Parameters (Screen 1: Type of Motor Enable,
Adaptation to Parent Machine)
: Motor Enable Via Control Panel / Control Panel AND Standard I/O
Control panel: The Standard I/O interface signals All motors ON/OFF
(collective enable) and Enable motor are deactivated.
The motors can then only be enabled and switched on via the control panel.
In this case the melter can function even without a standard I/O connection to
the parent machine, e.g. if it is to be purged for maintenance purposes.
With the option Field bus communication , other enables may be required,
depending on the control mode selected (Fig. 4‐72 to 4‐79). Depending on
the control mode, the control panel may be deactivated (only parameter
display is possible).
Enable motor via Control Panel
Interface for line speed
When a field bus‐based control mode (field bus, field bus (extended), dual
and dual (extended)) is used, the source of the line speed signal can be
either the field bus (Fig. 4 ‐‐94, bottom) or the interface
Key‐to‐line mode
(XS5) (Fig. 4‐94, top).
Field Bus
Line Speed Signal
Either Analog or Frequency can be selected, and either Voltage or current
can be selected for Analog . Depending on what is selected, the keys not
used will be transparent and the units will change. 0-20 mA or 4-20 mA is
retrieved from the I/O board.
NOTE: Voltage or current and 0 - 20 mA or 4 - 20 mA must have been set on
the I/O board with the DIP switches (Refer to section Installation ). The switch
setting is loaded once when the melter starts up, and it is displayed on the
control panel.
Max. in key-to-line mode
For calibration with the signal (voltage, current or frequency) received from
the parent machine.
Example of operation with pilot voltage: The parent machine runs at
maximum speed. An input signal of 9.8 V (
actual value) is displayed. Then
set Max. in key-to-line mode to 9.8.
