Chapter 14 Common Functions
(2) The operation for external signal selection function of virtual servo amplifier
differs from the actual servo amplifier.
Function Operation
External signal selection function
When "1: External input signal of servo amplifier" is set in "[Pr.80] External input signal
selection", the external signal status immediately after power supply ON is shown
below.
• Upper/lower limit signal (FLS, RLS): ON
• Near-point dog signal (DOG): OFF
Change the signal status in "[Md.30] External input signal".
(Refer to "Restrictions (3)" for details.)
Torque limit function
Turns ON/OFF torque limit ("[Md.108] Servo status" high-order buffer memory
address: b13) depending on "[Md.104] Motor current value". (Refer to "Restrictions
(3)" for details.)
(3) The following monitor data of virtual servo amplifier differ from the actual
servo amplifiers. The writing operation is possible in the virtual servo
amplifier.

[Md.30] External input signal
When "1: External input signal of servo amplifier" is set in
"[Pr.80] External input signal selection", the external input
signal status can be operated by turning ON/OFF the
following signals.
• b0: Lower limit signal
• b1: Upper limit signal
• b6: Near-point dog signal

[Md.104] Motor current value
"0" is set after immediately power supply ON.
The motor current value can be emulated by changing this
monitor data in user side.
