Type Hex Addr Dec Addr
P7.26 PID Reverse Enable
R/W 071A 41819
Range/Units Default
0: PID can't change command direction
1: PID can change command direction
0
This parameter when engaged changes the ability of PID to change the direction of the drive.
•
When set to 0 it prevents PID from changing the direction of the output.
•
When set to a 1 it enables the changing of direction by the level of PID.

P7.27 Source of Sleep
R/W 071B 41820
Range/Units Default
0: Frequency
1: Feedback
0
This parameter allows a choice of setting the Sleep Mode function to be actuated by the Output
Command or the Feedback Signal.

P7.28 Integral Limit During Sleep
R/W 071C 41821
Range/Units Default
0.0~200.0
50.0
This upper integral limit of the drive is to avoid running at high speed right after the drive has been
awakened.

Parameters P7.29, P7.30, P7.31, P7.32:
The Sleep Reference point (P7.29) provides the setpoint at which, should the drive reach or go
below, causes the drive to go to sleep. When asleep the drive does nothing (its output being off)
besides monitoring its operating point.
In order to Wake-up and again operate, it should reach the Wake-up Reference point (P7.30). If the
Command Frequency falls below the Sleep Reference point (P7.29) for the Sleep Time specified in
P7.31, then the drive will shut off the output and wait until the Command Frequency rises above
what is set in Wake-Up Reference point (P7.30).
The Wake-up Delay Time (P7.32) delays the drive from Waking-Up once the Wake-Up Level has
been exceeded by the amount of time set in this parameter.
