Rapid-Air SERVO FEED / RAPID MASTER - Manual (Page 4)


If you purchased the Servo/Rapid
Master combination already mounted
on a base then the servo and press
were aligned at the factory. A good
practice is to check all hold down
bolts to be sure that they did not come
loose during shipment.
If you purchased the servo and
press and are going to mount it on
a base at your facility, then a base
should be selected that will hold the
weight of the servo and the press
and also the cycling shocks incurred
during production.
When mounting the two devices.
The pass line height of the press
and the servo roller center line
should be equal. Even more critical
is the parallelism between the
two devices. The press should be
installation, set-up, and cabling
mounted first then the servo center
line should be aligned to the press
center line with the servo rollers
parallel to the press blade.
The servo should be mounted as
close to the press as possible and de-
pending on thickness of the material
a bridge should be installed between
the servo and press to minimize mate-
rial droop or buckling during feed.
120.VAC.INPUT
The alternate input voltage to the
control is 120 Vac, 1 Ph, 60 Hz. The
max amperage needed is 7.5 amps
and the control has a circuit breaker
with a trip amperage of 10 amps.
230.VAC.INPUT
The required input voltage to the
control is 230 Vac, 3 Ph, 60 Hz. The
amperage needed is 10-20 amps
depending on the motor size. If
unsure of the amperage needed, the
name plate on the side of the Pacific
Scientific drive will give the number
of the control or check the disconnect
fuses for the correct fuse size.
460.VAC.INPUT
If your plant has only 460 Vac power
then a step down transformer is
needed in order to run the servo feed.
If you purchased the transformer from
Rapid-Air, then all that is needed is to
connect and wire the 460 volt line to
the transformer. If you did not pur-
chase a transformer from Rapid-Air
then a transformer, 3 KVA for the 100S
and 200S servos and 6KVA for the
300S servos, 460/230 Vac 3 Ph, 60Hz
step down transformer is needed
before proceeding with the electrical
portion of the installation.
The electrical control enclosure is
shipped completely ready to be con-
nected to the mechanical feed. Con-
nected to the bottom of the enclosure
are (2) cables with keyed screw type
connectors for connection to the mo-
tor. If the series 200 was purchased,
(1 or 2) push-on connectors for con-
nection to the air valves for solenoid
actuation of the pilot release and or
anti-backup valve are included. The
third connector is used to interface
the press to the controls.
Position the electrical enclosure at a
convenient location near the mechan-
ical feed and attach the cables. The
motor cables are easily identifiable by
the amount of pins in the plugs. The
solenoid cables if any can now be at-
tached and checked for proper loca-
tion when the feed is up and running.
An air line must be connected from
the shop air to the air inlet of the ser-
vo feed. The air should be at least 80
PSI continuous and should be dry filtered
and lightly lubricated for the best opera-
tion of the servo feed. The air inlet on the
servo feed is a 3/8-18 NPT pipe tap. The
minimum air line size requirement
is 1/2” lD hose. - (2 CFM)
