3.3 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
Analog 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 in the scale ± 10 V.
Pr2
First full scale of analog 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 analog input.
Pr3
Second full scale of analog 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 analog input.
When Pb94.3 is 1, Pr3 becomes the speed of the virtual axis.
Pr4
Frequency reference full scale
(connector X5). 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/sign signals)
if b42.5=1 Pr7 = Fin
⋅
Pr4 / 500000 (quadrature signals)
where Fin is the encoder input frequency.
Pr5
Internal reference.
Unit=rpm, range=±9000, default=0. If b40.12=1 and b40.13=0
Pr7 will be identical to Pr5.
Pr6
Reserved read-only speed reference
. Unit=rpm, range=±9000. If b40.2=1 Pr6 is
only utilised as a speed reference for the control loop. The active operating mode will
enter its speed request in parameter Pr6.
Pr7
Main reference
(read-only parameter). Unit=rpm, range=±9000. If b40.2=0 Pr7 is
utilised as a reference for the speed control loop. In some operating modes Pr7 can be
used as a reference for other factors (torque/acceleration). In these cases Pr7 is
expressed in the most suitable unit.
Pr8
Positive speed acceleration ramp
. Unit=s/krpm, range=0.002...65.535,
resolution=0.001 s, default=0.002 s. Acceleration for positive speeds required of the
motor by way of the speed reference is internally limited so that a speed change of
1000 rpm takes Pr8 seconds.
Pr9
Positive speed deceleration ramp
. Unit=s/krpm, range=0.002...65.535,
resolution=0.001 s, default=0.002 s. Deceleration for positive speeds required of the
motor by way of the speed reference is internally limited so that a speed change of
1000 rpm takes Pr9 seconds.
Pr10
Negative speed acceleration ramp
. Unit=s/krpm, range=0.002...65.535,
resolution=0.001 s, default=0.002 s. Acceleration for negative speeds required of the
motor by way of the speed reference is internally limited so that a speed change of
1000 rpm takes Pr10 seconds.
Pr11
Negative speed deceleration ramp
. Unit=s/krpm, range=0.002...65.535,
resolution=0.001 s, default=0.002 s. Deceleration for negative speeds requested of
the motor by way of the speed reference is internally limited so that a speed change
of 1000 rpm takes Pr11 seconds.
