Ramp to a stop by Bn-02, When RS-485 has communication error.
Coasting to a stop, When RS-485 has communication error.
Ramp to a stop by Bn-04, When RS-485 has communication error.
Operation to continue (will stop if the key stop is pressed)
(9) Operation Mode Select 6 (Sn-09)
1st, 2nd digit (Not used)
3rd digit (energy-saving function selection)
3rd digit = 0
：
Energy-saving function ineffective and operation is performed with
normal V/f control.
3rd digit = 1
：
Energy-saving function effective.
4th digit (Not used)
(10) Protective Characteristics Select 1 (Sn-10)
1st digit (selection of stall prevention during acceleration)
1st digit = 0
：
Stall prevention during acceleration is enabled.
1st digit = 1
：
Stall prevention during acceleration is not enabled.
The function of stall preventionduring acceleration automaticaIly extends accelration
according to load status (inverter output current), thus preventing the motor from
stalling during acceleration. The stall prevention level during acceleration in a
constant output area is reduced as follows:
When the 1st digit of Sn-10 is 1, the output frequency increases at the rate
determined by acceleration time:
2nd digit (selection of stall prevention during deceleration)
2nd digit = 0
：
Stall prevention during deceleration is enabled.
2nd digit = 1
：
Stall prevention during deceleration is not enabled.
The function of stall prevention during deceleration automatically extends
deceleration time according to the magnitude of the main circuit DC voltage, thus
preventing overvoltage during deceleration.
