LEESON FHP Series NEMA 4x Variable Speed Drive - Manual (Page 38)

Line starting and line stopping
Warning
LEESON
strongly recommends the installation of
a master power switch in the voltage input line (see
Power and Fuse connections, page 1 1). The switch
contacts should be rated at a minimum of 200% of
motor nameplate current and 250 volts.
ƽ
Line starting/line stopping (applying and removing AC
voltage input) may be configured to operate two different
ways by use of JMP503.
When JMP503 is set to the UV TRIP position as shown in
Figure 15 (page 30), the drive will stop and latch off when
an under voltage condition, (bus voltage drops below
200VDC), occurs. This can occur due to line sag, line
transients, or line disconnect. The drive may then be
restarted by cycling the ENABLE off then on, or waiting until
the DC bus drops to zero, (approximately 1 minute), at
which point the drive will restart upon reapplication of line
power. Refer to Figure 4 (page 4) for Jumper Locations.
