You need to set P05.38=2 and P05.44=2 to connect the encoder to HDIA and HDIB. In
open/closed-loop mode, the encoder measures the encoder pulse count at the pulley side to calculate
the actual cable running distance of pulley. Before first running, perform upward limit calibration.
The procedure for first running is as follows:
1. Set the upward limit terminal. For example, set P25.03=64, which indicates the S7
terminal is used as for upper limit input.
2. Enable forward running (upward) and stop when the upward limit position is reached.
Then perform calibration. Reset P19.15, P19.16, and P19.17.
3. After the calibration, send the running command through the S2 terminal to run
downward. Check the values of P19.15, P19.16, and P19.17.
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. Reset P19.15, P19.16, and P19.17.
3. Send the running command through the S2 terminal to run downward only if the
downward limit terminal S8 is valid. P93.17 displays the height from the upward limit
position to the downward limit position and P93.18 displays 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 P19.15 displays the
