Leveling Switch

Pr.04-09 (1.5 m/s
) Inspection Deceleration

Pr.04-10 (0.2 m/s

Pr.04-11 (0.1 m/s
) Re-leveling Deceleration
Pr.04-18 (3.0 sec.) Low-speed Running Time
When Enabled Manually
Methods of Accurate Leveling for Re-leveling:
1. Install the leveling plate accurately
2. Adjust the clearance between upper and lower leveling switches. In general, the clearance is fixed and not allowed to adjust.
3. Adjust Pr.04-11 (Re-leveling Deceleration). In general, set Pr.04-11 to the minimum value and it is not allowed to adjust because setting it to a
larger value causes discomfort.
4. Adjust Pr.04-05 (Leveling Speed)
5. Adjust Pr.03-18 (Delayed Time for Leveling Switch). Pr.03-18 is valid only when used for stop at leveling with multi-step speed, and does not
affect hoistway auto-tuning and direct docking.

Pr.13-57 (Time for Decreasing Torque at Stop) is time that
triple rated current decreases to zero. The current of stopping
zero-speed is lower so it usually decreases to zero in advance.
