8Q9 ASD Quick Start Guide
System Setup Requirements
• When using the ASD as an integral part of a larger system, it is the responsibility of the ASD
installer/maintenance personnel to ensure that there is a fail-safe in place (i.e., an arrangement
designed to switch the system to a safe condition if there is a fault or failure).
• System safety features should be employed and designed into the integrated system in a manner
such that system operation, even in the event of system failure, will not cause harm or result in
system damage or injury to personnel (i.e., E-Off, Auto-Restart settings, System Interlocks, etc.).
• The programming setup and system configuration of the ASD may allow it to start the motor
unexpectedly. A familiarity with the Auto-Restart settings are a requirement to use this product.
• There may be thermal or physical properties, or ancillary devices integrated into the overall system
that may allow for the ASD to start the motor without warning. Signs must be posted to this effect
at the equipment installation location.
•DO NOT install power factor improvement capacitors or surge absorbers on the output of the ASD.
• Use of the built-in system protective features is highly recommended (i.e., E-Off, Overload
Protection, etc.).
• The operating controls and system status indicators should be clearly readable and positioned
where the operator can see them without obstruction.
• Additional warnings and notifications shall be posted at the equipment installation location as
deemed required by Qualified Personnel.
• Follow all warnings and precautions and do not exceed equipment ratings.
•The Dynamic Braking function is not used with the Q9 ASD.
•DO NOT attempt to configure or connect the DBR function to the Q9 ASD.
• Attempts to configure or adapt the ASD to use the Dynamic Braking function may result in system
damage or injury to personnel.
• If a secondary magnetic contactor (MC) or an ASD output disconnect is used between the ASD and
the load, it should be interlocked to halt the ASD before the secondary contact opens. If the output
contactor is used for bypass operation, it must be interlocked such that commercial power is never
applied to the ASD output terminals (U, V, or W).
• When using an ASD output disconnect the ASD and the motor must be stopped before the
disconnect is either opened or closed. Closing the output disconnect while the 3-phase output of the
ASD is active may result in equipment damage or injury to personnel.

10 Q9 ASD Quick Start Guide
Installation and Connections
The ASD 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
R/L1, S/L2, and T/L3 terminals). The control terminals of the ASD may be used by connecting the
terminals of the Terminal Board (P/N 072314P903) to the proper sensors or signal input sources (See
the section titled I/O and Control on pg. 17
and Figure 9 on pg. 20).
System performance may be further enhanced by assigning a function to the output terminals of the
Terminal Board and connecting the terminals to the proper indicators or actuators (LEDs, relays,
contactors, etc.).
Note: The optional Q9 ASD interface boards may be used to expand the I/O functionality of
the ASD.
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, DONOT 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 (U/T1, V/T2, and W/T3).
DO NOT apply commercial power to the ASD output terminals U/T1,V/T2, and W/T3.
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 Q9 ASD is on or while the
motor is still turning may cause ASD damage.
The Q9 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 over-voltage and under-
voltage 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 higher than the rated output of the ASD.
The Q9 ASD is designed to operate NEMA B motors. Consult with your Toshiba Sales Representative
before using the ASD for special applications such as with an explosion-proof motor or applications
with a piston load.
Disconnect the ASD from the motor before megging or applying a bypass voltage to the motor.
Interface problems may occur when an ASD is used in conjunction with some types of process
controllers. Signal isolation may be required to prevent controller and/or ASD malfunction (Contact
your Toshiba Sales Representative or the process controller manufacturer for additional information
about compatibility and signal isolation).
Use caution when setting the output frequency. Over-speeding a motor decreases the ability to deliver
torque and may result in damage to the motor and/or the driven equipment.
