Amplifier-Less Operation Function - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

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)".
• The "SSCNET control (status) (SD508)" only changes into the execute waiting status (-1) even if the start
command of amplifier-less operation (-20) or release command of amplifier-less operation (-25) in
"SSCNET control (command) (SD803)". The actual processing is not executed. Set the execute command
(-2) in "SSCNET control (command) (SD803)" to executed.
• 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.
• 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.
• The amplifier-less operation becomes invalid immediately after the Multiple CPU system's power supply ON
or reset.
