5.2 Basic Functions Settings
5.2.1 Servo ON Signal
This sets the servo ON signal (/S-ON) that determines whether the servomotor power is ON or OFF.
(1) Signal Setting
Note: Use parameter Pn50A.1 to allocate the /S-ON signal to another terminal. For details, refer to 3.3.1 Input Signal Allo-
cations for details.
(2) Settings for Continuous Servo ON Signal
Parameter Pn50A.1 can be used to enable the Servo ON condition constantly.
5.2.2 Polarity Detection
When using an incremental linear scale and a servomotor without any hall sensors, execute polarity detection
after the control power supply is turned ON.
The servo ON signal (/S-ON) can be received under the following conditions.
• The main circuit power supply is ON.
• No hard wire base block state
• No servo alarms
For details on the hard wire base block function, refer to 5.11.1 Hard Wire Base Block (HWBB) Function.

Setting Meaning
Input /S-ON
CN1-40
[Factory setting]
ON
Servomotor power is ON. Servomotor
can be
operated.
OFF
Servomotor power is OFF. Servomo-
tor cannot be operated.
Always input the servo ON signal before inputting the speed/position/force reference to
start or stop the servomotor. Do not input the references first and then use the servo ON
signal or turn ON/OFF the AC power supply to start or stop. Doing so will degrade inter-
nal elements and lead to accident. Input the servo ON sign
al while the servomotor stops.
While the servomotor is moving, the servo ON signal cannot be input.
Parameter Meaning

Enabled
Classification
Pn50A
n.0
[
Factory setting]
Inputs the servo ON signal from the input terminal
CN1-40.
After restart Setup
n.7 Constantly enables the servo ON signal.
SERVOPACK operation will be possible (i.e., power will be supplied) when the main cir-
cuit power supply is turned ON if the servo ON signal is set to be always enabled. When
inpu
tting speed/position/force reference, be sure to implement safety measures for
unexpected operation of the servomotor and machine.
SERVOPACK operation will be possible (i.e., power will be supplied) when an alarm is
re
set after an alarm occurs. The servomotor or machine may operate unexpectedly if an
alarm is reset while a reference is being input.
