Note 1.
P: position control mode, S: speed control mode, T: torque control mode
2.
This is for the differential line driver pulse train input. For the open-collector pulse train input, connect as follows.
3. This diagram is for sink I/O interface. For source I/O interface, refer to section 3.9.3.
3.9.2 Detailed description of interfaces
This section provides the details of the I/O signal interfaces (refer to the I/O division in the table) given in
section 3.5. Refer to this section and make connection with the external device.
(1) Digital input interface DI-1
Turn on/off the input signal with a relay or open-collector transistor. The following is a connection
diagram for sink input. Refer to section 3.9.3 for source input.
(2) Digital output interface DO-1
A lamp, relay or photocoupler can be driven. Install a diode (D) for an inductive load, or install an inrush
current suppressing resistor (R) for a lamp load.
(Rated current: 40 mA or less, maximum current: 50 mA or less, inrush current: 100 mA or less) A
maximum of 2.6 V voltage drop occurs in the servo amplifier.
The following shows a connection diagram for sink output. Refer to section 3.9.3 for source output.
