MICROMASTER 411 & COMBIMASTER 411 Operating Instructions
42 6SE6400-5CA00-0BP0
WARNING
COMBIMASTER411/MICROMASTER 411 operates at high voltages.
When operating electrical devices, it is impossible to avoid applying hazardous
voltages to certain parts of the equipment.
Emergency Stop facilities according to EN 60204 IEC 204 (VDE 0113) must
continue to function in all operating modes of the control equipment. Any
disengagement of the Emergency Stop facility must not lead to uncontrolled or
undefined restart.
Wherever faults occurring in the control equipment may lead to substantial
material damage, or even grievous bodily injury, (i.e. potentially dangerous
faults), additional external precautions must be taken or facilities provided to
ensure or enforce safe operation, even when a fault occurs (e.g. independent
limit switches, mechanical interlocks, etc.).
Certain parameter settings may cause the inverter to restart automatically after
an input power failure.
This equipment is capable of providing internal motor overload protection.
Refer to P0610 (level 3) and P0335, I
2 T is ON by default. Motor overload
protection can also be provided using an external PTC via a digital input.
This equipment is suitable for use in a circuit capable of delivering not more
than 10,000 symmetrical amperes (rms), for a maximum voltage of 460 V
when protected by an H or K Class fuse (see Table 7-6).
CAUTION
Only qualified personnel may enter settings in the control panels. Particular
attention must be paid to safety precautions and warnings at all times.
The COMBIMASTER 411 & MICROMASTER 411 is supplied with default
parameter settings that cover the following requirements:
The motor rating data, voltage, current and frequency are all compatible with
the inverter data.
Linear V/f motor speed, controlled by the control potentiometer.
Maximum speed 3000 min -1 with 50 Hz (3600 min -1 with 60 Hz), controllable via
the control potentiometer or by using a potentiometer via the inverter’s
analogue input.
Ramp-up time / Ramp-down time = 10 s.
If more complex application settings are required, please refer to the parameter
listing.
To change parameters you will need one of the optional modules "Basic Operator
Panel" (BOP), the "Advanced Operator Panel" (AOP) or the set-up software (on the
Docu-CD supplied).
