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, the upward limit position must be
calibrated.
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. Clear the settings of P19.15, P19.16, and P19.17 to 0.
3. 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. Clear the settings of P19.15, P19.16, and P19.17 to 0.
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
