4. Installation instructions
4.1 When installing in an enclosure, ensure adequate
ventilation. The ambient temperature inust not exceed
450C.
Install the controller vertically with the terminals
at the top. Ensure that there is adequate ventilation.
Observe power losses. See 12.3.
4.2 When the switch RFR is closed, the controller is released.
4.3 Connect the potentiometer case to ground (PE).
4.4. Replace defective fuses only by the specified type.
5. Connecting instructions
5.1 Control cables must be screened. Connect screen at one side
of the controller with PE.
5.2 The control electronics carries mains potential when using
arinature voltage feedback with IxR coiupensation.
5.3 Before switching off the mains, the motor must have come
to standstill by opening the switch RFR or actuating the
quick stop.
For automatic mains switch—off, see 9, terminal ~.
5.4 Two—cruadrant operation. If only one motor direction is
required, e.g. clockwise rotation, terminal E of the set
value potentiometer is to be connected to terminal ~ or
(in case of anticlockwise rotation to terminals) and
terminal A to terininal ~. See chapter 3 connecting diagram.
5.5 Four—cruadrant operation. If both motor directions are
required, terminal A of tj~ set value potentiometer is to
be connected to terminal LJ and terminal E to terminal5j.
See chapter 3 connecting diagram. Zero speed results, when
the set value potentiometer n5011
<nset) is in the middle
position.
5.6 Separate supply of power stage and control electronics.
Caution: In case of separate supply of power stage and
control electronics, ensure a correct phase connection
betweeen power stage and control electronics.
5.6.1 Switch on control electronics and power stage at the
same time (standard application).
5.6.2 When switching on control electronics and then power
stage, note:
Caution: As long as the power stage is without current
the control inhibit must be active, see chapter 8.4
inching.

When connecting, check for the clockwise rotating field.
In case of an anticlockwise rotating field the wrong
phase sequence is displayed by lighting of the LED SEQ,
the firing pulses are inhibited.
Capacity of the +Vcc supply.
For a supply of external option boards, a total output
current of 5OmA is available.

With a mains voltage of less than 380V, the control
electronics must be supplied separately or by transformer as
shown in the drawing. The wire bridges BRl, BR2, BR3 and BR4
on the boards 4092 or 4093 must be removed.
Caution: Ensure by all means correct phase connection.
Incorrect connection results in fuse failure.
Please contact the factory, if your mains voltage is higher
than
415V.

7. Setting instructions
7.1 Turn trimmer ~ V , IxR fully anticlockwise. The trimmers
U1p~1
~nd
11fein are ~actory set for a standard set value
poEentiometer connection. Only when operating with a master
voltage, Uleit must be turned fully anticlockwise and ~fe1n
to middle position in order to enable subesequently a basic
setting. The trimmer ~ is factory set to nominal
controller current.
7.2 Setting of the current limit
This setting is only necessary when the motor current
is lower than the nominal controller current.
Turn trimmer ~ fully anticlockwise.
Connect a moving coil instrument in order to measure the
current to the armature cable; observe the polarity.
For positive set value the polarity at the motor
terminal A
is (+) and at teriainal B (—).
For negative set value the polarity at the motor
terminal A is (-) and at terminal B (+).
Block armature or disconnect when without voltage.
For armature voltage control disconnect cable to terminal5J.
Caution: Observe current capacity of the motor when at
standstill 1
Switch on the mains supply. LED ±Vcc and RSP light up. dose
switch RFR. LED RSP is not lit anymore.
Set speed setting potentiometer fully clockwise or set
master voltage
to nominal value. LED 1 lights up. Turn
1 clockwise, until the desired ariaa~~e current flows.
T~epermissible output current of the controller must not be
exceeded. See page 2, chapter 2, armature current.
open switch RFR. Connect the field. Reconnect supply cable
to terminal for armature voltage control.
7.3 donditions for setting see chapters 7.3.1 and 7.3.2
Connect a moving iron instrument as voltmeter to terminals A
and
B of the motor. When setting the speed, ensure that the
armature voltage does not exceed the permissible value of
U~jfl~~ = 400V.
7.3.1 Armature voltage control with IxR compensation
Connect
teriainal A of the motor to terlainalWof the
controller and
terminal B of the motor to terminal~
as shown in the connecting diagram. Set the set value
potentiometer or master voltage
to 0V. Open switch RFR.
Switch on mains. LEDs RSP and ±Vcc are lit. Set the set
value potentiometer or master voltage to maximum. For master
voltage operation turn trimmer ~ clockwise until +10 VDO
are applied at the measuring poinE Ml (measured to terminal
£~). Set the set value potentiometer or master voltage to
approx. 10% of the final value. dose switch RFR.
LED PSP is not lit.
