2.2 Name and Function of Each Part of the Controller
BK
Connection terminal for the brake forced-release switch to be used when the actuator is equipped with a
brake. Connect the opposite side of the switch to 24 VDC.
MPI, MPO
Contacts for cutting off the motor drive power to achieve a safety level of safety category 1.
MPI and MPO connect to the input side and output side of the motor power supply, respectively.
(If these contacts are not used, connect them using a jumper cable. The controller is shipped with MPI
and MPO connected by a jumper cable.)
24V Positive side of the 24-VDC input power supply.
N Negative side of the 24-VDC input power supply.
EMG
Connection terminal for the emergency stop circuit (for cutting of motor drive signals).
A common ground is used, so connect the opposite side of the emergency stop switch (or contacts) to
the positive side of the 24-VDC input power supply.
„ Model indication of the connected actuator type
The type, ball screw lead and stroke of the actuator are indicated. When connecting the cables, confirm that the
actuator is of the correct specifications.
Example of indication:
The actuator type is RA4C.
The ball screw lead is 5 mm.
The stroke is 200 mm.
SV (Green) --- Indicates whether or not the
servo is on.
ALM (Red) --- Indicates whether or not an
alarm is present or
emergency stop is actuated
The I/O signal type is indicated here.
NPN --- Sink type
PNP --- Source type
Connects the encoder cable.
DIF --- Differential line driver mode
OC --- Open collector mode
