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

RO
0 to 100 %
Def
.
val.
Res. 0.1
Displays values corresponding to I

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

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.
