current and can be used to limit the torque and the rise in motor temperature.
Switching between the two current limits is enabled via a logic input or via the
Modbus serial link.
Automatic DC injection
This function enables standstill DC injection, which can be set between 0 and
1.2 times the value of the nominal drive current (factory-set configuration:
0.7 x motor nominal current), as soon as operation is no longer controlled and
the motor speed is zero:
v Either for a period of time, which can be set between 0.1 and 30 s
v Or continuously
Factory-set configuration: Function active with DC injection for 0.5 s.
In 3-wire control, DC injection is only active if logic output LI1 is active
(assigned to stop).
Motor control profiles
Three motor control profiles are available depending on the application
requirements:
v Standard (U/F): Simple motor control profile maintaining a constant voltage/
frequency ratio with an optional low speed setting.
Profile suitable for small conveyors, applications with motors connected in
parallel, etc.
v Performance (sensorless flux vector control): Profile which can guarantee the
level of performance with a motor with the same power or one rating less. This profile
can be used to obtain improved dynamic specifications at low speed.
Profile suitable for running machines, etc.
v Pump/Fan (Kn²): Quadratic ratio for obtaining a torque proportional to the square
of the speed. This profile can be used to optimize energy consumption according to
the load applied to the machine.
Profile suitable for pump regulation, air extraction, etc.
Switching frequency, noise reduction
The switching frequency setting between 2 and 16 kHz permits a reduction in the
noise generated by the motor for any application requiring a low level of noise.
The switching frequency can be modulated randomly in order to avoid resonance.
This function can be disabled if it causes instability.
Switching the DC voltage at high frequency is useful for supplying the motor with a
current wave having little harmonic distortion.
This type of operation increases drive overheating.
Factory-set configuration: Low frequency set at 4 kHz.
Frequency jump
Used to pass a mechanical resonance point likely to cause increased noise or risk of
mechanical breakdown.
The frequency jump is fixed. It is within ± 1 Hz of the configured resonance point.
Jog mode
This can be used for pulse operation with minimum ramp times (0.1 s), a fixed speed
reference set at 5 Hz and minimum time of 0.5 s between 2 pulses.
Enabled by 1 logic input and pulses issued by the operating direction command.
This function is suitable for machines with product insertion in manual mode (for
example, gradual movement of the mechanism during maintenance operations).
