1. OVERVIEW
The CombiDrive
®
is an integrated motor/inverter for variable speed applications.
The inverter is microprocessor-controlled and uses state of the art IGBT technology for reliability and flexibility.
A special pulse-width modulation method with ultrasonic pulse frequency permits extremely quiet motor
operation. Inverter and motor protection is provided by comprehensive protective functions.
Features:
•
Easy to install and commission.
•
Closed loop control using a Proportional, Integral (PI) control loop function.
•
High starting torque with programmable starting boost.
•
Remote control capability via RS485 serial link using the USS protocol.
•
Ability to control up to 31 CombiDrive
®
via the USS protocol.
•
Optional remote control capability via RS485 serial link using PROFIBUS-DP.
•
Factory default parameter settings pre-programmed for European and North American requirements.
•
Output frequency (and hence motor speed) can be controlled by one of four methods:
(1)
Built-in potentiometer.
(2)
High resolution analogue setpoint (voltage or current input).
(3)
Fixed frequencies via binary inputs.
(4)
Serial interface.
•
Built-in dc injection braking.
•
Acceleration/deceleration times with programmable smoothing.
•
Single signal relay output incorporated.
•
External connection for optional Clear Text Display (OPm2) or for use as external RS485 interface.
•
Fast Current Limit (FCL) for reliable trip-free operation.
•
Optional factory-fitted resistive braking unit (also available as a separate post-sale option).
•
Optional motor brake and interface.
•
Integral class A or class B filter options.
