ROWAN ELETTRONICA S.R.L. - Via Ugo Foscolo, 20 - 36030 CALDOGNO (VICENZA) ITALY
5
DESCRIPTION OF CONNECTION TERMINAL BOARD
1 - 6 -7
ZERO VOLT for input/output signals.
1 - 2
A.R. contact connection (static run consent) or NPN open collector transistor; when open, assents
acceleration ramp motor rotation up to maximum set speed and causes RUN led illumination. Closed, it
removes voltage from the motor and set acc./dec. ramp to zero.
1 - 3
torque limitation 0 / +10VDC signal input:
0VDC = minimum torque / +10VDC maximum torque
1 - 4
+10VDC 3mA reference voltage output for speed and torque (max. 3kohm load) regulation external
potentiometers.
1 - 5
speed regulation 0 / +10VDC signal input:
0VDC = zero turns / +10VDC = max speed
1 = extreme
3 = cursor
torque limitation external potentiometer connection
4 = extreme
(active with S1 open) R = 10kohm
4 = extreme
5 = cursor
speed regulation external potentiometer connection
6 = extreme
(active with S3 open) R = 10kohm
For connection of the 2 wire potentiometer (R = 10kohm) close microswitch S3 and use terminals 5 - 6only .
7 - 8
tachogenerator type 20VDC / 2800 rpm input
9 - 10
regulated output for powering starting and power windings of single phase Rowan motor (max 230VAC 8A
for code 119/92 up to 1HP and max 230VAC 15A for code 119/92/2 - 2HP).
11 - 12
power supply 230 VAC ±10% 50/60 Hz. -
GROUND CONNECTION.
CIRCUIT SILKSCREEN - TRIMMERS, MICRO-SWITCHES, LEDS
