T077 [Sleep-Wake Sel] Related Parameter(s): T078, T079, T080, T081
The drive “sleeps” if the appropriate analog input drops below the set [Sleep Level] for the time set in
[Sleep Time] and the drive is running. When entering sleep mode the drive will ramp to zero and the
run indicator ( ) on the keypad display will flash indicating the drive is in “sleep” mode.
When the appropriate analog input rises above the set [Sleep Level] the drive will “wake” and ramp to
the commanded frequency.
Inversion can be accomplished by setting T078 [Sleep Level] to a higher setting than T080 [Wake
Level].
Options 0 “Disabled” (Default)
1 “Analog In 1” Sleep enabled from Analog Input 1.
2 “Analog In 2” Sleep enabled from Analog Input 2.
3 “Command Freq” Sleep enabled based on drive commanded frequency.
