• Function
This function, which is aimed at a retaining the load at standstill at its normal stop position, is used along
with the speed sensor vector control function to prevent the position of an elevator at standstill from
shifting.
Switching to position control takes place when the load is at a standstill.
The settings of these parameters take effect only in sensor speed control mode.

In speed control mode  or  specified with the V/f control mode section parameter (  ), simple positioning
control is performed upon receipt of a simple positioning signal, with the position at that time used as the reference
point (positional deviation: 0).
Ex.) When using the S4 terminal as the simple positioning signal input terminal
