Chapter 1 Drive Configuration
Sleep/Wake Mode The purpose of the sleep/wake function is to Start (wake) the drive when an
SleepWake RefSel signal is greater than or equal to the value in P354 [Wake
Level], and Stop (sleep) the drive when an analog signal is less than or equal to the
value in P352 [Sleep Level]. Setting P350 [Sleep Wake Mode] to 1 “Direct”
enables the sleep/wake function to work as described.
An Invert mode also exists that changes the logic so that an analog value less than
or equal to P354 [Wake Level] starts the drive and an SleepWake RefSel signal
greater than or equal to P352 [Sleep Level] stops the drive.
