5.1 Preparations
Before switching on the servo amplifier for the first time
Check all the following points carefully before switching on a servo amplifier for the first time:
● Has all the wiring been performed correctly? Check the power supply connections particularly
carefully: Single-phase to L1 and L3, 3-phase to L1, L2 and L3.
● Double-check for damaged cables and insufficiently insulated terminals to eliminate any possi-
bility of short circuits.
● Is the servo amplifier properly earthed? Double-check for possible earth faults and short circuits
in the output circuit.
● Check that all screws, connection terminals and other cable connections are connected correctly
and firmly.
Cable routing
● The wiring cables are free from excessive force.
● The encoder cable should not be used in excess of its flex life.
● The connector part of the servo motor should not be strained.
Environment
Check the following point before initial startup:
● Signal cables and power cables are not shorted by wire offcuts, metallic dust or the like.
Parameters
Check the setting of parameters by the display of the controller or setup software.

DANGER:
● Before starting operation, check the parameters. Improper settings may cause some
machines to operate unexpectedly.
● The servo amplifier heat sink, regenerative resistor, servo motor, etc. may be hot while power
is on or for some time after power-off. Take safety measures, e.g. provide covers, to prevent
accidental contact of hands and parts (cables, etc.) with them.
● During operation, never touch the rotor of the servo motor. Otherwise, it may cause injury.

WARNING:
Incorrect parameter settings can damage or (in extreme cases) even destroy the connected
motor. Take great care when you are setting the parameters and double check the electrical and
mechanical specifications of the motor, your entire drive system and the connected machine
before proceeding.
