Local/Remote Application; Pid-Control Application - Honeywell NXS0003V35A2H1 Product Data

NXS VARIABLE FREQUENCY DRIVES

Local/Remote application

- The Local/Remote Control Application can be used in applications where the drive must be
controlled from two different locations. Control logic as the Basic application - i.e. no rewiring
needed.
- The control locations (A&B) are programmable and can be selected via digital inputs.
There can be separate references for operation and Start/Stop-inputs
-
- All inputs and all outputs are freely configurable
Multi-Step Speed Application
- The Multi-Step Speed Control Application can be used in applications where multiple fixed speeds
are required.
- A total of 15 +2 speeds are available:
o one basic speed (analogue voltage or current)
o 15 multi-step speeds
o one jogging speed.
Selection of the speeds is via digital inputs.
-
- Mechanical brake control available.
- All inputs and outputs are freely configurable

PID-Control Application

- The PID Control Application can be used where there is a need to keep a constant temperature or
pressure etc.
2 control locations available (by-pass of regulator possible)
-
Source A is PID-controller
-
o analogue input or a mathematical function of the analogue inputs
- Source B is a direct speed reference
o analogue input, a motorized potentiometer or control panel
- Stable control for a variety of tasks
- All inputs and outputs are freely configurable
