2.3 Specifications of TMdrive-30 and TMdrive-P30
This section describes the features of TMdrive-30 and specifications of TMdrive-P30.
2.3.1 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.
(
ω
c = 60 rad/s,
ω
c = 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.
(6)
High power factor (TMdrive-P30), high efficiency
A high efficiency drive system can be constructed due to high efficiency achieved by sine wave PWM
control and small device loss. Because TMdrive-P30 can control the power waveform as sine wave, it
reduces power supply higher harmonic waves and can control the power supply factor as high as 1.
(7)
Energy saving
With combined with a common converter (TMdrive-P30, TMdrive-T30 (reverse-parallel type)) having
power regeneration function, the energy is saved in applications where continuous regenerative operation
is made, or the acceleration and deceleration are made repeatedly.
The regenerative energy is stored as DC voltage and used to drive other inverters. Additionally, the power
is regenerated to the AC power supply by the common converter with the power regeneration function.
(8)
Maintenance tool (optional test and adjustment support tool)
Not only as a maintenance, monitoring, and fault analysis tool, this tool can also be used as an adjustment
tool. To change the parameters and collect traceback data, this tool is required.
(9)
Main unit (PC) transmission
Transmission via Toshiba integrated controller (V series) and TOSLINE-S20 can be performed. This
equipment also supports open transmission such as ISBus, Profibus, and DeviceNet (optional).
