J2
pos. 230
230Vac supply at terminals 25 and 26.
J2
pos. 400
400Vac supply at terminals 25 and 26.
NOTE:
If required, our transformer with code TR0102121 (instead of TR0102122) can be installed
as transformer TR3 to supply with voltage the terminals 25 and 26, according to the position of jumper J2,
415Vac or 440Vac.
J3
pos. L
Drive enabling at term. 18 (RUN) closing towards 0V, through insulated
relay contact or NPN transistor.
J3
pos. H
Drive enabling at term. 18 (RUN) closing towards a positive voltage of
0…30V
DC
, through insulated relay contact or NPN transistor.
J4
pos. V
Term. 7 configured as ramp input for a voltage speed reference of
0…+10V
DC
.
J4
pos. I
Term. 7 configured as ramp input for a current speed reference of
4…20mA (current
output
from term. 7).
J5
pos. I
Inner adjustment of current limit.
J5
pos. E
External control of current limit.

Presetting for mains supply with 60Hz frequency.
SW2 contacts

OFF
(bottom contacts)
Presetting for tacho generator feedback at
terminals 1 and 2.
SW2 contacts 1+2+3+4
⇒
⇒
ON
(top contacts:
ARM
)
Presetting of armature feedback, at high
impedance. In this case, the tacho generator signal
should NOT be present at term. 1 and 2.
Note: act on contacts SW2 only when term. 25-26 are NOT
supplied.
Note: under TACHO GENERATOR feedback, if you close
only
the key no. 4 (the right one) of SW2, you LOWER the max.
speed range, which can be obtained through trimmer RV9 (n
MAX) – up to 16…92V
DC
at term. 1-2.
