TECHNICAL OVERVIEW & SUMMARY TABLE
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 - 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.
