9.4.4 Profile mode and analog inputs
Parameter P 301[0] - CON_REF_Mode determines whether the reference values
are processed via the profile generator (setting “PG(0)”) or directly (setting “IP(1)”). If
direct input via IP mode is selected, only the input filters are active. The analog
values are scanned and filtered in the torque control cycle and then directly
transferred as references for the speed or torque control.
CAUTION!
Your system/motor may be damaged if put into operation in
an uncontrolled or inappropriate manner.
Improper conduct can cause damage to your system /
machine.
l
Before the “Start” step, make absolutely sure that a valid
setpoint has been entered, as the configured setpoint
will be immediately transmitted to the motor after the
motor control function starts, which may result in the
motor accelerating unexpectedly.
NOTE
l
If the analog inputs are used as feedback for control circuits, they
will be sampled every 125 µs.
l
If functions are assigned to the analog inputs using
P 109
[0]/P 110[0]
, the inputs will be sampled every 1 ms.
l
By switching parameter
P 301[0] - CON_REF_Mode
from PG(0)
to IP(1) mode, an analog input can be used as a "fast input" (e.g.
Touch probe). The sampling time set in
P 306[0] - CON_IpRefTS
for the interpolation takes effect.

9.4.5 Wire Break Monitoring
P 399 - CON_ANA_WireBrk_Th is used to define the wire break monitoring
threshold (in V) (parameter index [0] for ISA00, parameter index [1] for ISA01). If the
voltage falls below this limit an error message is generated. The error response can
be configured using P 30[52] - Reac_Ana (see Section "Error reactions" on page
325).
