Description
1.9
>I/O
-
It includes the setting and the status of the digital
I/O and of the analog output.
1.9.1
OUT BACKUP
2
It defines the behaviour of the power digital outputs
when the mains power is absent.
0 = In case of lack of the mains power, the output
status is set to 0 (output OFF).
1 = In case of lack of the mains power, the output
status is maintained.
This function allows setting the power digital outputs
in power saving mode, which is very useful for the
backup batteries.
1.9.2
OUT TYPE
2
In this section, it is possible to select the type of
analogue output. In fact, the connector features one
output only: this parameter defines whether the
user will use current output (4-20mA) or voltage
output (0-10V). If you set current output, the
voltage value will display a calibration error. The
same problem will occur in case you set voltage
output: the current output value will display a
calibration error.
1.9.3
SET OUT
2
It sets the size unit to be transferred to the
analogue output:
SERCOS: the output value is cyclically sent by the
control unit of the SERCOS interface. For this
setting, the active controller must be “SERCOS”.
IQ: Direct current reference (active component of
the current vector).
VEL: Motor current speed reference.
ABS-VEL: Reference of the absolute value of the
motor current speed.
ERR-VEL: Speed error: this is the difference between
the motor actual speed and the preset speed.
ERR-POS: Position error: this is the difference
between the motor actual position and the preset
position.
1.9.4
OFFSET [V]
2
See next parameter “OFFSET [mA]”.
