Wiring; Maintenance And Inspection - Parker FL20-CA Series Product Manual

1.4 Wiring


Do not connect a three-phase power supply to the U, V, or W output terminals.

Connect U, V and W of servo drive directly to U, V, and W of servo motor, and avoid using
MCtt when connecting.

When DO output connecting to relay, pay attention to the polarity of FWD (fly-wheel
diode). Otherwise, damage of servo drive may occur, and signal outputs abnormally.

Firmly fasten and securely connect power supply terminals and motor output terminals.

Do not connect 220V servo drive directly to 400V voltage.

Do not bundle the power cable and signal cable together or passing through in the same
pipeline. Keep both cables separated by at least 30cm.

Use twisted-pair shielded wires or multi-core twisted pair shielded wires for signal and
encoder cables.

The maximum length is 3m for reference input cable and the maximum length is 15m for
encoder cable.

Take appropriate countermeasures to potential interference when using the servo system in
following locations.

Locations subjects to static electricity or other forms of noise.

Locations subjects to strong electromagnetic fields and magnetic fields.

Locations subjects to possible exposure to radioactivity.

Repair or maintain servo drive only after the CHARGE indication goes off.

1.5 Maintenance and Inspection

 Repair or maintenance of the servo drive can be performed only by qualified personnel.
 Cut off all connections of servo drive before the insulation resistor test of servo drive.
 To avoid the discoloration or damage of cover, do not use petrol, diluent, ethyl alcohol,
acidic and alkaline detergent to clean.
 When replacing the servo drive, resume operation only after transferring the previous user
parameters to the new servo drive or computer.
 Do not attempt to change wiring while the power is ON.

Do not disassemble the servo motor.
