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.
