F3 Group Start And Stop Control Group; F4 V/F Control Group - Powtran PI500-S Series Manual

Chapter 5 Function parameter

5-1-5.F3 Group Start and stop control group

Code Parameter name
F3.00 Start-up mode
F3.03 Start frequency
F3.04 Hold time for start frequency 0.0s~100.0s
F3.05 DC Pre-excitation current
F3.06 DC Pre-excitation time
DC brake, generally used to stop and start the motor running. Pre-excitation is used to enable
the establishment of magnetic field induction motor and then start to improve the response speed.
DC brake is valid only in start-up mode for the direct start. At this point the drive to start first
by setting the DC braking current DC braking, DC braking time after the start and then start
running. If the set DC braking time is 0, no start directly after DC braking. DC braking current
increases, the greater the braking force.
If the start-up mode for the asynchronous machine to start pre-excitation, the drive pre-press
set excitation current pre-established field, after the set pre-magnetizing time before starting
operation. If the set pre-magnetizing time is 0, no pre-excitation processes started directly. DC
brake current / pre-excitation current, is the percentage of relative inverter rated current.
F3.07 Stop mode
F3.08 DC start frequency
F3.09 DC waiting time
F3.10 Stop braking current
F3.11 Stop braking current
