Pr19 Peak
current
. Unit=%, range=0..100.0%, resolution=0.1%, default=100.0%.
Maximum current that the drive can deliver to the motor expressed as a percentage of
drive peak current. It is good practice to maintain this value to within 3 times the
rated motor current.
Pr20
DC bus voltage
. Unit=volt, read-only parameter. Shows the value of DC bus
voltage.
Pr21 Torque
limiter
, read-only parameter. Unit=%. Can be used by operating modes to
restrict motor torque.
Pr22 Auxiliary analogue reference
. Unit=%. The displayed value will be
Pr22=Vin
⋅
100/9.76. Resolution is 0.2%.
Pr23 Alarm
code
. This code shows the currently active alarm; zero means that no alarms
are active. Consult the table of alarm codes for more details.
Pr24 Last
alarm
. This parameter stores the last alarm. Pr24 is reset when the alarm reset
command is entered (b99.10).

Pr25
Code describing installed software version
. Read-only parameter.
Pr26 Serial line baud-rate code
. Default=8. This is the code for programming
transmission speed. For more information consult the section on the serial interface.
Pr27
Serial line address code
. Default=0, possible settings=0..31. For more information
consult the relative section of the manual.
Pr28
Motor shaft position
. Unit=steps, range=0..4095. Read-only parameter that shows
the absolute position of the resolver.
Pr29
Number of motor poles
. Possible settings=2..64, default=8.
Pr30
Resolver position offset
. Default=0; use Pr30 for electronic correction of the
mechanical resolver position.
Pr31 Operating
mode
. Default=0. Use Pr31 to select the active operating mode. 0
indicates no operating mode.
Pr32 Rated
speed
. Unit=rpm, range=0..9000, default=3200. Nominal motor speed.
Should be programmed with the motor speed at which rated voltage corresponds to
drive power feeding voltage reduced by 13%. Consult the formula in section
Commissioning the HPD drive
.
