The Motor and Application Control Block is based on microprocessor software. The
microprocessor controls the motor based on the information it receives through
measurements, parameter settings, control I/O and control keypad. The motor and
application control block controls the motor control ASIC which, in turn, calculates the IGBT
positions. Gate drivers amplify these signals for driving the IGBT inverter.
The control keypad constitutes a link between the user and the drive. The control keypad is
used for parameter setting, reading status data and giving control commands. It is
detachable and can be operated externally and connected via a cable to the drive. Instead of
the control keypad, a PC can also be used to control the drive if connected through a similar
cable (±12V).
You can have your drive equipped with a control I/O board which is either isolated (OPT-A8)
or not isolated (OPT-A9) from the frame. Optional I/O expander boards that increase the
number of inputs and outputs to be used are also available. For more information, contact
Eaton or your local distributor.
The basic control interface and the parameters (the Basic Application) are easy to use. If a
more versatile interface or parameters are required, a more suitable application can be
chosen from the application manual.
An internal brake chopper is available as standard for chassis CH3. For all other sizes the
brake chopper is available as an option and installed externally. The standard product does
not include a brake resistor. It should be ordered separately.
