ECO REFERENCE MANUAL
5. TECHNICAL OVERVIEW & PRODUCT RANGE TABLES
The MICROMASTER Eco and MIDIMASTER Eco
inverters are intended for use anywhere in the
world and therefore support a wide range of
mains voltages:
3 phase 208 - 240V±10%
3 phase 380 – 460 / 480 / 500V ±10%
3 phase 525 - 575V±15% (MIDIMASTER Eco
only)

STANDARD FEATURES

• Easy to install program and commission.
• Fast Current Limit (FCL) for reliable trip-free
operation.
• to 50°C temperature range (0 to 40°C for
MIDIMASTER Eco).
• Factory default parameter settings pre-
programmed for European, Asian, and North
American requirements.
• Output frequency (and hence motor speed)
can be controlled by:
1. frequency setpoint using the keypad
2. High resolution analogue setpoint (voltage
or current input)
3. External potentiometer to control motor
speed
4. 8 fixed frequencies via binary inputs
5. Motorised potentiometer function (raise
and lower speed pushbuttons)
6. Serial RS485 interface
• Acceleration/deceleration times.
• Two fully-programmable relay outputs (13
functions).
• Fully-programmable analogue outputs (1 for
MICROMASTER Eco, 2 for MIDIMASTER
Eco).
• External options connector for optional multi-
language Clear Text Display (OPe).
• Dual Motor-parameter sets available if Clear
Text Display option (OPe) is fitted.
• Integral software controlled cooling fan.
• Side by side mounting without additional
clearance. (IP20/21 models).
• Optional protection to IP56 (NEMA 4/2) for
MIDIMASTER Eco inverters.
• Standard open loop quadratic V/F Control,
ideal for simple applications such as pumps
and fans.
• Range of drives benefits from the standard
inclusion of a PID controller for closed loop
system regulation.
• All products make use of the same, simple to
use, standard user interface consisting of
push buttons and LED display.
• User-friendly screwless terminals used for
control connections. (MICROMASTER Eco
only)
• RS485 serial interface is standard, allowing up
to 31 drives to be networked to a PLC or
Building Management System (BMS).
• Drive can be enabled via keypad, via digital
inputs or via standard RS485 serial interface.
• Motor speed set-point can be selected, using
a digital set-point, motorised potentiometer,
fixed frequency, analogue input or via the
RS485 serial link.
• Mixed mode control is also available, allowing
drive control and setpoint input to be from
different sources.
• Drives can be configured to start automatically
following a mains break or after a fault.
• Parameter sets are fully compatible between
different product types, reducing learning time.
• All drives are certified in accordance with
VDE, UL and Canadian UL, and are
manufactured to ISO9001.
• All drives conform to the requirements of the
EC low voltage directive 73/23/EEC and have
been awarded the CE mark.
