Exceptional by Design™

Built-in Reliability and Performance

What makes the TMdrive-MVe2 Exceptional by Design™?

• Very High Reliability – 15 year MTBF

• Simple design

• Clean power to the utility system & motor

• Built-in Reactive Power Control

• Minimal spare parts

• Long-life film capacitors

• 24 hour x 365 day live support in North America

• Remote Connectivity troubleshooting built-in

The real power (kW) and the reactive power (kVAR) are related like the legs of a right triangle as in the figure at the above

right. Each of the sides is shown as an arrow, called vectors. Since they are at right angles, they cannot simply be added together.

The longer vector (kVA) represents the total current (amperes) and the load on the system. The ratio [kW / kVA] of real power

(kW) to apparent Power (kVA) is called the power factor (pf).  The angle shown as A is the power factor angle.  If all kVAR were

eliminated, the apparent power (kVA) and real power (kW) would be equal and the power factor would be unit or 1.00.

nv Series Controller

The nv Series Controller combines high-speed performance, integrated I/O,

and a unified hardware-software platform to deliver reliable, secure automation

for both process and factory environments.

Unified Control with High-Speed, High-Reliability Performance

The nv Series Controller streamlines automation by integrating multiple controller

types into a single, high-performance platform featuring a common I/O system.

With TC-net I/O and high-speed serial communication, it supports duplex loop

configurations at 100 Mbps, delivering exceptional reliability and fast response

times. Its unified hardware design and optimized software ensure robust operation,

compact installation, and secure control across process and factory automation

environments.

Specifications of TMdrive-30 and TMdrive-P30

Features

(1) High performance and high reliability

Use of a large capacity IGBT improves the reliability, reduces the switching loss, and improves the control

performance. The control circuit uses a newly developed power electronics equipment control processor

PP7 and an eight-layered surface mounting circuit board, ensuring high component integration and high

reliability.

(2) Highly precise speed control (TMdrive-30)

Use of totally digital and vector control ensures highly precise speed control and high speed response.

(ωc = 60 rad/s, ωc = 20 rad/s for speed sensor-less control)

(3) Transient response and stability

Use of totally digital and vector control makes it possible to ensure stable operation characteristics

including the transient status.

(4) Quadrantal operation (TMdrive-30)

Quadrantal operation, normal, reverse, power running, and regenerative operations are made smoothly.

(Note: This feature applies only when the reverse-parallel thyristor converter (TMdrive-T30) or IGBT

converter (TMdrive-P30) is used.)

(5) Supporting various speed sensors (TMdrive-30)

Drives a squirrel-cage induction motor. A pulse generator or high-resolution brushless resolver can be

used as a speed detector installed in the motor. Speed sensor-less vector control is also possible.

TMdrive-30 is a totally digital- and vector-controlled sine wave PWM inverter that performs highly precise and

efficient variable speed control of AC motors with a small to medium capacity. Also, TMdrive-P30 is an IGBT

converter that receives the AC power supply and converts it into the DC power for the IGBT inverter. This

equipment is power supply system-friendly because it controls the input current as sin wave. Before starting

operation of this equipment, thoroughly read this instruction manual to fully understand its contents.

This manual consists of the specifications of the equipment, names of blocks, concept of control, startup and

operation of the equipment, fault and recovery, maintenance points, and describes maintenance and operation

after the installation of the equipment.
