Installation And Connections; Installation Notes - Toshiba Q9 Plus ASD Quick Start Manual

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
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 Plus 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, 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 (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 Plus ASD is on or
while the motor is still turning may cause ASD damage.
The Q9 Plus 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 Plus ASD is designed to operate NEMA B motors. Consult with the TIC Customer Support
Center 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 the
TIC Customer Support Center 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.
