7.2 J3 – Armature
Output and Tach-Generator
Feedback –
desired armature voltage by
placing J3 in the proper
position, "A90" or "A180."
See Figure 11A.
Note:
For
line input, J3 must be
set to "A90." For 230
input, the armature
voltage is normally
set for "A180." However, it is also possible to set the armature voltage to "A90" for
stepdown operation.
7.2.1 Tach-Generator Feedback (for use with 1800 RPM motors.) – Jumper J3 is also
used if tach-generator feedback is to be used. If a 7 volt per 1000 RPM tach-
generator is used, set jumper J3 in the "T7" position. For a 50 volt per 1000 RPM
tach-generator, set the jumper in the "T50" position. See Figure 11B.
Note: When using tach-generator feedback, the
IR Comp Trimpot (See Section 10.4, on
page 27) should be turned to a
minimum setting (full CCW). See
Figure 9, and Section 6.11, on page 19.
7.3 J5 - Speed (SPD) or Torque (TRQ).
Note: Factory setting of J5 is Speed
mode (Default).
In the speed control mode (J5 set to SPD), the
KBRG-212D will provide variable speed
control. The motor speed will be in direct
proportion to the input signal. Both forward and
reverse torque is used to stabilize motor
speed.
See Figures 12, 13 and 14.
