Notes for PID Sleep function
· The Stopping Method for PID Sleep function is determined by b1-02
· Set the PID Sleep function in b5-14 and b5-15.
b5- 14 PID Sleep Start Level
Sets the frequency level used to trigger PID Sleep.
PID Sleep will be triggered when the PID output or frequency command falls below the level
set to b5-14 for the time longer than the time set to b5-15. The drive will resume operation
when the PID output or frequency command exceeds the level set to b5-14 for longer than the
time set in b5-15.
<1> The upper limit is determined by the values set to d1-02 (Maximum Output Frequency), d1-13 (Motor 2
Maximum Output Frequency) and L2-00 (Frequency Command Upper Limit).
b5- 15 PID Sleep Delay Time
Sets the delay time used to activate/deactivate the PID Sleep function.
b5- 16 PID Acc./Dec. Time
The PID Acc. /Dec. time is used for the PID target.
When the PID target changes quickly, the normal C1-□□ Acc. time decreases the response
