  • Page 12 5.2 Modified PID “Sleep” Function In standard software, parameter B5-16 controls both the sleep delay, and the wake-up delay. In this software, parameter B5-16 controls the sleep delay, and P2-06 controls the wake-up delay. maximum settable range of B5-16 is increased from 25.5 seconds to 600.0 seconds. An additional timer has been added (P2-07) to the sleep function to insure that when the drive does go into the sleep mode, it remains in sleep mode even if the PID is calling for the drive to run.
