Application Notes

Appendix B

Sleep Wake Mode

This function stops (sleep) and starts (wake) the drive based on separately
configurable analog input levels rather than discrete start and stop signals. by
default, this function is disabled. The following Sleep/Wake modes are available:

1 “Direct” - In this mode, the drive will start (wake) when the analog input

signal is greater than or equal to the value set in [Wake Level] and the drive
will stop (sleep) when the analog input signal is less than or equal to the
value in [Sleep Level].

2 “Invert” - In this mode, the analog input signal used by the [Wake Level]

and [Sleep Level] parameters is inverted. In this mode, the drive will start
(wake) when the analog input signal is less than or equal to the value set in
[Wake Level] and the drive will stop (sleep) when the analog input signal is
greater than or equal to the value in [Sleep Level].

Definitions:

Wake - A start command generated when the analog input value remains

above [Wake Level] for a time greater than [Wake Time].

Sleep - A Stop command generated when the analog input value remains

below [Sleep Level] for a time greater than [Sleep Time].

Speed Reference – The active speed command to the drive as selected by

drive logic and [Speed Ref

x Sel].

Start Command - A command generated by pressing the Start button on

the HIM, closing a digital input programmed for Start, Run, Run Forward
or Run Reverse.
