6.8 Triggers
You can choose from up to three digital triggers or one analog trigger.
• Digital: The gates are controlled by inputs from the injection molding
machine, using rising and falling edges or pulse triggers.
• Analog: An external transducer mounted on the injection molding
machine detects the screw position and plate motions are linked to
the screw position.
CAUTION
The voltage for the digital input must be DC and a maximum of 24 V. If you
use an AC voltage or a voltage higher than 24 V, the servo drive will be
damaged and the controller cannot be used. Repair and replacement parts
will be required.
CAUTION
Examples of Triggers
The following shows a profile that uses a rising edge for its open trigger and a
falling edge for its close trigger.
To use a pulse trigger, choose a matching set of a rising trigger and a falling
trigger.
