
When the offset is higher than the setting of Pr.10.12 for a time exceeding the setting of
Pr.10.13, PID feedback signal fault occurs and operates by the treatment set in Pr.10.09.

Related parameters: Pr.10.00(PID Set Point Selection), Pr.10.01(Input Terminal for PID
Feedback), Pr.10.09(Treatment of the Erroneous PID Feedback Signals) and Pr.10.12(PID
Offset Level)
10.17
Minimum PID Output Frequency Selection
Factory Setting: 0
Settings 0 By PID control
1 By Minimum output frequency (Pr.01.05)

This is the source selection of minimum output frequency when control is by PID.

The output of the AC motor drive will refer to this parameter setting. When this parameter is
set to 0, the output frequency will output by the calculation of PID. When this parameter is set
to 1 and Pr.01.08 is not set to 0, the output frequency=Pr.01.08 setting. Otherwise, the output
frequency=Pr.01.05 setting.

Related parameters: Pr.01.05(Minimum Output Frequency (Fmin) (Motor 0)) and
Pr.01.08(Output Frequency Lower Limit)
10.14 Sleep/Wake Up Detection Time Unit: second
Settings 0.0 to 6550 sec Factory Setting: 0.0

If PID frequency is less than the sleep frequency when the drive starts running, the drive will
be in sleep mode immediately and won’t limit by this parameter.

Related parameters: Pr.10.15(Sleep Frequency) and Pr.10.16(Wakeup Frequency)
10.15 Sleep Frequency Unit: Hz
Settings 0.00 to 599.00 Hz Factory Setting: 0.00

This parameter set the frequency for the AC motor drive to be in sleep mode.

The AC motor drive will stop outputting after being sleep mode, but PID controller keep
operating.
10.16 Wakeup Frequency Unit: Hz
Settings 0.00 to 599.00 Hz Factory Setting: 0.00

This parameter is used to set the wakeup frequency to restart the AC motor drive after sleep
mode.

The wake up frequency must be higher than sleep frequency.

When the actual output frequency

Pr.10.15 and the time exceeds the setting of Pr.10.14,
the AC motor drive will be in sleep mode and the motor will decelerate to stop by
Pr.01.10/01.12 setting.

When the actual frequency command > Pr.10.16 and the time exceeds the setting of Pr.10.14,
the AC motor drive will restart.

When the AC motor drive is in sleep mode, frequency command is still calculated by PID.
When frequency reaches wake up frequency, AC motor drive will accelerate from Pr.01.05
minimum frequency following the V/f curve.
