COMBIMASTER & MICROMASTER Integrated
REFERENCE MANUAL

5. OPERATING INFORMATION

WARNING
The equipment must not be switched on until after its cover has been fitted and the cover
screws have been tightened to the correct torque.
After the power has been turned off, you must always wait five minutes so that the dc link
capacitors can discharge. Do not remove the cover until this time has elapsed.
All settings must only be entered by qualified personnel, paying particular attention to the
safety precautions and warnings.

5.1 General

For basic operation of COMBIMASTER &
MICROMASTER Integrated, no additional
equipment is required. However, for more
complex operation, Opm2 – Clear Text
Display is required (Opm2 is available as
an option, but must be ordered separately).
The inverter does not have a mains power
switch and is therefore live when the mains
supply is connected.
When delivered, the inverter has a frequency
setpoint range of between 0 Hz and 50 Hz.
Regardless of its initial position, internal
potentiometer R314 must be turned fully
counter-clockwise before it can be used to
start the COMBIMASTER.
R314 can be accessed by removing the
right-hand gland hole cover (see Fig. 2 &
3).
Connecting a serial link or the OPm2 to the
serial interface is made using the circular
connector SK200 (see fig. 2 & 3)

5.2 Basic Operation

There are two basic modes of operation for
the inverter.
Using the internal potentiometer only:
1
a For forward rotation, ensure that a
link is fitted between DIN1 (pin 5)
and P10+ (pin 1) on PL800/PL700
(see Fig. 4). For reverse rotation,
connect the link to DIN2 (pin 6)
instead of DIN1.
b Apply mains power. The green and
yellow LEDs will illuminate to show
that power is applied. Turn
potentiometer R314 fully counter-

Parameter settings can only be changed by
using either the serial interface (SK200) or
an optional Clear Text Display (OPm2).
Refer to the parameter list section in this
document for a full description of each
available parameter.
Analogue input type is selected by jumpers
JP300 and JP301. JP300 closed selects
current input, JP301 closed (default) selects
voltage input. These jumpers can only be
accessed when the cover is removed (see
Fig. 2 & 3).
If the motor is run unloaded
(e.g. for test purposes) and
vibration or trip conditions
occur, change P077 from 0 to
3 (requires OPm2).
clockwise. Turn the potentiometer
clockwise until the yellow LED
extinguishes. This indicates that
power is now applied to the motor.
Continue turning clockwise to
increase the speed of the motor.
Turn the potentiometer counter-
c
clockwise to reduce the speed of
the motor. Turning the
potentiometer fully counter-
clockwise causes the motor to slow
to a complete stop. Check that both
LEDs are illuminated (STANDBY
mode).
