YASKAWA SGMAH - Sequence I;O Signals

Sigma II User’s Manual Chapter 5: Parameter Settings and Functions
5 - 26
5.2.4 Sequence I/O Signals
Sequence I/O signals are used to control servo amplifier operation. Connect these
signal terminals as required.

Input Signal Connections
Connect the sequence input signals as shown below.
Note: Provide a separate external I/O power supply; the servo amplifier does not have an internal 24V
power supply.
• External power supply specifications: 24V ±1 V
DC
, 50mA minimum.
Yaskawa recommends using the same type of external power supply as that used for output circuits.
The function allocation for sequence input signal circuits can be changed.
See 5.3.3 Input Circuit Signal Allocation for more details.
The external power supply input terminal is common to sequence input signals.
