1. OVERVIEW

The MICROMASTERS are a range of frequency inverters for controlling the speed of three phase AC motors. Various models are available, ranging from the compact 120 W single phase input MICROMASTER up to the 7.5 kW three phase input MICROMASTER.

The inverters are microprocessor-controlled and use state of the art IGBT technology for reliability and flexibility. A special pulse-width modulation method with selectable ultrasonic pulse frequency permits extremely quiet motor operation. Inverter and motor protection is provided by comprehensive protective functions.

Features:

∙Easy to install, program and commission.

∙Closed loop control using a Proportional, Integral (PI) control loop function.

∙High starting torque with automatic starting boost.

∙Remote control capability via RS485 serial link using the USS protocol with the ability to control up to 31 inverters.

∙A comprehensive range of parameters is provided to enable the inverters to be configured for use in almost any application.

∙Membrane-type front panel controls for simple operation.

∙Built-in non-volatile memory for storing parameter settings.

∙Factory default parameter settings pre-programmed for European and North American requirements.

∙Output frequency (and hence motor speed) can be controlled by one of five methods:

(1)Frequency setpoint using the keypad.

(2)High resolution analogue setpoint (voltage input).

(3)External potentiometer to control motor speed.

(4)Fixed frequencies via binary inputs.

(5)Serial interface.

∙Built-in DC injection brake with special COMPOUND BRAKING.

∙Integral RFI filter on single phase input inverters (MM12 - MM300).

∙Acceleration/deceleration times with programmable smoothing.

∙Fully programmable single relay output incorporated.

∙External Options connector for optional multi-language Clear Text Display (OPM2) or optional PROFIBUS module.

∙Automatic recognition of 2, 4, 6 or 8-pole motors by software.

∙Integral software-controlled cooling fan.

∙Fast Current Limit (FCL) for reliable trip-free operation.

∙Compact design and the ability to mount inverters side by side provides greater space saving.
