Servo ON/OFF status selection at startup (Ver. 1.30 or later)

In the 20SSC-H Ver. 1.30 or later, it is possible to set the servo ON/OFF status to be selected when the PLC
(including the 20SSC-H) and servo amplifier are started up
In a 20SSC-H earlier than Ver. 1.30, the servo amplifier is turned ON when the PLC (including the 20SSC-H)
and servo amplifier are started up
*1. The term "started up" indicates the following status:
- When communication between 20SSC-H and servo amplifier is established after system reset of
the 20SSC-H is executed
- When communication between 20SSC-H and servo amplifier is established after the PLC
(including the 20SSC-H) and servo amplifier are powered on
- When communication between 20SSC-H and servo amplifier is established after servo series is
set
1. Servo ON/OFF status at startup
Set the servo ON/OFF status at startup in "Servo startup ON/OFF selection."

OFF command is "1 (ON)" at startup of the servo amplifier.
Update and setting of positioning parameters
Use the positioning parameter to select the servo ON/OFF status at startup.
This setting becomes valid when the 20SSC-H and servo amplifier are started up.
After this setting, it is necessary to start up again the PLC (including the 20SSC-H) and servo amplifier.
When "servo OFF" is selected as the servo amplifier status at startup
The "servo OFF" status is selected when the servo amplifier is started up. Specify the "servo ON" status
using the following procedure.
The "unit ready" (status information) is ON in the 20SSC-H.
The "ready ON" (servo status) is ON in the servo amplifier.
Set the servo OFF command (operation command 2) to OFF (0) to specify
the "servo ON" status.
(When "servo ON" is specified, "servo ON" (servo status) turns ON.)

Set the servo ON/OFF status to be selected when the servo
amplifier is started up (Ver. 1.30 or later).
1: Servo OFF
The "servo OFF" status is selected when the servo amplifier is
started up.
BFM #14202
Accordingly, it is necessary to specify the "servo ON" status
b8
using a sequence program.
0: Servo ON
The "servo ON" status is automatically selected when the
servo amplifier is started up. (This operation is same as the
operation in products earlier than Ver. 1.30.)
1: Servo OFF
Set this to turn the servo OFF.
BFM #619 b8
0: Servo ON
Reset this to turn the servo ON.
This bit is set upon completion of 20SSC-H boot-up after power-
on.
BFM #128 b9
(It is kept in the ON state until the power is turned off.)
All buffer memory values become valid after the bit is set.
This bit is set while the servo is ON.
BFM #164 b1
Cleared when the servo turns OFF.
