10.1 INPUT SIGNAL SPECIFICATION
The DC input signals are those sent from the machine to the servo
unit.
They are transferred via a non-insulated interface that can be switched
between sink type (24V common) and source type (0V common)
except for an emergency stop input, which is fixed at a sink type (24
V common).
The relevant safety standards require that the interface be used as sink
type.
The contacts on the machine side must satisfy the following
requirements:
Contact capacity :
30VDC, 16mA or higher
Closed-state contact-to-contact leakage current :
1 mA or lower (at 26.4V) :
Closed-state contact-to-contact voltage drop :
2V or lower (including voltage drop across cable, with 8.5mA)
For information about the specifications of the skip signal, see
Section 10.4.
