• The operation of following monitor data differs from the normal operation mode during amplifier-less operation mode.
n: Axis No. - 1
Storage item
[Md.30] External input signal
[Md.104] Motor current value
Storage details
Always "0".
Always "0".
Always "0".
• READY ON(b0), Servo ON(b1): Changed depending on the
"[Cd.191] All axis servo ON signal" and "[Cd.100] Servo OFF
command".
• Control mode (b2, b3): Indicates control mode.
• Gain switching (b4): Always OFF
• Fully closed loop control switching (b5): Always OFF
• Servo alarm(b7): Always OFF
• In-position(b12): Always ON
• Torque limit(b13): Changed depending on "[Md.104] Motor
current value". (Refer to the 2nd and 3rd bullets of restrictions for
details.)
• Absolute position lost(b14): Always OFF
• Servo warning(b15): Always OFF
Always "0".
Always "0".
Always "0".
Always "0".
• Zero point pass (b0): Always ON
• Zero speed (b3): Changed depending on the command speed
• Speed limit (b4): Always ON when the value other than "0" is set
to the command torque at torque control mode. Otherwise,
always OFF.
• PID control (b8): Always OFF
Operation
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
• Proximity 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 proximity dog signal (DOG) follow the buffer memory status
of Simple Motion module during amplifier-less operation mode.
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.)
Storage details
When "1: Servo amplifier" is set in "[Pr.116] FLS signal selection", "[Pr.117] RLS signal
selection", and "[Pr.118] DOG signal selection", the external input signal status can be
operated by turning ON/OFF the "b0: Lower limit signal", "b1: Upper limit signal" or "b6:
Proximity dog signal" during amplifier-less operation mode.
"0" is set at the amplifier-less operation mode start.
The motor current value can be emulated by changing this monitor data in user side
during amplifier-less operation mode.
