Type Hex Addr Dec Addr
P7.26 PID Reverse Enable
R/W 071A 41819
Range/Units (Format: 16-bit binary) 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�
Type Hex Addr Dec Addr
P7.27 Source of Sleep
R/W 071B 41820
Range/Units (Format: 16-bit binary) Default
0: Frequency/PID Setpoint
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.
Type Hex Addr Dec Addr
P7.28 Integral Limit During Sleep
R/W 071C 41821
Range/Units (Format: 16-bit unsigned) 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.
The Wake-up Timer is not cumulative: the reference needs to stay above Wake-up Reference for the entire
length of Wake-up Delay, otherwise the Delay timer will reset.
