15. SERVO AMPLIFIERS WITH A LARGE CAPACITY (30k TO 55kW) 
 
15.3.6 Converter unit signal (device) explanations 
POINT 
 
Explanations on the drive unit signals are the same as those for servo amplifiers 
with 22kW or less. Refer to section 3.5. 
 
 
(1) Signals 
For the I/O interfaces (symbols in I/O column in the table), refer to (2) in this section. 
 
Signal name 
Pin code  Pin No. Function/Application 
I/O 
division
Digital I/F power 
supply input 
DICOM CN1-1 
CN1-6 
Used to input 24VDC (24VDC 10  150mA) for I/O interface. The power supply 
capacity changes depending on the number of I/O interface points to be used. 
For sink interface, connect   of 24VDC external power supply. 
For source interface, connect   of 24VDC external power supply. 
 
Forced stop 
EM1 
CN1-7  Turn EM1 off to bring the motor to a forced stop state, in which the magnetic 
connector is turned off and the servo-off signal is output to the drive unit. 
Turn EM1 on in the forced stop state to reset that state. 
DI 
Trouble 
ALM 
CN1-2  ALM turns off when power is switched off or the protective circuit is activated. 
Without alarm occurring, ALM turns on within about 1.5s after power-on. 
DO 
Warning 
WNG 
CN1-8  When warning has occurred, WNG turns on. 
DO 
Digital I/F common  DOCOM 
CN1-5 
CN1-9 
Common terminal for the ALM and WNG output signals of the converter unit. 
Separated from LG. 
Pins are connected internally. 
For sink interface, connect   of 24VDC external power supply. 
For source interface, connect   of 24VDC external power supply. 
 
Magnetic contactor 
drive output 
MC1 
CNP1-1  Connect to the operation coil of the magnetic contactor. Always supplies the 
control circuit power since it is conducted with L
11
 in the converter unit. 
 
 
 
 
 
 
WARNING
 
Magnetic contactor wiring 
connector on the converter unit. 
Connected state may cause an 
electric shock. 
 
 
 
 
 
 
MC2 
CNP1-2  Connect to the operation coil of the magnetic contactor. When the converter unit 
receives a start command from the drive unit, it is conducted with L
21
 inside, the 
control circuit power is supplied, and then the magnetic contactor is turned ON. 
Change parameter No.PA02 setting to “
0” when controlling without 
magnetic contactor control connector (CNP1). (Refer to section 15.3.1.)
