Binary parameters
The binary parameter Pb40 can be read and set and then stored. The binary parameter Pb41
provides indications about the status of the system. The parameters Pb42 and Pb99 be read
and set and then stored.
Par. Descrption
Field
Def.
b39.0
Undervoltage in continuous current.
b39.0=1 When the drive is
supplied in continuous voltage, this bit permits the control of the
undervoltage alarm.
b39.2
(1) if feedback supply actives.
b39.9
(1) If fine phasing on encoder zero point dog is activated.
b39.15
CAN: encoder receive watchdog
. (see par. “
encoder CAN
”).
b40.0
Selection of the first or second full scale of the speed reference.
If
= 0, Pr2 will be used to rate the analogue reference. If = 1, parameter
Pr3 will be used..
R/W
M
0
b40.1
Activation of the algorithm to suppress vibration at 0 speed.
If =
1, the algorithm is turned on.
R/W
M
0
b40.2
Selection of the reserved/user reference.
If = 1, the reserved
reference of the operating mode in use is used. If = 0, the reference
selected by b40.0, b40.12 and b40.13 is used.
R/W
M
0
b40.3
Reference hold.
If = 1, the reference will not be updated and the
motor will not follow the variations of the input reference. If = 0, the
reference will follow the variation of the input reference
R/W
M
0
b40.4
Left limit switch.
If = 1 and the reference selected requires negative
speed, the reference is set to 0 following the ramp set in Pr12. If = 0,
no control is made.
R/W
M
0
b40.5
Right limit switch.
If = 1 and the reference selected requires
negative speed, the reference is set to 0 following the ramp set in
Pr12. If = 0, no control is made.
R/W
M
0
b40.6
Stop function.
If = 1, the motor is set to zero speed following the
ramp set in Pr12.
R/W
M
0
b40.7
Selection of the absolute/relative speed window.
If = 0, the speed
window Pr14 Pr15 b41.1 will function in relative mode. Otherwise,
if = 1, it will function in absolute mode.
R/W
M
0
b40.8
Analogue torque limit.
If = 1, Pr22 will be used and also the
auxiliary analogue input in order to limit the torque to the motor.
The sign of voltage at aux. differential analog input doesn’t interest.
R/W
M
0
b40.9
Software enable.
If = 0, the converter cannot be enabled.
R/W
M
1
b40.10
Enable low voltage supply.
Activates low voltage management
(from 40 to 180V~, and from 57Vdc to 255Vdc), so the maximum
speed of the axis is lower.
W 0
b40.11
Injection of third harmonic in modulation.
W 0
b40.12
Selection of the digital/analogue reference.
If = 0, the analogue
input will be selected as the main reference. If = 1, the reference will
be digital and b40.13 can be used to select parameter Pr4 or
parameter Pr5.
