Pr83 Rotor position
RO
0 to 2047
Def
.
val.
Res. 1
Shows the shaft position at all times.
Pr95 Number of Motor Poles R–W
Def
.
val.
6 Res.
4, 6, or 8 poles can be set.
Pr97 Software version number RO
Def
.
val.
Res.
(This manual applies to V4.XX.XX software.)
Pr98 Last alarm store RO
Def .
val.
Res.
Displays the cause of the last trip
.
Pr98 is cleared
when the Drive is reset by setting b03 at 1
.
When
Pr98 is interrogated using Serial Communications, a
number representing the trip is transmitted . The
numbers are as follows:
No. Condition Trip code
0 Drive normal
1 Overvoltage OV
2 Undervoltage OU
3 Overcurrent OC
4 Overtemperature Oh
5 Resolver break rb
6 I

11.2 Bit parameters
b0 Enable change of security code R–W
0 or 1
Def
.
val.
0 Res.
Set at 1 to enable the security code to be changed
to any valid number
.
Refer to Pr25 .
b1 Recall last parameter settings
from
EEPROM
R–W
0 or 1 Def .
val.
0 Res.
Return to the last-written parameter values
.
Set b2
at 0 to allow parameter recall . The display will show
rEAd
during this process. Related to
b5
and
b99
.
b2 Drive enable
R–W
0 or 1
Def
.
val.
1 Res.
When b2 = 0, the Drive is disabled.
When
b2
= 1, the Drive is enabled .
Refer to terminal B14.
