During any state: idle, start, run or brake, if the red LED stays on along with the brake of the
motor, this indicates a fault condition. A fault condition is due to one of the following
conditions:
●
●
●
●
●
Blinking of the red LED during the running of the motor indicates that software current
limitation is in action.
Changing real-time parameters
The real-time parameters can be changed using the potentiometers of the control board.
Table 16
Potentiometer functionality based on open/closed loop driving strategy
If during the configuration using GUI, the "from RV1" control has been unchecked, the
value of duty cycle (or the value of current reference) is not set by P1, but has a fixed value.
If during the configuration using GUI, the "From RV2 - RV3" control has been unchecked,
the value of the rising delay coefficient and the value of the falling delay coefficient are not
set by P2 and P3, but have fixed values.
Hardware overcurrent: current flowing inside motor reaches a value greater than max
current allowed 4.1 amp (see
by
Over voltage: bus voltage reaches a value greater than 280 Vac.
Over temperature: onboard temperature sensor measures a temperature greater than
60°.
Startup failed: startup phase ends without getting a sufficient number of valid zero
crossing events.
Motor stalled: during the run of the motor no other zero crossing events have been
observed.
