ADJUSTABLE SPEED DRIVES

Q9 Series

Reliable & Congurable

Reliable

Toshiba has manufactured pulse-width
modulated drives since 1981 and is one
of the few companies that manufactures
both motors and drives in the same
facility. Because of this, Toshiba has the
knowledge to develop and manufacture
the most powerful, efficient, and motor­friendly adjustable speed drives available.

Toshiba produces one of the most reliable
and rugged adjustable speed drives in the
industry. Users can rely on Toshiba drives
working for years beyond their warranty.

The Q9 is no exception — it is built to last.
Toshiba uses oversized transistors and
heavy-duty DC bus capacitors to extend
the drive’s life. The Q9 is listed at 100,000
AIC interrupting capacity. The drive is also
designed to operate in environments from

-10˚ to 40˚C at elevations up to 3,300 feet.

Integrated Enclosure

Congurable

The Q9 is not only a monster in durability and dependability, but also simple to use. The electronic
operator interface (EOI), with its LCD display and simple keypad layout, allows for quick and easy
menu and parameter navigation. Toshiba even provides optional Windows®-based software to
help with Q9 programming and monitoring.

With eight digital inputs, three digital outputs, three analog inputs, two analog outputs, EOI, and
various communication protocol options, the Q9 allows for flexibility in controlling and monitoring
the drive.

My Function is a Q9 feature that allows the user to access built-in PLC-type logic. My Function
provides basic logic programming without the need for an external PLC.

HVAC-Minded

Designed for HVAC Systems

The Q9 ASD is designed for HVAC systems offering many popular features needed in the industry.
It comes equipped with a fire-speed circuit that forces the drive to run at a preset speed during
a smoke purge. The Q9 also provides a damper-permissive function that can be used to protect
from over-pressuring ductwork.

A user can set a low-output disable time to force the drive to zero-speed if the drive runs at the
lower limit frequency for a specified time. This option helps reduce energy costs.

PID Control

A built-in proportional/integral/derivative (PID) controller, used to regulate a process without
the need for external control devices, comes standard with the Q9. In addition, the wire-break
function trips the drive if the feedback signal drops below specified levels. This prevents the drive
from accelerating to maximum speed and helps protect the system.

Communications

The Q9 supports many common
protocols used in HVAC applications
including:

• BACnet (MS/TP)

• LonWorks

• Metasys N2

• Modbus RTU

• APOGEE FLN
