ADJUSTABLE SPEED DRIVES
Q9 Series
Reliable & Configurable
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.
Configurable
Integrated Enclosure
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
DesignedforHVACSystems
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.
PIDControl
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®
