YASKAWA P1000 Technical Manual

For Reverse Acting PID, the PID Feedback must rise above the b5-94 level for the time set in b5-96 in order for the drive to
wake-up.
Wake-up using Setpoint Delta Level (b5-95 = 1)
For Normal Acting PID, the wake-up level is determined by the PID Setpoint minus the b5-94 level. The PID Feedback must
drop below the wake-up level for the time set in b5-96 in order for the drive to wake-up
For Reverse Acting PID, the wake-up level is determined by the PID Setpoint plus the b5-94 level. The PID Feedback must
rise above the wake-up level for the time set in b5-96 in order for the drive to wake-up.
Refer to Figure 5.19 and Figure 5.20 for detailed diagrams of EZ Sleep/Wake-up functions.
