UNIDIRECTIONAL DRIVE FOR ROWAN THREE-PHASE HIGH SLIP MOTORS
Technical characteristics
-
CE product
Unidirectional drive for Rowan three-phase high slip motors (A series) with a maximum power of 3kW at 400VAC
and 1.5kW at 230VAC.
-
Standard commutable supply limits: 170/260VAC and 330/500VAC, frequency 50/60Hz.
-
Pre-set for speed control of Rowan 2-4-6-pole motors equipped with tachometrical dynamo of the 20VDC at 2800
revs./min. type.
-
Operates with linear acceleration and deceleration ramps which are adjustable from 0.02sec. to 25sec., with automatic
insertion of direct current braking with inertial loads. Direct current braking can be excluded.
-
Speed adjustment with 3-wire potentiometer (min. 2Kohm, max. 100Kohm), or 0 ÷ +10VDC differential signal. Speed
adjustment with 2-wire potentiometer is also possible, but only if 10Kohm.
-
Maximum current adjustment (maximum couple) using an internal trimmer, 10Kohm external potentiometer or 0 ÷
10VDC signal. An amperometric transformer (TA) which reveals the current absorbed by the motor should be
connected to adjust the current. The TA should have a maximum output of 4VAC/0.2A.
-
Maximum voltage adjustment for ALQUIST type operation, in the case of motors for winders.
-
Running permission input (PNP/NPN).
-
Stop in ramp input (PNP/NPN)
-
Tachometrical dynamo differential input
-
Emergency contact output, can be delayed from 1 sec to 15 sec because of overload, absence of line and motor
phase, absence of tachometrical dynamo and inverted tachometric polarity if the internal precision rectifier is not
used.
-
Led display of the running, stop in ramp, emergency, motor rotating, braking, power on functions.
-
Adjustment of the stability (from trimmer), acceleration ramp, deceleration ramp, maximum revs., minimum revs.,
maximum couple.
-
Logical parts and controlling circuits protected with 0.5A fuses.
-
Connection power and control terminal boards.
-
Working temperature external to the cabinet: -5°C to +40°C; internal to the cabinet: -5°C to +55°C;
-
Storage temperature:
-25°C to +70°C
-
Relative uncondensed humidity:
5 to 95%
-
Single version in an IP20 aluminium container, silk-screened with useful diagrams for operation control and calibration;
base dimensions and fixing template interchangeable with the two-way 380S/0 drive.
In conformity with the following norms: CEI EN 60204-1 EN 50081-2 EN50082-2 EN 61800-3
CAUTION: Accordance with the mentioned norms depends on the connection of the separately supplied filtering devices
and the scrupulous observance of the instructions given on page 10 by the installer.
