1.1. Warnings
•
To avoid electric arcing and hazards to personnel and electrical contacts, never
connect/disconnect the servo drive while the power source is on.
•
Power cables can carry a high voltage, even when the motor is not in motion. Disconnect
the Falcon from all voltage sources before it is opened for servicing.
•
After shutting off the power and removing the power source from your equipment, wait at
least 1 minute before touching or disconnecting parts of the equipment that are normally
loaded with electrical charges (such as capacitors or contacts). Measuring the electrical
contact points with a meter, before touching the equipment, is recommended.
1.2. Cautions
•
The Falcon servo drive contains hot surfaces and electrically-charged components during
operation.
•
The maximum DC power supply connected to the instrument must comply with the
parameters outlined in this guide.
•
The Falcon can operate only through an isolated power source, using an isolated
transformer and a rectifier circuit. Power to this device must be supplied by DC voltage,
within the boundaries specified for the Falcon. High voltages may damage the drive.
The DC power supply voltage range is defined in the table in Section 4.3.
Safety margins must be considered in order to avoid activating the under- or over-voltage
protection against line variations and/or voltage drop under load. The transformer should
be able to deliver the required power to the drive (including peak power) without
significant voltage drops (10% maximum). While driving high-inertia loads, the power
supply circuit must be equipped with a shunt regulator; otherwise, the drive will be
disabled whenever the capacitors are charged above the maximum voltage.
•
Before switching on the Falcon, verify that all safety precautions have been observed and
that the installation procedures in this manual have been followed.
•
Do not clean any of the Falcon drive's soldering with solvent cleaning fluids of pH greater
than 7 (8 to 14). The solvent corrodes the plastic cover causing cracks and eventual damage
to the drive's PCBs.
Elmo recommends using the cleaning fluid Vigon-EFM which is pH Neutral (7).
