Instruction manual 91/104 V9.2
Installation
Drawing 12
Connection of a numerical control (or PLC) with
unbal-
anced output
to a generic analogue input to provide a
reference.
4.4.10 Connector X12
Connect digital inputs.
Power supply voltage from 18Vcc to 30Vcc (nominal 24Vcc). Current absorbed 10mA. The status of each digital input is displayed
by the corresponding LED which indicates that the command is valid (see paragraph ”Yellow LEDs – Commands“ from page 76).
In the presence of severe disturbances it is recommended to use good quality shielded cables and connect the two ends of the screen to
ground. On the drive case, near the connectors, anchorages are available for screens (see Mechanical characteristics page 85).
Signal allocation to PINs:
1
DEN
Enable input of the drive. If this command is missing, the motor is free.
2
REN
“Ramp Enable“ input. Enable the speed ramp.
NOTE:
If the drive is controlled by a CNC, only the speed ramp on the CNC and not that of the drive must be used.
3
RTD
“Reset“ input. It allows you to exit the alarm state and restore the drive’s operation after removing the cause that gen-
erated it.
•
Alarm reset is only possible if the drive is disabled (led DEN off).
•
Alarm reset is only possible if the cause that generated it has been eliminated.
4
DI1
Digital input 1 programmable.
It is normally used to control the “Motor direction inversion".
5
DI2
Digital input 2 programmable.
It is normally used to enable “JOG " operation of the motor (see page 71).
6
DI3
Digital input 3 programmable.
Normally it is used to select the gain for the analog input AI1 (see page 39)
7
DI4
Digital input 4 programmable.
It is normally used to enable motor positioning on the selected position (see page 74)
8
D0V
0V digital inputs.
9
A0V
0V analog.
10
+24V
24Vcc
±20 % – 100mA max.

Below are some drawings to explain the correct connections to the X12 connector:
Drawing 13
Connection of contacts to send commands to the digital inputs of
the drive.
It is necessary to connect the D0V to 0V.
