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
*1
.
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
.
→
For parameters, control data and monitor data, refer to Chapter 11
*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
.
"
*2.
When "Servo OFF" is selected as the status to be selected at startup of the servo amplifier, the servo
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.

For setting of parameters, refer to Section 7.1
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.

OFF
The "servo OFF" status is selected when the servo amplifier is
started up.
Accordingly, it is necessary to specify the "servo ON" status
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.)

information
BFM #28 b9
BFM #128 b9
This bit is set upon completion of 20SSC-H boot-up after power-
on.
(It is kept in the ON state until the power is turned off.)
All buffer memory values become valid after the bit is set.
Servo ON
Servo status
BFM #64 b1
BFM #164 b1
This bit is set while the servo is ON.
Cleared when the servo turns OFF.
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.)
