11 - 07 Enter Sleep Process Time
Factory Setting: 0.0
Settings 0.0~3600.0sec Unit: 0.1 Sec
This parameter is to set output frequency of AC drive being smaller than the time interval
between sleep frequency and enter sleep process.
When AC drive starts running, frequency command calculated by PID is smaller than sleep
frequency. AC drive will enter sleep status and won’t be limited by this parameter.
When AC motor drive is in sleep process, SLEEP will be displayed on the digital keypad till
frequency command attains to wake up frequecy.
11 - 08 Sleep Frequency of Sleep Process
Factory Setting: 0.00
Settings 0.00~11-09 (wake up frequency) Unit: 0.01
This parameter determines frequency after AC drive enters sleep process.
After AC drive enters sleep status, it will stop to output signal but PID controller will keep
working.
11 - 09 Wake Up Frequency of Sleep Process
Factory Setting: 0.00
Settings 0.00 to 120.00Hz Unit: 0.01
This parameter determines wake up frequency after AC drive enters sleep process.
PID control function will keep calculating frequency command (F) when AC drive is in sleep
process. When frequency command attains to wake up frequency, AC drive will accelerate
from 01-05 minimum frequency setting according to V/f curve.
The setting of wake up frequency needs to be greater than sleep frequency.
