4 AUXILIARY AND APPLIED FUNCTIONS

4.11.2 Amplifier-less operation function

This function is used to confirm for the operation without connecting the servo
amplifiers at the starting or debugging.
The start/release request of amplifier-less operation is set in SSCNET control
command (SD803), and status of the command accepting waiting or execute waiting
is stored in SSCNET control status (SD508).
Confirm the amplifier-less operation status by the amplifier-less operation status flag
(SM508).
POINT
(1) The SSCNET control status device (SD508) only changes into the execute
waiting status (-1) even if the start command of amplifier-less operation
1/2 (-20/-21) or release command of amplifier-less operation (-25) in SSCNET
control command device (SD803). The actual processing is not executed. Set
the execute command (-2) in SSCNET control command device (SD803) to
executed.
(2) Only the release command of amplifier-less operation can be accepted
during amplifier-less operation. The start command for the other amplifier-less
operation cannot be accepted.
(3) The operation of servo motor or the timing of operation cycle, etc. at the
amplifier-less operation is different from the case where the servo amplifiers
are connected. Confirm the operation finally with a real machine.
(4) The amplifier-less operation becomes invalid immediately after the Multiple
CPU system's power supply ON or reset.
