Example 1) [AH-85] sleep start: 01 (output low)
• Sleep operation starts will start when the output
frequency stays below the level of [AH-86]
continuously for the set time of [AH-87].
Example 2) [AH-85] sleep start: 01 (output low)
• Sleep operation will start when the output
frequency stays below [AH-86] continuously for the
set time of [AH-87].
Example 3) [AH-85] sleep start: 02 ([SLEP] terminal)
• Sleep operation starts after the elapse of [AH-87]
from the ON edge of the [SLEP] terminal.
[AH-93] Sleep cancel: 01 (deviation amount)
• Cancel operation will start when PID deviation
stays over [AH-96] continuously for the set time of
[AH-95]. Deviation operates with either figure (±).
[AH-93] Sleep cancel: 02 (feedback low)
• Cancel operation will start when feedback stays
below [AH-94] continuously for the set time of
[AH-95].
[AH-93] Sleep cancel: 03 ([WAKE] terminal)
• Sleep operation will start after the elapse of [AH-95]
from the ON edge of the [WAKE] terminal.
