SKIP FREQUENCY
Skip Frequency (#1, #2 and #3) The center frequency of the frequency band to skip
or treat as a speed command dead-band.
Skip Band (#1, #2 and #3) The width of the band centered about the Skip Frequency.
For example, if Skip Frequency #1 is set to 20Hz and Skip Band #1 is set to 5Hz,
continuous operation is not allowed in the dead-band of 15Hz to 25Hz.
Note: Three bands can be defined independently or the three values can be
selected to skip one wide frequency band.
SYNCHRO STARTS
Sync Start Enable Allows Synchro Starts.
Sync Scan V/F Sets the Volts/Hertz ratio for the Synchro Starts feature as a
percentage of the V/Hz ratio defined by the Max Output Volts/Base Frequency.
This Sync Scan V/F percentage value is multiplied by the Max Output Volts/Base
Frequency value. If this value is too high, the inverter may fault on Over-Current.
Sync Setup Time The time for the inverter to ramp the output voltage from zero to
the voltage that corresponds to the frequency set by the “Sync at Max Freq”
parameter. A 0.5 second delay before the ramp begins is not included in this
time. If the Synchro Starts feature is not operating quickly enough, decrease the
Sync Setup Time value.
Sync Scan Time The time allowed for Synchro Starts to scan and detect rotor
frequency. Generally, the shorter the Sync Scan Time the more likely a false
Synchro Starts will be detected. This value should be set high enough to
eliminate false Synchro Starts.
