Sleep Wake Up function
All model and serial numbers
For PID setup see FAQ FA230136.
PID SLEEP WAKEUP can be enabled by setting F256 [Time limit low spd]
Setting this function to 0 disables this function.
The range of this function is between 0 and 600 seconds. 0 disables this function.
If parameter F256 is enabled and if the drive operates continuously at [Low limit frequency] (LL) for a time period equal to the setting of F256, the drive will ramp the motor to a stop. While the motor is stopped, “LStP” will flash on the drive
embedded display terminal.
When the speed reference to the drive exceeds the low speed level LL+F391, the drive will accelerate the motor to the new speed
