WARNING
Flux braking can cause heat in the motor. To avoid damage to the motor, use a PTC
to protect the motor. If the flux brake is used too frequently, the drive will trip fault
"F_PF".

599 • 0 = Normal Run Screen, this display depends
on mode of operation. Refer to section 4.2.
• Other selections choose a diagnostic
parameter to display (P501...P599).
• Parameters P560 - P564 are selectable
if the sequencer is enabled (P700 is not
0). P560-P564 are not visible until P700
is enabled.

• P181 and P182 define the start of the
skip ranges
• P184 > 0 defines the bandwidth of both
ranges.

mode. Use to reduce deceleration time on high
inertia loads.
