axis servo ON signal[Y1] and "[Cd.100] Servo OFF command".
• Control mode (b2, b3): Indicates control mode.
• Servo alarm(b7): Always OFF
• In-position(b12): Always ON

current value". (Refer to the 2nd and 3rd bullets of restrictions for
details.)

Function Operation
External signal selection function When "1: Servo amplifier" is set in "[Pr.116] FLS signal selection", "[Pr.117] RLS signal selection", and "[Pr.118] DOG
signal selection", the status of external signal at the amplifier-less operation mode start is shown below.
• Upper/lower limit signal (FLS, RLS): ON
• Near-point dog signal (DOG): OFF
Change "[Md.30] External input signal" to change the signal status. (Refer to the 3rd bullet of restrictions for details.)
When "2: Buffer memory" is set in "[Pr.116] FLS signal selection", "[Pr.117] RLS signal selection", and "[Pr.118] DOG
signal selection", the upper/lower limit signal (FLS, RLS) and near-point dog signal (DOG) follow the buffer memory
status of Simple Motion module during amplifier-less operation mode.
Torque limit function Turns ON/OFF torque limit ("[Md.108] Servo status1": b13) depending on "[Md.104] Motor current value". (Refer to the
3rd bullet of restrictions for details.)
