(4) How to insert the cable into Phoenix Contact connector
POINT
Do not use a precision driver because the cable cannot be tightened with
enough torque.
Insertion of cables into Phoenix Contact connector PC4/6-STF-7.62-CRWH or PC4/3-STF-7.62-CRWH is
shown as follows.
Before inserting the cable into the opening, make sure that the screw of the terminal is fully loose. Insert the
core of the cable into the opening and tighten the screw with a flat-blade screwdriver. When the cable is not
tightened enough to the connector, the cable or connector may generate heat because of the poor contact.
(When using a cable of 1.5mm2 or less, two cables may be inserted into one opening.)
Secure the connector to the servo amplifier by tightening the connector screw.
For securing the cable and the connector, use a flat-blade driver with 0.6mm blade edge thickness and
3.5mm diameter (Recommended flat-blade screwdriver: Phoenix Contact SZS 0.6
3.5). Apply 0.5 to 0.6
N

3.4 Connectors and signal arrangements
POINT
The pin configurations of the connectors are as viewed from the cable
connector wiring section.
(1) Signal arrangement
The servo amplifier front view shown is that of the MR-J3-20B or less. Refer to chapter 9 Outline Drawings
for the appearances and connector layouts of the other servo amplifiers.
The 3M make connector is shown.
When using any other connector,
refer to section 11.1.2.

3.5 Signal (device) explanations
For the I/O interfaces (symbols in I/O division column in the table), refer to section 3.7.2.
In the control mode field of the table
The pin No.s in the connector pin No. column are those in the initial status.
(1) Connector applications
Connector Name Function/Application
CN1A Connector for bus cable
from preceding axis.
Used for connection with the controller or preceding-axis servo amplifier.
CN1B Connector for bus cable to
next axis
Used for connection with the next-axis servo amplifier or for connection of the cap.
CN2 Encoder connector Used for connection with the servo motor encoder.
CN4 Battery connection
connector
When using as absolute position detection system, connect to battery (MR-J3BAT).
Before installing a battery, turn off the main circuit power while keeping the control
circuit power on. Wait for 15 minutes or more (20 minutes or for drive unit 30kW or
more) until the charge lamp turns off. Then, confirm that the voltage between P(
)
and N(
) (L and L for drive unit 30kW or more) is safe with a voltage tester and
others. Otherwise, an electric shock may occur. In addition, always confirm from the
front of the servo amplifier whether the charge lamp is off or not. Replace the
battery with main circuit power OFF and with control circuit power ON. Replacing
the battery with the control circuit power OFF results in loosing absolute position
data.
CN5 Communication connector The personal computer is connected.

operated.
Turn EM1 on (short between commons) in the forced stop state to reset
that state.
