Pinout for the connector can be found in chapter "Connector Pinout" from p.72. Pinout of
the servo amplifier's end can be found in the instructions manual of the servo amplifier.

Important notes
Only staff qualified and trained in electrical engineering are allowed to wire up the motor.
High voltage up to 900V!
There is a risk of death or severe injury from touching exposed contacts.
Always make sure that the motors are de-energized during assembly
l
and wiring, i.e. no voltage may be switched on for any piece of equip-
ment which is to be connected.
Ensure that the switch cabinet remains turned off (barrier, warning
l
signs etc.). The individual voltages will only be turned on again during
setup.
Never undo the electrical connections to the motor while it is energi-
l
sed. Risk of electric shock ! In unfavorable circumstances, electric
arcs can arise causing harm to people and damaging contacts.
A dangerous voltage, resulting from residual charge, can be still pre-
l
sent on the capacitors up to 10 minutes after switch-off of the mains
supply. Even when the motor is not rotating, control and power leads
may be live.
Measure the DC-link voltage and wait until it has fallen below 50 V.
l
The ground symbol
must provide an electrical connection, with as large a surface area as possible, between
the unit indicated and the mounting plate in the switch cabinet. This connection is to sup-
press HF interference and must not be confused with the PE (protective earth) symbol
(protective measure to EN 60204).
To wire up the motor, use the wiring diagrams in the Installation and Setup Instructions of
the servo amplifier which is used.
