4.1 Inspection
4.2 Pre-start adjustments
Note: When tachometer
feedback is used, the auxil-
iary input is not available.
4.3 Starting
Ensure that the drive has been installed according to the previous
guidelines. Also, ensure that the unit has been wired according to the
schematics. Check that all connections are tight and that the motor can
rotate freely.
Before power is applied, confirm that the voltage selection plug (J5,
J6) on the AA1152 card matches the supply voltage. Factory default
setting is 240 vac.
The DF8 Plus drive has been preset for armature voltage feedback.
To use tachometer feedback refer to page 5, section 2.5, for complete
details.
Confirm that all jumper selections have been made correctly to ensure
proper drive performance (i.e. P1, JP1, JP5, JP6, see page 5).
All controls have been preset at the factory and should not require
further adjustment.
Before applying power, refer to section 6.0 and ensure that all control
and power wiring is correct, the power source, motor, and drive are
matched, and that all links are properly set. Turn the speed pot to the
zero reference position and ensure that the run circuit is disabled.
1. Apply power and observe that LED DS8 is illuminated. Press the
start button. LED's DS2 (Run) and DS3 (Inh) should turn on and
the motor should not rotate. If the motor rotates, see troubleshoot-
ing.
2. Slowly rotate the speed pot so that a negative reference is applied
to J1-5 (see section 6.0). LED DS5 (Fwd ref) and DS7 (Fwd out)
will intensify as the speed pot is increased to full and the motor
should rotate in the forward direction. If motor rotation is incor-
rect, remove power completely and interchange the motor arma-
ture connections. With link P1 in the bottom position, LED DS1
(ZSA) will illuminate when the motor is above zero speed.
3. With a positive reference applied to J1-5 (see section 6.0), LED's
DS4 (Rev ref) and DS6 (Rev out) will intensify as the speed pot
is increased to full and the motor should rotate in the reverse
direction.
4. With the speed reference set at maximum, the motor should rotate
at rated speed and/or voltage. If not, adjust RV4 for the correct
setting.
5. Press the stop button. With link P1 in the "IN" position, the motor
will coast to rest. If P1 is in the "OUT" position, the motor will
regenerate to zero speed.
6. If the acceleration and deceleration rates are not suitable, see
section 2.4, p.4, for adjustment.
