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
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 / 500000 (frequency/direction signal)
if b42.5=1 Pr7 = Fin
⋅
Pr4 / 125000 (quadrature signal)
where Fin is the frequency on the encoder input.
Pr5
Internal reference
.
Unit=rpm, range=±9000, default=0. If b40.12=1 and b40.13=0, Pr7 will
be the same as 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 used as
a reference for the speed control loop. In certain operating modes Pr7 can be used as a
reference for other factors (torque / acceleration). In this case Pr7 is expressed in a suitable
unit.
Pr8
Acceleration ramp for positive speed values
.
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 acceleration of 1000 rpm takes Pr8
seconds.
Pr9
Deceleration ramp for positive speed values
.
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 deceleration of 1000 rpm takes Pr9
seconds.
Pr10
Acceleration ramp for negative speed values
.
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 acceleration of 1000 rpm takes
Pr10 seconds.
Pr11
Deceleration ramp for negative speed values
.
Unit=s/krpm, range=0.002..65.535,
resolution=0.001 s, default=0.002 s. Deceleration for negative speeds required of the motor
by way of the speed reference is internally limited so that deceleration of 1000 rpm takes
Pr11 seconds.
