It defines the calculating relationship between the final setting frequency and the master/auxiliary
freqeuency.
0:
Master s auxiliary setting.
1:
Master setting − auxiliary setting.
2: MAX (master setting, auxiliary setting).
3: MIN (master setting, auxiliary setting).
4:
Master s auxiliary setting × master setting maximum output frequency

5:
Master setting – auxiliary setting × master setting maximum output frequency

First, calculate the gain by using F19.02, then calculate auxiliary frequency according to the frequency
characteristic curve of Group F05.
• When F19.00 = 4,5, F19.02 is enabled.
F19.03

Only when F19.00 = 1 or 2 will F19.04 be enabled.
Units: Save selection at power outage
• 0: Not save auxiliary frequency at power outage.
• 1: The auxiliary frequency will be saved to F19.03 at power outage.
Tens: Frequency disposal when the inverter stops
• 0: Maintain the auxiliary frequency when the inverter stops.
• 1: The auxiliary frequency will be restored to F19.03 when the inverter stops.

F19.05 and F19.06 is to set the adjustment mode of setting frequency (the compounded frequency is
computed by master setting frequency plus auxiliary setting frequency).
0: No adjustment.
• Setting frequency = compounded frequency.
1: To adjust as per the max. output frequency of F00.06.
• Setting frequency = compounded fre F00.06 ×
(F19.06 - 100
％
).
2: To adjust as per the current frequency.
• Setting frequency = compounded frequency × F19.06.

0: Auto stop mode.
• The fan runs all the time when the inverter is in running status. After the inverter stops for the time
set by F19.08, the fan stops if the inverter is not overheated. The fan will continue running if the
overheat protection is activated.
1: Immediate stop mode. The fan runs all the time when the inverter is in running status and stops when
the inverter stops.
2: The fan runs continuously when power on. The fan runs continuously after the inverter is switched on.

This function is used in the application that several inverters drive one motor. The function can make the
inverters share the load equally.
When the load of one inverter is heavier, this inverter will reduce its output frequency to shed part of the
load according to the setting of F19.09.
