Features
.1
Programming provides the ability to select sensorless vector or V/Hz mode. The
sensorless vector mode uses motor nameplate data plus motor operating data
such as IR drop, nominal flux current and flux up time. The volts per hertz mode
shall be programmed as a straight line, pre-programmed fixed boost or full
custom patterns.
.2
Programmable current limit from 20% to 250% of constant torque rating. Current
limit is active for all drive states; accelerating, constant speed and decelerating.
The drive employs PI regulation with an adjustable gain for smooth transition in
and out of current limit.
.3
Multi-Accel/Decel settings provide separate adjustments to allow either setting to
be adjusted from 0.0 seconds to 3000.0 seconds. An adaptive current limit circuit
can be disabled in programming for fast acceleration of low inertia loads.
.4
The programmable speed regulation modes include the following:
.1
Open Loop
.2
Slip Compensation with 0.5% speed regulation
.3
Droop - Negative Slip Compensation with 0.5% speed regulation
.4
Closed loop encoder feedback with 0.1% speed regulation
.5
Process PI control
.5
Programming capability allows the user to produce speed profiles with linear
acceleration/deceleration or "S-Curve" profiles that provide changing accel/decel
rates. S-Curve profiles shall be selectable for fixed or adjustable values.
.6
The internal process PI regulator has both proportional and integral gain
adjustments as well as error inversion and output clamping functions. The
feedback can be configured for normal or square root functions. If the feedback
indicates that the process is moving away from the set point, the regulator will
adjust the drive output until the feedback equals the reference. Process control
can be enabled or disabled with a hardwire input. Transitioning in and out of
process control can be tuned for faster response by preloading the integrator.
Protection is provided for a loss of feedback or reference signal. A signal can
also be provided to indicate that excess error exists.
.7
The control logic is capable of "riding through" a power outage of at least 2
seconds in duration. The inverter section is shut off after a drop in bus voltage to

conserve power for the drive logic. The amount of drop required will be
adjustable to 50% of nominal.
.8
The drive can respond to a loss of AC input power by adjusting the output
frequency to create a regenerative situation in the motor. This regenerated
energy recaptures the mechanical energy and converts it to electrical energy to
power the drive logic during the power outage. This allows the drive to retain
control of the motor during the power outage. Performance is based on the
amount of system inertia and the length of the outage. The amount of voltage
drop required to trigger inertia ride through and the level at which regulation
occurs shall both be adjustable. Inertia Ride Through can be enabled or disable
via programming.
.9
DC Bus regulation is available to reduce the possibility of drive over-voltage trips
due to regenerative conditions. Bus voltage is monitored and an internal
regulator, triggered by a 15% rise in voltage, adjusts the drive’s output frequency
to maintain bus voltage at a nominal (100%) level. Bus regulation can be enabled
or disabled via programming.
.10
The VFD shall run under selectable PWM switching frequency and upon overtemperature shall fold-back the switching frequency to reduce the operating
temperature. The VFD shall return to the rated switching frequency after the
over-temperature condition has passed.
.11
The drive provides up to nine automatic fault reset and restarts following a fault
condition before locking out and requiring manual restart. The automatic mode is
not applicable to a ground fault, shorted output faults and other internal
microprocessor faults. The time between restarts is adjustable from 0.5 seconds
to 30.0 seconds.
.12
Enabled or disabled via programming, this feature allows the user to select the
output current level that indicates that the load has been disconnected (broken
belt / shaft / coupling) from the motor is indicated. Action is also selectable.
.13
Minimum of three (3) adjustable set points that lock out continuous operation at
frequencies which may produce mechanical resonance are provided. The set
points have an adjustable bandwidth.
.14
Minimum last four faults, as well as operating frequency, drive status and power
mode, shall be stored at the time of fault. Information is maintained in the event
of a power loss.
.15
The drive will provide Class 10 motor overload protection and motor stall
protection. Overload protection is speed sensitive and adjustable for motors with
speed ranges of 2:1, 4:1 and 10:1. A viewable parameter stores the overload
usage in percent. An alarm bit can be used to adjust a process to eliminate an
overload trip.
.16
The drive is capable of determining the speed and direction of a spinning motor
and adjusts its output to "pick-up" the motor at the rotating speed. The flying start
feature is operable with or without encoder feedback.

Summary of Ratings & Characteristics
.1
The transfer switch shall be 100% equipment rated for continuous duty as shown
on the drawings and shall conform to the applicable requirements of CSA C22.2
No. 178 for emergency system total load.
.2
The automatic transfer switches shall be fully rated to protect all types of loads,
inductive and resistive, from loss of continuity of power, without de-rating, either
open or enclosed.
.3
The transfer switch shall have withstand, closing and interrupting ratings (shortcircuit rating) sufficient for the voltage and the available short circuit current at the
point of application.
.4
The transfer switch shall be rated for application with upstream over-current
protective devices that do not incorporate instantaneous trip units having short
time delay settings of up to 30 cycles. Contacts shall not weld when used as
specified.
.5
The transfer switch shall provide complete protection with field adjustable
microprocessor based voltage sensing logic to monitor each phase (line to
neutral) of the normal and alternate power supply.
Construction
.1
Transfer switch shall consist of completely enclosed contact assemblies and a
separate control logic panel. The contact assemblies shall be operated by a nonfused motor operator or stored energy mechanism and be energized only
momentarily during transfer, providing inherently double throw switching action.
Control power for transfer operations shall be derived from the line side of the
source to which the load is being transferred to.
.2
Transfer switch shall be capable of being operated manually under full load
conditions. Manual operation shall be accomplished via a permanently affixed
manual operator or integrally mounted pushbutton operators located on the face
of the contact assemblies. Removable manual operating handles and handles
which move in the event that electrical operators should suddenly become
energized while performing a manual transfer operation are not acceptable. The
manual operator shall provide the same contact-to-contact transfer time as
provided under normal automatic operation to prevent possible flashovers from
switching the main contacts slowly. In addition, provisions shall be made to allow
disengagement of the electrical operator during manual operation.
.3
Transfer switch shall be positively interlocked both mechanically and electrically
to prevent simultaneous closing of both sources under either automatic or
manual operation. Main contacts shall be mechanically locked in position in both
normal and emergency positions. A neutral position shall not be possible under
normal electrical operation unless a delayed transition accessory is required for
switching highly inductive loads. Each transfer switch shall have a manual neutral
