Connection of the drive control (refer to connectiondiagramm)
Ensure that your a.c. line voltage corresponds to the voltage shown on the type marking of the unit.
Terminal strip
1 – 2
AC input, voltage according to type marking on unit, frequency 50 or 60 Hz, terminal 1
-phase, terminal 2 -neutral.
3 – 4
Armature, terminal 3 + (positive), terminal 4 -(negative).
5 - 6
Field, terminal 5 + (positive), terminal 6 -(negative).
7 – 8
Drive control release, contact closed = released (run).
12
Reference input (positive) without acceleration. Input voltage depends on rating of re-
sistor R1, however max. voltage 150VDC Input current approx. 0,32mA at max. speed.
Calculation of R1 as follows:
R1 (kOhm) = 3 x U
E
(V) - 30
If terminal 12 is used, speed potentiometer must be disconnected.
Terminals 10 and 11 must be interconnected, min. speed potentiometer P1 must be
set fully counter clockwise.
13 - 14
DC tachometer, terminal 13 + (positive)(electronic ground), terminal 14 -(negative)
(approx. 150 V at rated motor speed). Matching of tachometer with R36.
9 - 10 - 11
Speed potentiometer, connect center to terminal 10, start to terminal 11 and end to ter-
minal 9. This potentiometer enables an infinite variable adjustment of the motor from
min. to max speed.

Drive control adjustment
Min. RPM
P1 Adjustment of minimum speed during operation.
Acceleration rate
P2 Adjustment of the acceleration time of the motor from min. to max. speed.
The acceleration time can be adjusted from 2 to 10 sec.
Max. RPM
P3 Adjustment for maximum speed during operation.
I x R compensation P4 This control permits to compensate for the voltage drop in the armature and in
the supply line when armature feedback control is utilized. When tachometer
feedback is used, set this potentiometer fully counter clockwise .
Current limit
P5 Adjustment of the requested armature current. Max. permissible armature cur-
rent 7A DC at TA-05KB and 10A DC at TA-1K.
Stability
P6 With this potentiometer the drive is dynamically adapted to the load.
