Install and Wire the Drive 2-13
2.5.3 Wire AC-Power to the Drive
ATTENTION: The user is responsible for conforming to all applicable standards.
Wiring, grounding, disconnects and overcurrent protection are of particular
importance. Size and install all wiring in conformance with all applicable standards.
Failure to observe this precaution could result in severe bodily injury or loss of life.
ATTENTION: The drive requires a three-phase power source of ether 200 - 500 or
300 - 575/690 V, 50/60 Hz (see A-2). If the correct voltage is not available, a
transformer must be installed between power source and drive. Do not connect the
drive to a power source with available short circuit capacity in excess of the max.
symmetrical fault current listed in Appendix A, page A-1. Failure to observe this
precaution could result in bodily injury or equipment damage.
1. Size the AC line supply conductors for the specific drive rating (see figures 2.1 to 2.6) and
according to all applicable standards.
2. Connect the AC line supply via disconnect (if used) and line reactor or matched transformer
to the terminal strips or bus bars at the top of the converter or to the disconnect.
3. Tighten incoming AC line connections per tables in figures 2.1 to 2.6.
Important: The tightening torque in the table applies to the wiring device (stud or terminal
board) provided. When an input or an output device (breaker or lug kit) is added,
refer to the kit instructions for tightening specifications.
2.5.4 Wire the DC-Motor to the Drive
1. Size the motor armature circuit conductors for the specific drive rating (see figures 2.1 to
2.6) and according to applicable standards. Use only copper wire rated 60/70 ° C or higher.
2. Locate the DC-motor armature and field supply leads on the drive.
4. Connect the DC-motor armature leads and the shunt field supply leads to the drive.
5. Tighten armature connections per tables in figures 2.1 to 2.6.
2.5.4.1 Motor Overload Protection
A software (internal) static overload is provided. In addition to the software (internal) overload
function, a DC-motor thermostat can be used for motor thermal overload protection. The
thermostat leads are brought out through the motor terminal box as leads P1 and P2.
These two leads must be wired to the regulator board control terminals 13 and 14.
The thermostat leads can be run with the motor armature and field power wiring.
NOTE: The Drive will not start if the circuit between terminals 13 and 14 is not made.
See Figure 2.8b.
2.5.5 Wiring Stopping Devices to the Drive
2.5.5.1 Description of Stop Modes and Drive States
The WebPak 3000 drive can be stopped by the assertion of a stop input (which can be
configured as a ramp stop, a current limit stop, or a coast/DB stop), opening a permissive input
(coast/DB interlock or customer interlock), deassertion of the JOG FWD or JOG REV input, or
in the event of a fault. Depending on the type of stop, one of two different stop sequences are
executed to provide an orderly method of deactivating the armature.
To the internal sequencing algorithm, the drive is always in one of three states: armature not
active (main contactor open), run mode, or jog mode. The armature is not active while in the
NOT READY and READY states. The drive is considered to be in RUN mode if it was started
by the SECTION RUN input or the TENSION ON input.
