If a servo amplifier is turned OFF
in the same network, the servo
amplifiers connected after that one
cannot be used.
Use the connect/disconnect
function of SSCNET to turn
OFF/ON a servo amplifier in the
SSCNET network line.

warning
If the main circuit is turned OFF
while the servo OFF command
(M3215+20n) is ON, the [OC80
(E9.3): Ready-on signal on during
main circuit off] will be turned ON.

Changes/revisions
Set the servo amplifier's rotary switch
and connection according to the
SSCNET configuration.
Change "Number of pulses per
revolution" and "Movement amount per
revolution" of the fixed parameters
according to the resolution per the
connected servo motor revolution.
Use MR-MV200 SSCNETIII/H
compatible optical hub unit.
This function disconnects the network
connection of the servo amplifiers after
the disconnected one.
In order to turn off only a specific servo
amplifier, use MR-MV200 SSCNETIII/H
compatible optical hub unit.
Revise the program if it uses the servo
error code on the left.
The warning occurs when the main
circuit is turned OFF while the servo
OFF command (M3215+20n) is ON.
In order not to let the [OC80 (E9.3):
Ready-on signal on during main circuit
off] turn ON, change the PC18 servo
parameter from "0000(H)" to
"1000(H)".
