Description of Parameters
Figure 8-52: Underload Time Counter Function
716 Underload time 234567 (P1.7.20)
This time can be set between 2.0 and 600.0s.
This is the maximum time allowed for an underload state to exist. An internal up/
down counter counts the accumulated underload time. If the underload counter value
goes above this limit the protection will cause a trip according to ID713. If the drive is
stopped the underload counter is reset to zero. See Figure 8-52 and Page A-5.
717 Automatic restart: Wait time 234567 (P1.8.1)
Defines the time before the frequency converter tries to automatically restart the
motor after the fault has disappeared.
