Two standard analog inputs (ISA00, ISA01) are available. These inputs can be
configured...
with negative values for
analog
setpoint settings
with positive values for
digital
setpoint processing
in the “Function selection of analog inputs” screen (see Section "Analog inputs" on
page 2
) P 109[0] - MPRO_INPUT_FS_ISA00 and P 110[0] - MPRO_INPUT_
FS_ISA01. By using the "REV(-2) = Analog setpoint" setting, an analog input voltage of
±10 V can be processed as a setpoint.
10 V correspond to
This parameter (P 173 - MPRO_ANA0_Scale for ISA00, P 183 - MPRO_ANA1_Scale
for ISA01) is used to define which speed / which torque / which position corresponds
to the maximum analog value. Depending on the control mode being used (see
Section "Basic settings" on page 107), the value will be stored in parameter index [0]
(torque control), [1] (speed control) or [2] (position control).
Offset (O)
This parameter (P 174 - MPRO_ANA0_SOffset for ISA00, P 184 - MPRO_ANA1_
SOffset for ISA01) compensates for component variations and is used for offset
compensation purposes. Depending on the control mode being used (see Section
"Basic settings" on page 107), the value will be stored in parameter index [0] (torque
control), [1] (speed control) or [2] (position control).
Backlash (B)
This parameter (P 175 - MPRO_ANA0_SThreshold for ISA00, P 185 - MPRO_
ANA1_SThreshold for ISA01) can suppress axis motion close to the standstill (stop)
position. Depending on the control mode being used (see Section "Basic settings" on
page 107), the value will be stored in parameter index [0] (torque control), [1] (speed
control) or [2] (position control).
