After correct configuration of the converter, check the operation of the ISP-12F adjuster
Start-up of the ISP-12F adjuster
To check the correctness of connections, follow the steps below:
-
After switching on the power supply, check whether the message ISP 12F is displayed. If
not, check the TSS 8/24 transformer connections and try again.
- After the ISP 12F message disappears, press the button of the manual control of the
headdownwards and check whether the head moves down; if the head moves in the
opposite direction (up) change positions of two out of three phase wires feeding the
head engine.
- Press and hold for a moment the “down” button of the manual control of the head on the
machine desktop. During manual lowering of the head, pay attention to whether the
dimension displayed in the “Saw Height” window decreases along with the downward
movement of the head. Similarly, by pressing the “up” button of the manual control of the
head, the dimension in the “Saw Height” window should increase along with the upward
movement of the head. If the counter malfunctions, i.e. the displayed value decreases
when the head is moved up and increases during the downward movement, swap the black
and the white wire (in the case of a rotary encoder) or the red and the orange wire (if the
MSK-320 magnetic encoder is used), (ENCODER, terminal In1, In2) and check the
operation of the counter again. Checking the correctness of counting is very important; if
the counting direction is not correct, the adjuster will not operate.
Finally, check that the limit switches limiting the movement of the head up and down
operate correctly. Limit switches should be fine-tuned to ensure safe stopping of the
head in extreme positions when reaching the full speed (test approach motion should be
at least 100 mm); when the movement stops, the adjuster displays the message “dn
STOP” or “UP STOP”, depending on the limit switch activated.
After activating the adjuster, the ATV 320 converter acceleration and deceleration ramp
time should be carefully selected (Table K-1, setting the electrical parameters of the
drive, ACC and Dec function).
The appropriate selection of ramp times should ensure the fastest possible acceleration
from the 0Hz frequency to the maximum operating frequency, as well as the fastest
possible release from the maximum operating frequency to 0Hz. The deceleration ramp
time must be selected so that even in the most adverse conditions, stopping the drive
does not cause the converter to enter emergency mode due to excessive voltage generated
at the motor terminals.
