Goodrive350-19 Series VFD for Crane
used as for upper limit input.
2. Enable forward running (upward) and stop when the upward limit position is reached. Then
perform calibration.
3. Record the values of P93.14 (Initial turns of drum winding) and P93.13 (Per-layer turns of drum
winding), and clear the settings of P94.05, P94.06, and P94.07 to 0.
4. After the calibration, send the running command through the S2 terminal to run downward.
Check the values of PP94.05 (Measured height), P94.06 (High bits of height measuring pulse
count value), and P94.07 (Low bits of height measuring pulse count value).
If the downward limit position needs to be used as the reference point, the procedure for first running
is as follows:
1. Set the upward and downward limit terminals S7 and S8. For example, set P25.03=64 and
P25.04=65.
2. Enable forward running (upward) and stop when the upward limit position is reached. Then
perform calibration.
3. Record the values of P93.14 (Initial turns of drum winding) and P93.13 (Initial diameter of
drum/pulley diameter), and clear the settings of P94.05, P94.06, and P94.07 to 0.
4. The calibration is completed, which indicates proper running. P93.17 displays the height from
the downward limit position to the upward limit position, P93.18 displays the height using the
downward limit position as the reference point (the height is 0 at the downward limit position,
the height is positive when it is above the downward limit position, the height is negative when it
is under the downward limit position), and P94.05 displays the height using the upward limit
position as the reference point (the height is 0 at the upward limit position, and only downward
running is allowed when the upward limit position is reached, and P94.05 indicates the rope
droop length when the upward limit position is not reached).
