13.3.6 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 (b) of 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 the 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 the 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
(Note)
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 13.3.1.)
