When the output frequency is less than Motor Minimum Output Frequency (P2.08, P2.16), the GS4
drive will operate by this parameter.
When P2.18 is set to 0, the GS4 drive will be in waiting mode with no voltage output from terminals
U/V/W.
When P2.18 is set to 1, the GS4 drive will execute DC brake by Motor Minimum Output Voltage
(P2.09, P2.17) in V/Hz and SVC modes.
When P2.18 is set to 2, the GS4 drive will run by Motor Minimum Output Frequency (P2.08, P2.16)
and Motor Minimum Output Voltage (P2.09, P2.17) in V/Hz and Sensorless Vector modes.
When P2.18 is set to 2, and if the setting of P6.26 (Output Frequency Lower Limit) is higher than
Motor Minimum Output Frequency, then the GS4 drive will run in accordance with the setting of
P6.26 in V/Hz and SVC mode.
