If
Hold Zero Frequency
(06.008) = 0 the sequencer state machine goes to the DISABLE state and the inverter is disabled when the Final drive run is de-activated and the motor reaches
standstill.
If
Hold Zero Frequency
(06.008) = 1 and
Motor Pre-heat Current Magnitude
(06.052) = 0% the sequencer state machine goes to the STOP state when the Final drive run is de-activated and the
motor reaches standstill. The drive remains enabled with a frequency reference of zero. If
Motor Pre-heat Current Magnitude
(06.052) is set to a non-zero value it defines the current in the
motor when the sequencer state machine is in the STOP state. This is intended for applications where there is no motor load at standstill, but motor current is required to prevent condensation
in the motor when it is stopped. If the motor is not force cooled the motor cooling is less effective at standstill than when the motor is rotating, and so care should be taken not to damage the
motor by leaving it at standstill for prolonged periods with a high level of current.
When in HEAT mode i.e.
Motor Pre-heat Current Magnitude
(06.052) is a non-zero value, the current used is a percentage of the motor rated current.

If
Catch A Spinning Motor
(06.009) = 0 the
Post Ramp Reference
(02.001) is set to zero when the drive is started. This is suitable for applications where the motor is at standstill or rotating at a
low speed when the drive is enabled.
If
Catch A Spinning Motor
(06.009) > 0 a test is carried out to measure the frequency of the motor when the sequencer state machine enters the RUN state. The minimum time for the test is
approximately 250ms, but this may be extended as time is allowed for the motor flux to build up based on the setting of the motor parameters including
Motor Rated Speed
(05.008) which
should be set to approximately the correct value. The measured frequency is used to preset the
Post Ramp Reference
(02.001) and give a smooth start even if the motor is already spinning.
The test is not carried out if the Final drive run is activated when the sequencer state machine is in the STOP state or if a stator resistance measurement is carried out when the drive is enabled
(see
Open-loop Voltage Mode
(05.014)). For the test to be successful it is important that the motor parameters, especially the
Stator Resistance
(05.017), are set up correctly even if fixed boost
mode is selected with
Open-loop Voltage Mode
(05.014). For larger motors it may also be necessary for
Spin Start Boost
(05.040) to be increased from its default value of 1.0.
Restrictions can be placed on the direction of movement and the possible direction of the detected frequency as given in the table below.
