Speed controller RA-SP

The following devices can be connected to the serial interface:
• Display unit DE5-KEY-RO3, for example for direct frequency
indication (connection cable DE5-CBL-…-ICL required).
• Keypad DEX-KEY-10 for parameterization (connection cable
DEX-CBL-…-ICS required).
With the Copy function, parameters can be read out of RA-SP
and copied to another RA-SP. This simplifies commissioning, for
example for series machines. For further information about
parameterization and operation of the DEX-KEY-10, see manual
AWB8240-1416.
• PC through connection cable DEX-CBL-2MO-PC (with built-in
RS 422/RS 232 interface converter). With the Moeller
parameterization software DrivesSoft (ftp://ftp.moeller.net/
DRIVES/SOFTWARE/) all parameters can be read and written. In
addition, parameters can be copied, saved and printed, and the
operating modes displayed graphically in a trend analyzer.
The parameters of speed control unit RA-SP2-34… are assigned
equivalent to frequency inverter DF5-340-... Basic functions
a section “Parameterization”, page 114.
Selector switch
The key-switches engage in all positions.
Key-switch
In operating mode HAND (key-switch) start, stop and direction
reversal are performed with selector switch REV-OFF-FWD
(REV = reverse, FWD = forward, OFF = stop and reset following a
fault detected by the power module). The selected direction is
indicated by the LED on the motor.
The speed control unit is controlled through AS-Interface
®
(from
interface control unit RA-IN). The AS-Interface
®
connection must
be established. The AS-Interface
®
Power LED in the AS-Interface
®
symbol is lit. The key-switch must be in AUTO position. Selector
switch REV-OFF-FWD has no function in this case.
The key-switches engage in all positions.
figure 113 indicates the interaction between automatic and
manual operation as well as the phase reversal switch.
