h
: polarity
The algebraic sign of the position and speed values of the motor controller can be set with
the corresponding polarity_flag. This can serve to invert the motor's direction of rotation
with the same nominal values.
In most applications, it makes sense to set the
position_polarity_flag
and the
velocity_polarity_flag
to the same value.
Setting of the polarity_flag influences only parameters when reading and writing.
Parameters already present in the motor controller are not changed.

Final stage parameters
6.4.1
Overview
The mains voltage is fed into the final stage via a pre-charged switch. When the power
supply is switched on, the switch-on current is limited and charging is monitored. After
pre-charging of the intermediate circuit, the charging switch is bypassed. This condition is
a prerequisite for controller enable. The rectified mains voltage is smoothed out by the
capacitors of the intermediate circuit. From the intermediate circuit, the motor is fed via
the IGBTs. The final stage contains a series of safety functions, some of which can be
parameterised:
Controller enable logic (software and hardware release)
Excess current monitoring
Excess voltage / under-voltage monitoring of the intermediate circuit
Power section monitoring
