6.5 Function and setting of servo on input (S-ON) signal
After servo on input (S-ON) signal is input, the motor will be enabled and can be operated. The function
and setting of S-ON signal will be described as below.
6.5.1 Function of servo on input (S-ON) signal
Table6.5.1.1
Type Signal Hardware Pin Status Description
Input S-ON CN6-33 (I1)
ON
The motor is enabled. Motion control can be
performed.
OFF
The motor is disabled. Motion control cannot be
performed.
Use Pt50A = t.X (Allocation of servo on input (S-ON) signal) to allocate S-ON signal to another pin.
For more information, please refer to section 8.1.1.
6.5.2 Setting S-ON signal to be always on
When Pt50A = t.X (Allocation of servo on input (S-ON) signal) is set to A (The signal is always
active.), it means the motor will be enabled when the power is turned on.
Table6.5.2.1
Parameter Description Effective Category
Pt50A
t.0
(Default)
User S-ON signal for servo on or servo off.
After power on Setup
t.A S-ON signal is always ON.
Set Pt513 to t.1 to allocate signal to the desired pin. For more information, please refer to section
8.1.1.
If S-ON signal is set to be always ON, when the main circuit power for the servo
drive is input, the motor will be enabled. Ensure safety measure is implemented to
avoid false operation if command is input at the same time.
When servo off (Power is not supplied to the motor.) occurs due to an alarm which is
resettable, the motor will automatically be in servo on state after the alarm is reset.
Please be noted that if the cause of the alarm is not cleared, the alarm may still
