30 
Pr33  Rated current that can be delivered by the drive (can be maintained indefinitely) 
expressed in percent of the peak rated current of the drive. 
Pr35  Instantaneous current requested by the motor expressed as a percentage of drive peak 
rated current. 
b99  Bit parameter for the fundamental orders. 
 
Using extended menu you can manage all parameters and pico-PLC instructions. 
 
Restoring default parameters 
 
If you need to restore the factory-set default parameter values: 
-  disable the drive via hardware (open terminal 11 on board X3) 
-  power-up the system 
-
 the display will show “IdLE” after approximately 3 seconds 
-  set b99.7 and b99.13 to zero 
- enter command b99.12 
-  save your changes with b99.14 and b99.15. 
 
4.3. Basic parameters 
 
To access all the following parameters open the extended menu by setting b99.6 to one. 
For this procedure, b99.7 must be set to zero. 
 
DECIMAL PARAMETERS 
 
Pr0 Motor speed: this is a read-only parameter expressed in rpm;  the message Pr0 never 
appears on the display. In its place a message corresponding to drive status is shown. 
Pr1  Analogue reference offset. This is expressed in input A/D converter counts. 
Programming limits are -10000 and +10000 while the range of the A/D converter is 
from -16384 to  +16383 over ± 10 V. 
Pr2  First full scale of analogue reference. Unit=rpm, range=±10000, default=3000. If 
b40.0=0  and  b40.12=0, Pr7 will be equal to: Vin ⋅ Pr2 / 9.76 where Vin is the 
voltage on the analogue input.
 
Pr3  Second full scale of analogue reference
. Unit=rpm, range=±10000, default=-3000. 
If b40.0=1  and  b40.12=0, Pr7 will be equal to: Vin ⋅ Pr3 / 9.76 where Vin is the 
voltage on the analogue input. 
Pr4  Frequency reference full scale (connector X6). Unit=rpm, range=±32767, 
default=3000. If b40.12=1  and  b40.13=1, Pr7 will have the following value: 
  if b42.5=0       Pr7 = Fin ⋅ Pr4 / 2000000     (frequency/direction signal) 
  if b42.5=1       Pr7 = Fin ⋅ Pr4 / 500000      (quadrature signal) 
  where Fin is the frequency on the encoder input.
