12 Q7 ASD Installation and Operation Manual
Motor Characteristics
Listed below are some variable speed AC motor control concepts with which the user of the
Q7 Adjustable Speed Drive should become familiar.
Pulse Width Modulation Operation
The Q7 ASD uses a sinusoidal Pulse Width Modulation (PWM) control system. The output current
waveform generated by the ASD approaches that of a perfect sine wave; however, the output waveform
is slightly distorted. For this reason, the motor may produce more heat, noise, and vibration when
operated by an ASD, rather than directly from commercial power.
Overload Protection Adjustment
The Q7 ASD software monitors the output current of the system and determines when an overload
condition occurs. The overload current level is a percentage of the rating of the motor. This function
protects the motor from overload.
The default setting for the overload detection circuit is set to the maximum rated current of the ASD at
the factory. This setting will have to be adjusted to match the rating of the motor with which the ASD is
to be used. To change the overload reference level, see (Electronic) Thermal Protection #1 on pg. 62.
Power Factor Correction
DO NOT connect a power factor correction capacitor or surge absorber to the output of the ASD.
If the ASD is used with a motor that is equipped with a capacitor for power factor correction, remove
the capacitor from the motor.
Connecting either of these devices to theoutput of the ASD may cause the ASD to malfunction and trip,
or the output device may cause an over-current condition resulting in damage to the device or the ASD.
Light Load Conditions
When a motor is operated under a continuous light load (i.e., at a load of less than 50% of its rated
capacity) or it drives a load which produces a very small amount of inertia, it may become unstable and
produce abnormal vibration or trips because of an over-current condition. In such a case, the carrier
frequency may be lowered to compensate for this undesirable condition (see Program
⇒ Special
Control Parameters
⇒ PWM Carrier Frequency).
Note: For proper operation, the carrier frequency must be 2.2 kHz or above except when
operating in the Constant Torque or Variable Torque modes.
Load-produced Negative Torque
When the ASD is used with a load that produces negative torque (an overhauling load), the over-voltage
or over-current protective functions of the ASD may cause nuisance tripping.
To minimize the undesirable effects of negative torque the dynamic braking system may be used. The
dynamic braking system converts the regenerated energy into heat that is dissipated using a braking

Q7 ASD Installation and Operation Manual 13
resistor. The braking resistor must be suitably matched to the load. Dynamic braking is also effective in
reducing the DC bus voltage during a momentary over-voltage condition.
If under extreme conditions the dynamic braking system or a component of this system were to fail, the
dynamic braking resistor may experience an extended over-current condition. The DBR circuit was
designed to dissipate excessive amounts of heat and if the extended over-current condition were allowed
to exceed the circuit parameters, this condition could result in a fire hazard.
To combat this condition, the 3-phase input may be connected using contactors that are configured to
open in the event of an extended DBR over-current condition or an internal circuit failure. Using a
thermal sensor and/oroverload protection as the 3-phase input contactor drive signal, the contactors will
open and remove the 3-phase input power in the event of an extended DBR over-current or system over-
voltage condition.
Motor Braking
The motor may continue to rotate and coast to a stop after being shut off due to the inertia of the load. If
an immediate stop is required, a braking system should be used. The two most common types of motor
braking systems used with the Q7 ASD are DC Injection Braking and Dynamic Braking.
For further information on braking systems, see DC Injection Braking Current on pg. 57 and
Dynamic Braking Enable on pg. 60.
ASD Characteristics
Over-current Protection
Each Q7 ASD model was designed for a specified operating power range. The ASD will incur a trip if
the design specifications are exceeded.
However, the ASD may be operated at 100% of the specified output-current range continuously or at
110% for a limited time as indicated in the section titled Current/Voltage Specifications on pg. 162.
Also, the Overcurrent Stall Level setting may be adjusted to help with nuisance over-current trips.
When using the ASD for an application that controls a motor which is rated significantly less than the
maximum current rating of the ASD, the over-current limit (Thermal Overload Protection) setting will
have to be changed to match the application. For further information on this parameter, see (Electronic)
Thermal Protection #1 on pg. 62.
ASD Capacity
The Q7 ASD must not be used with a motor that has a significantly larger capacity, even if the motor is
operated under a small load. An ASD being used in this way will be susceptible to a high-output peak
current which may result in nuisance tripping.
Do not apply a level of input voltage to an ASD that is beyond that which the ASD is rated. The input
voltage may be stepped down if required with the use of a step-down transformer or some other type of
voltage-reduction system.
CAUTION

14 Q7 ASD Installation and Operation Manual
Installation and Connections
The Q7 Adjustable Speed Drive may be set up initially by performing a few simple configuration
settings. To operate properly, the ASD must be securely mounted and connected to a power source (3-
phase AC input at the L1/R, L2/S, and L3/T terminals). The control terminals of the ASD may be used
by connecting the terminals of the Control Terminal Strip to the proper sensors or signal input sources
(see the section titled I/O and Control on pg. 19).
The output terminals of the ASD (T1/U, T2/V, and T3/W) must be connected to the motor that is to be
controlled (see Figure 18 on pg. 26).
As a minimum, the installation of the ASD shall conform to Article 110 of the 2005 NEC, the
Occupational Safety and Health Administration requirements, and to any other local and regional
industry codes and standards.
Installation Notes
When a brake-equipped motor is connected to the ASD, it is possible that the brake may not release at
startup because of insufficient voltage. To avoid this, Do Not connect the brake or the brake contactor to
the output of the ASD.
If an output contactor is used for bypass operation, it must be interlocked such that commercial power is
never applied to the output terminals of the ASD (T1/U, T2/V, or T3/W).
If a secondary magnetic contactor (MC) is used between the output of the ASD and the motor, it should
be interlocked such that the ST – CC connection is disconnected before the output contactor is opened.
Do Not open and then close a secondary magnetic contactor between the ASD and the motor unless the
ASD is off and the motor is not rotating.
Note: Re-application of power via a secondary contact while the ASD is on or while the
motor is still turning may cause ASD damage.
On some devices the ST-to-CC connection is further enhanced by the operation of the MS1 AUX relay
circuit. The MS1 AUX relay circuit is normally open and closes the ST-to-CC connection (via ST1)
only after normal system power is available. The MS1 AUX relay circuit prohibits the ST-to-CC
connection in the event that the MS1 contactor fails to close during start up or if MS1 opens while the
ASD is running. For the 230 volt ASD this feature is available on the 40 HP and above systems, on the
460 volt ASD this feature is available on the 75 HP and above systems, and on the 600 volt ASD it is
available on the 60 HP and above systems.
Figure 2. Alternative ST activation using the MS1 AUX circuit configuration.
The ASD input voltage should remain within 10% of the specified input voltage range. Input voltages
approaching the upper or lower limit settings may require that the overvoltage and undervoltage stall
protection level parameters be adjusted. Voltages outside of the permissible tolerance should be
avoided.
The frequency of the input power should be ±2 Hz of the specified input frequency.
Do not use an ASD with a motor that has a power rating that is higher than the rated output of the ASD.
