Warnings, Cautions and Notes
The following Warnings, Cautions and Notes are provided for your safety and as a
means of preventing damage to the product or components in the machines
connected.
Specific Warnings, Cautions and Notes that apply to particular activities are
listed at the beginning of the relevant chapters and are repeated or supplemented
at critical points throughout these chapters.
Please read the information carefully, since it is provided for your personal safety
and will also help prolong the service life of your MICROMASTER 420 Inverter and
the equipment you connect to it.
WARNING
 This equipment contains dangerous voltages and controls potentially
dangerous rotating mechanical parts. Non-compliance with Warnings or failure
to follow the instructions contained in this manual can result in loss of life,
severe personal injury or serious damage to property.
 Only suitable qualified personnel should work on this equipment, and only after
becoming familiar with all safety notices, installation, operation and
maintenance procedures contained in this manual. The successful and safe
operation of this equipment is dependent upon its proper handling, installation,
operation and maintenance.
 The DC link of all MICROMASTER modules remains at a hazardous voltage
level for 5 minutes after all voltages have been disconnected. Therefore always
wait for 5 minutes after disconnecting the inverter from the power supply before
carrying out work on any modules. The drive unit discharges itself during this
time.
 This equipment is capable of providing internal motor overload protection in
accordance with UL508C section 42. Refer to P0610 (level 3) and P0335.
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 230/460 V
when protected by an H or K type fuse, a circuit breaker or self-protected
combination motor controller.
 Use Class 1 60/75 °C copper wire only with the cross-sections as specified in
the Operating Instructions..
 The mains input, DC and motor terminals carry dangerous voltages even if the
inverter is inoperative, wait 5 minutes to allow the unit to discharge after
switching off before carrying out any installation work.
NOTES
 Before installing and commissioning, please read these safety instructions and
warnings carefully and all the warning labels attached to the equipment.
 Make sure that the warning labels are kept in a legible condition and replace
missing or damaged labels.
 Maximum permissible surrounding ambient temperature is 50°C.

3 Factory setting
The MICROMASTER 420 frequency inverter is set in the factory so that it can be
operated without any additional parameterization. To do this, the motor parameters
set in the factory (P0304, P0305, P0307, P0310), that correspond to a 4-pole 1LA7
Siemens motor, must match the rated data of the connected motor (refer to the
rating plate).

4.2 Establishing communications between the
MICROMASTER 420 ⇔AOP
 Communications between AOP and MM420 are based on the USS protocol,
analog to STARTER and MM420.
 Contrary to the BOP, the appropriate communication parameters - both for the
MM420 as well as for AOP - should be set if the automatic interface detection
was not carried-out (refer to Table 4-1).
 Using the optional components, the AOP can be connected to the

4. output voltage (indicated by o – units V).
5. The value selected in P0005 (If P0005 is set to show any of the above
(1 - 4) then this will not be shown again).
Additional presses will toggle around the above displays.
Jump Function
From any parameter (rxxxx or Pxxxx) a short press of the Fn button will
immediately jump to r0000, you can then change another parameter, if
required. Upon returning to r0000, pressing the Fn button will return you to
your starting point.

If additional functions must be implemented at the drive inverter, use the following
Section "Commissioning the application". We recommend this procedure for
drives with a high dynamic response.
6.2 Commissioning the application
An application is commissioned to adapt/optimize the frequency inverter - motor
combination to the particular application. The frequency inverter offers numerous
functions - but not all of these are required for the particular application. These
functions can be skipped when commissioning the application. A large proportion
of the possible functions are described here; refer to the parameter list for
additional functions.
Parameters, designated with a * offer more setting possibilities than are actually
listed here. Refer to the parameter list for additional setting possibilities.

When defining the function of the digital inputs
(P0701 to P0703), three different types can be
selected for fixed frequencies:
15 = Direct selection (binary-coded)
In this particular mode, the appropriate
digital input always selects the associated
fixed frequency, e.g.:
Digital input 3 = selects fixed frequency 3.
If several inputs are simultaneously active,
then these are summed. An ON command is
additionally required.
16 = Direct selection + ON command
(binary-coded + On / Off1)
In this mode, the fixed frequencies are
selected as for 15, however these are
combined with an ON command.
17 = Binary coded selection + ON command
(BCD-coded + On/ Off1)
The BCD-coded operating mode is effective
for digital inputs 1 to 3.

frequencies.

NOTE
For settings 2 and 3, all parameters P1016 to

the drive inverter accepts the ON command.
