must be Low for at least 18.5 ms. The reset is performed when the
data bits are then High for at least 18.5 ms. A built-in logic circuit
prevents fault conditions.
When mains power is switched on, the frequency inverter performs
a self-test. The power module detects the following errors, which
can be read through the serial interface.
• Mains overvoltage, mains undervoltage
• Overvoltage in internal DC link
• Overcurrent (overload, short-circuit, ground fault)
• EEPROM and microprocessor errors
• Overtemperature in power module
• Overtemperature in motor (with thermistor or thermal switch
only) or interruption of motor line. For RA-SP-HE… this error
message is not detected by the power module. It is available as
diagnostics status through the parameter channel,
a page 111.
For RA-SP-341… , RA-SP-342…, RA-SP-341(230) and
RA-SP-343(230)… the following applies:
The device’s built-in fuses for the DC air solenoid is not reported
separately. For testing, a voltage measurement between pin 4 and
pin 6 is required. This test must be performed by a trained
electrician.
Auto configuration for servicing
When you replace a RA-SP with an identical device, the AS-
Interface® is automatically transferred.
Requirement:
• Auto-addressing mode is enabled (default setting for RA-IN).
• The 400 V~ supply and AS-Interface® are active.
Procedure:
X
Make the plug-in connections to the new RA-SP…
The key-switch is in its Off position. After no more than 0.5
seconds all error LEDs must have gone out.
X
Select HAND (manual) or AUTO operating mode.
Parameterization
The parameters of the frequency inverter DF5 are described in
manual AWB8230-1412.
The descriptions below include only those parameters that are
applicable for use of the RA-SP in the Rapid Link system.
The parameters can be changed only with the keypad DEX-KEY-10
or the Moeller parameterization software Drive-Soft
(
a page 105).
The speed control unit RA-SP is factory-configured for operation in
the Rapid Link system. Depending on your application, individual
functions of the RA-SP can be adapted to the assigned drive in one
of several ways:
• With a PC running the Moeller parameterization software
Drives Soft
• Through the keypad DEX-KEY-10
The PC or keypad is connected through the serial RS 422 port
(
a page 103), which is located under the screw cover.
The default settings of the RA-SP are:
• Acceleration time = 10 s
• Delay time = 2 s
• PTC monitoring enabled:
– On RA-SP2-34… PTC monitoring is performed in the power
module and is enabled through digital input 5.
– On RA-SP-HE… monitoring is independent of the power
module.
• Reference frequency 1 = 30 Hz
• Reference frequency 2 = 40 Hz
• Reference frequency 3 = 50 Hz
• Reference value potentiometer

(under the screw cover on the device front), about 10 Hz
h Caution!
The processor of the RA-SP contains parameters of
frequency inverter DF5, which can not be activated with
the Rapid Link system. Incorrectly parameter settings can
lead to undefined operating states and malfunction.
h Caution!
The parameters listed in this section must be changed
only by trained personnel and according to the
instructions in manual AWB8230-1412.
h Caution!
Do not connect or disconnect the connection cable
between HMI device and speed control unit in operation,
as this could cause unpredictable drive behaviour.
