PowerFlex 755TL/TR Drive
Control
The PowerFlex 755TL/TR drives exclude any standard or optional door-
mounted operator devices. Precharge normally occurs when the input
disconnect, FD1, is closed. When precharge is completed the AC input MCB
circuit breaker, CB1, is closed automatically. If 0:63 [LS Start Mode] is set to
‘0’=’FLW MSideInv’ the line side converter IGBT modulation will start
automatically when the drive is started and is active in any motor control power
output mode (jog, run, stopping, and so on). When the drive is stopped, line
side converter IGBT modulation is stopped after the time delay set in 13:43
[LSC TurnOffDelay] expires (default = 5.0 seconds). When line side
converter IGBT modulation is stopped the line side converter transistors are
disabled, however, diode rectifiers in the line side converter IGBT power
devices are active. In this case, there will DC bus voltage available even when
line side converter IGBT modulation is stopped.
The following wiring diagrams show typical power and control power
connections to a frame 8 PowerFlex 755TL low harmonic drive with control
options; Torque Accuracy Module (control option catalog code -C0) and
RWR output filter (filter catalog code –M). The user-supplied 24V DC
auxiliary control power is shown connected, but the drive will function
without this power supply. The PowerFlex 755TR regenerative drive has the
same power and control connections.
