03- 06 Up/Down frequency step
Range
【0.00~5.00】Hz
Example: S1: 03- 00=【8】Up frequency command, S2：03- 01=【9】Down frequency command,
03- 06=【△】Hz
Mode1: If UP or DOWN input terminals are turned on for less than 2 seconds, for every On operation
frequency changes by △ Hz.

03- 07 Up/Down keep Frequency status after a stop command
Range
【0】: After a stop command in Up/Down mode, the preset frequency is held
as the inverter stops, and the UP/Down function is disabled.
【1】: After a stop command in Up/Down mode, the preset frequency is reset
to 0 Hz as the inverter stops.
【2】: After a stop command in Up/Down mode, the preset frequency is held
as the inverter stops, and the UP/Down function remains enabled.
03 - 07=0, 2 when run signal is removed (Stop Command), the output frequency is stored in
parameter 05-01( Key pad Frequency).
03 - 07=0, in stop mode since frequency can not be increased or decreased from Up/Down
terminals then keypad can be used to change the frequency by modifying parameter 05-01.
03 - 07=1, In Up/down frequency mode inverter will ramp up from 0Hz on Run command
and Ramp down to 0 Hz on stop command.
