lift application for nxl
1. INTRODUCTION
The NXL Lift Application can be used with modern Lift systems. There are functions included that
are required to achieve a smooth ride in the lift car. The I/O interface table includes the most
commonly needed signals in lift applications.
In the application, constant speeds are presented in [m/s], acceleration and deceleration are
presented in [m/s
2
] and jerks are presented in [s].
Mechanical brake control logic is designed to achieve smooth departures from and landings to
floor level. The brake can be set in various ways to meet the different requirements of lift motors
and lift control logic.
The used hardware can be any Vacon NXL frequency converter.
NXL supports only open loop operation.
Evacuation is not supported by NXL.
Choose NXS or NXP if evacuation is required.
All outputs are freely programmable. The inputs DIN3, DIN4 (AI1) and DIN5 (AI2) are also freely
programmable.
Start forward and reverse signals are fixed to input DIN1 and DIN2 (see next page).
An Expander board, OPT-AA will be needed to get the external inputs signals DIE1-DIE3.
These are as default settings used as speed reference selection inputs when digital inputs are
used as speed reference inputs. The relay output on this board (or the internal R01) can be used
for mechanical brake control.
It is possible to run without OPT-AA if DIN3, DIN4 and DIN5 are programmed as speed references.
But then there is no input signal available for other functions such as fault reset.
OPT-AI can be used in place of OPT-AA if thermistor input is needed.
OPT-AI is similar to OPT-AA board but the transistor output DO1 is not available on this board.
